IL®H£AQ AS A MORPHOLOGICAL TOOL IN ARABIC GRAMMAR

The Arab grammarians differentiate between the ziy¢ada (augment) that introduces an element of meaning and the ziy¢ada that appends (yul−hiq) one morphological form to another. Having realized the potential of the concept of il−h¢aq (appending) as an analytical tool in morphology, the grammarians divided appended words into several types according to the number of the radicals in their roots and the type of ziy¢ada that is involved, and tried to justify forms and patterns with reference to a set of detailed rules which they elaborately describe. This paper deals with the issues the grammarians tackle in their study of il−h¢aq, such as its purpose, the possibility of analogically extending its examples, and the inapplicability of id ̄g¢am (gemination) to its patterns. It also examines how the grammarians use il−h¢aq to reduce considerably the number of morphological patterns that form a closed system, to explain away anomalous and rare patterns, and thus to limit deviation from the norm (qiy¢as) and to test the validity of a host of morphological issues.

necessitated close scrutiny of a host of mostly complex and rarely used words whose patterns are said to be the result of il− h¢ aq (appending), was motivated by their general tendency towards limiting the items that constitute a closed system-particularly, the number of patterns the available corpus of words should be divided into-and by their interest in using the rules that govern il− h¢ aq as testing devices to prove the validity of their more general morphological premises.This paper sets out to investigate the methods the grammarians used in their study of il− h¢ aq and to demonstrate how they tried to incorporate these rules within their overall system of morphological analysis.
1.2.Much of the material on il− h¢ aq is discussed in several scattered parts of the Kit¢ ab (esp.II,[8][9][10][11]197;[401][402][403], but S³bawayhi nowhere gives a definition of il− h¢ aq or formulates and lists together the rules that pertain to it.Equally scattered are the comments of Mubarrad (d.285/898) in his [204][205]244;II,225ff;III,88,IV,[3][4].M¢ azin³ (d.248/862), on the other hand, discusses the different aspects of il− h¢ ¢ aq in one part of his Taâr³f (I, 34-53), be it in less detail than in the Kit¢ ab or the Muqta− dab.However, Ibn … Ginn³'s (d. 392/1002) commentary on the Taâr³f complements its text to make it more or less comprehensive.Furthermore, as we shall see later, Ibn … Ginn³ makes several perceptive observations on il− h¢ aq as part of his unparalleled approach to linguistic analysis.
As for the most well-organized and comprehensive study of il− h¢ aq in the sources, it is obviously that of Astar¢ ab¢ aOE d³ (d.686/1287) in … Sar− h al-… S¢ afiya (I, 52-70).It is surprising, however, that some authors of major works on morphology barely mention a few rules about il− h¢ aq, as did Ibn ôUâf¢ ur (d. 669/1271) in his Mumtiô (I, 206-208), or sporadically mention its function without devoting a particular section or chapter to it, as did Ibn … Ginn³, who at times mentions, in his alphabetical list of − hur¢ uf (here, phonemes) in Sirr âin¢ aôat al-iôr¢ ab, that a certain − harf can have the function of il− h¢ aq (e.g., alif; II, 691-93). 1 1 It should be noted that Ibn … Ginn³, in his Sirr, generally avoids the use of the term il− h¢ aq, and uses the more general term ziy¢ ada instead.For instance, he mentions a large number of the examples of il− h¢ aq of t¢ aé, n¢ un (I, 167-69 for both) and w¢ aw (II, 594) without referring to il− h¢ aq.He might have preferred ziy¢ ada because it contrasts more directly with aâl (i.e., what is part of the word's root), since he tries to establish the contrast between what is augmented and what is a part of the root.Another possible reason is that since he investigates in his Sirr not only the morphological characteristics of the − hur¢ uf, but also their Many of the later sources also show little interest in il− h¢ aq, and it is remarkable that, unlike his commentary on Ibn … Ginn³'s al-Taâr³f al-mul¢ uk³ (64f.),Ibn Yaô³" s's (d.643/1245) most detailed work, … Sar− h al-Mufaââal, does not include a special chapter on il− h¢ aq (see sporadic mention of the term in VI,113,119,and IX,cf. Zama› h" sar³,Mufaââal,240,241,and 358, where the term il− h¢ aq appears only in the latter case).Also noteworthy is that Suy¢ uç t³ (d.911/1505) has an atypically short summary of the main issues of il− h¢ aq in his Hamô al-haw¢ amiô (II,-most of which relates to whether or not it is restricted to what the Arabs actually used-and only an incidental mention of il− h¢ aq as one of the kinds of ziy¢ ada in A" sb¢ ah (IV,137).
Finally it should be mentioned that works that deal with loan words usually cite il− h¢ aq as one of the main factors that affect the Arabicized forms of these loans.For example, … Gaw¢ al³q³ (d.540/1145) and oe Haf¢ a" g³ (d.1069/1659) mention several patterns that demonstrate this phenomenon (Muôarrab,8,and … Sif¢ aé,(36)(37), and Ibn Kam¢ al Pasha (d. 940/1533) has a lively discussion of its role in Arabicization and frequently refers to this role in analyzing particular examples (Ris¢ ala,47f.;and index,p. 153).This interest in the relation between il− h¢ aq and loan words, it may be noted, owes its origin to S³bawayhi's chapter on m¢ a uôriba min alaô" gamiyya (What has been Arabicized from foreign languages; Kit¢ ab, II, 342).
Since the above-mentioned authors are largely in agreement concerning the function of il− h¢ aq and the material that constitutes its corpus, we shall refer to them collectively unless we need to specify or indicate different views.
2.1.Although S³bawayhi does not give a formal definition of il− h¢ aq, his discussion of it includes all the elements later grammarians used in formulating its definition.These elements are the following: (a) that it is a ziy¢ ada; (b) that it causes triliterals to be appended to quadriliterals and quinqueliterals, and quadriliterals to be appended to quinqueliterals; (c) that this ziy¢ ada is different from the one which uniformly introduces an element of meaning; 2 (d) that the pattern of the appended word should syntactic traits, and refers to the introduction of particles by using the root L® HQ (e.g.,Sirr,II,325,332,384,396,etc.), he consciously tried to avoid the term il− h¢ aq for the sense of appending, so as not to cause confusion between the two types.
2 The meanings of the cited examples will be indicated only in cases where the semantic aspect is discussed, and the examples will be given mostly as phonologically conform to the pattern of the word to which it is appended, i.e., what can be referred to as the target pattern; (e) that the derivatives of the appended word should be congruent to the derivatives of the target word; and (f) that the rules of assimilation (idḡ¢ am), if applicable, should not be made operational in the appended word because this would change its pattern and hence its congruence to the word to which it is appended.Due to the highly complex nature of the subject, sections 2.2-2.4 will deal in more detail with the grammarians' views on the above elements, and we shall try later to examine issues of a more general nature that relate to the grammarians' use of this tool in their linguistic analysis.
2.2.The phonemes used for appending are mostly w¢ aw, and y¢ aé (e.g., kawà tar and − dayḡam, both appended to " gaôfar; and › hirwaô, and ôià tyar, both appended to dirham), but they also include, among others, 3 n¢ un (e.g., raô" san, appended to " gaôfar), m³m (e.g., dilqim appended to zibri" g), and alif (e.g., − habanç t¢ a-from the root ® HB® T, with the addition of n¢ un and alif-which is appended to − habark¢ a, itself with a final alif that is not part of the root).Such instances of augmentation with no recurring phonemes are often attributed to their basic roots by a semantic comparison between their apparent root and an assumed root with less radicals.A good example is that of dul¢ amiâ (shining), whose apparent root DLM− S is further reduced to a triliteral root semantically related to it, DL− S (cf.dal³â, daliâ, dil¢ aâ, and dal¢ aâ, all of which mean "shining"; see Ibn Man− z¢ ur, Lis¢ an, DL− S, and Zubayd³, Amà tila, 62).Thus, the m³m, according to the grammarians, appends dul¢ amiâ to " gu› h¢ adib, an authentic quadriliteral.
In addition to this, theoretically any phoneme can be used for appending if it recurs within the appended word. 4Examples include mahdad, › hidabb,ôaà tawà tal,qurç t¢ aç t,ôafan" ga" g,and qu" saôr³ra appended to " gaôfar,qimaç tr,farazdaq,qarab¢ us,qurç t¢ as,ôabanqas,and › huzaôb³la,respectively (Suy¢ uç t³,Muzhir,II,[35][36].The difference benouns because the sources use them much more than verbs to illustrate il− h¢ aq. 3 The phonemes of augment, including those used for il− h¢ aq, i. 4 See Bohas and Guilluame (1984, 109f.) for a discussion of il− h¢ aq by the addition of one of the letters of augment or by the recurrence of one of the roots, and the difference between the two types.
tween the first seven representative examples and their respective counterparts is that all members of the first group may be attributed to roots whose radicals are supposedly reducible to a number less than the number of radicals in the root of their counterparts to which they are appended.For example, ôaà tawà tal (stout, fleshy, and flabby) is apparently quinqueliteral like farazdaq, but since it is semantically related to the root ôOE TL (which indicates abundance, stoutness, flabbiness, etc., and which was augmented by the addition of w¢ aw and à t¢ aé, according to the pattern faôallal), it is considered triliteral in origin, unlike the loan word farazdaq, none of whose radicals may be reducible with reference to a triliteral or quadriliteral root to which it may be assigned.Similarly, − halak¢ uk (intensely black) is derived from a triliteral root ® HLK which indicates blackness, whereas its counterpart, qarab¢ us (part of a horse's saddle), also a loan word, is thought to have four radicals (q, r, b, and s) that must be considered part of its supposed root. 5Based on the above, the vast majority of the corpus of appended words may be divided into five types: 6 5 We chose our two examples from loan words because they clearly have irreducible roots, but it must be noted that Arabic quadriliterals and quinqueliterals may also have irreducible roots, as in " gaôfar and › huzaôb³la, both of which are mentioned as examples above.For other examples where the semantic aspect indicates the existence of il− h¢ aq, see Astar¢ ab¢ aOE d³, … S¢ ar− h, II, 333 f.In certain cases, both the rules of augmentation and the semantic resemblance between the appended word and other derivatives from the same root point to the existence of il− h¢ aq.One example is kawà tar (abounding in good), whose w¢ aw, according to Ibn … Ginn³ (Taâr³f,16), is an augment for two reasons, namely, that the word has three radicals other than the w¢ aw, and that the meaning of abundance is present in the word kaà t³r, which is derived from the same root as kawà tar.
6 The use of il− h¢ aq in the classification of words according to the number of their radicals should be distinguished from its use by some lexicographers for a similar classification into triliterals, quadriliterals and quinqueliterals.What a lexicographer like Ibn Durayd means by saying that certain words are "annexed" to the quinqueliterals (ul− hiqa bi-l-› hum¢ as³) is that it is easier to classify them with the quinqueliterals as a distinct group, and not that they were made to conform to one of the patterns of the quinqueliterals as the more common use of the term il− h¢ aq implies.This explains why in the pattern fuô¢ alil, for example, dul¢ amiâ and " gu› h¢ adib, considered by the grammarians to be triliterals appended to an augmented quadriliteral (see the second type mentioned in the text above), both appear in Ibn Durayd's … Gamhara (II, 1210, 1212) as examples of words that are "annexed" to quinqueliterals.In other words, Ibn Durayd is interested here in il− h¢ aq as a tool for classifying words in exhaustive lists, and not in the i.Triliterals appended to quadriliterals: e.g., " gadwal (… GDL) and raô" san (Rô… S), compared with " gaôfar (… GôFR); and du› hlul (Doe HL) and − hulkum (® HLK), compared with burà tun (BROE TN).
Since words cannot have more than five radicals, il− h¢ aq does not affect quinqueliterals (li-anna ban¢ at al-› hamsa laysa war¢ aéah¢ a " sayé min al-aâl fa-yul− haq bi-hi; Ibn … Ginn³,Munâif,I,51).In other words, because there is no target pattern which the quinqueliterals can be appended to, il− h¢ aq was not applied to them, and they had to be placed outside the closed system which il− h¢ aq represents (see 3.3 below).
2.3.At the level of meaning, the grammarians draw a sharp distinction between il− h¢ aq and augmentation through which patterns that indicate certain meanings are formed.Of course, this latter type is much more widespread than il− h¢ aq and may be viewed as derivation (i" stiq¢ aq) par excellence, 8 whereas il− h¢ aq is a special type of derivation whose relative frequency of use is quite limited.This not withstanding, the grammarians consider the two types to be on an equal footing in the process of deriving words since they consider each of them to be representative of a distinct purpose of ziy¢ ada.As noted in 1.1 above, S³bawayhi (Kit¢ ab, II, 9) theoretical aspect of il− h¢ aq as discussed by the grammarians.
7 Augmentation here mostly means the addition of a diphthong or a long vowel (¢ a, ¢ u, or ³), probably since these, unlike short vowels, appear in writing.
8 It is noteworthy that some grammarians use il− h¢ aq to distinguish between taâr³f (morphology) and i" stiq¢ aq (derivation).Their argument is that the former is more general than the latter specifically because il− h¢ aq may be included under taâr³f but not under i" stiq¢ aq (Suy¢ uç t³, Muzhir, I, 351).
alluded to the distinction between two kinds of ziy¢ ada, one of which appends one form to another (tul− hiq bin¢ aéan bi-bin¢ aé), while the other introduces an element of meaning (tad› hul li-maôn¢ a).M¢ azin³ also makes this distinction (Taâr³f, I, 13, and Ibn … Ginn³, Munâif, I, 13-17), but in a less direct way.Based on the purpose of ziy¢ ada, he classifies it into four types: (a) the ziy¢ ada of il− h¢ aq, which appends one form to another; (b) the ziy¢ ada for vowel prolongation, such as ôa" g¢ uz and " gar³b; (c) the ziy¢ ada that indicates a meaning (maôn¢ a), such as n¢ unation (tanw³n) and the prefixes of the imperfect (− hur¢ uf almu− d¢ araôa); and (d) the ziy¢ ada that is inseparable from the word because the very meaning (maôn¢ a) of the word is dependent on the augmented pattern, e.g., the alif and t¢ aé of iftaqara, which have been part of the pattern iftaôala since it was first coined (wu− diôa) and used instead of *faqura.A closer look at this apparently more elaborate classification, however, readily reveals that it is essentially consistent with S³bawayhi's, since it contrasts il− h¢ aq with the ziy¢ ada that indicates meaning.Of the latter type are (c) and (d) above, where the word "meaning" is used in M¢ azin³'s text, as well as (b), since vowel prolongation is part of the structure of several patterns that are indicative of meaning, as in M¢ azin³'s own example, ôa" g¢ uz, of the pattern faô¢ ul, which indicates a common adjective for both masculine and feminine, and which has a plural, ôa" g¢ aéiz, that is exclusively indicative of the feminine (S³bawayhi,Kit¢ ab,II,208;cf. II,131, where the w¢ aw in ôa" g¢ uz is contrasted with the ziy¢ ada of il− h¢ aq).
Ibn ôUâf¢ ur's classification of the types of ziy¢ ada (Mumtiô, I, 204-6) is even more elaborate than M¢ azin³'s, since it includes types that are either purely phonological, such as the h¢ aé of quiescence (h¢ aé al-sakt), or that do not strictly qualify for inclusion under separate headings, such as the feminine ending of zan¢ adiqa-called t¢ aé (or h¢ aé) of compensation (t¢ aé al-ôiwa− d) on the assumption that it compensates for the elided y¢ aé9 in zan¢ ad³q-which actually belongs to a pattern that indicates the plural, and hence meaning.Taking this into consideration, the core of Ibn ôUâf¢ ur's classification is basically in agreement with that of S³bawayhi and M¢ azin³.
The distinction of the grammarians between the ziy¢ ada of il− h¢ aq and the ziy¢ ada of maôn¢ a raises the problem of those appended words which apparently do carry an element of meaning due to their augment.An example of such words is − hawqala (said of a man who ages and becomes weak), which is appended to fawôala (Ibn ôUâf¢ ur, Mumtiô, I, 167), and whose meaning is not identical to the original verb, − haqila (said of a camel that suffers indigestion after drinking water mixed with sand).To resolve this discrepancy, Astar¢ ab¢ aOE d³ uses this example, among others (… Sar− h, I, 52-53), to introduce a vital component to the definition of il− h¢ aq, and hence to the distinction between il− h¢ aq as a ziy¢ ada that is described as not having to do with meaning and the ziy¢ ada that indicates meaning.In his terms, the ziy¢ ada of il− h¢ aq is ḡayr muç tç tarida f³ if¢ adat maôn¢ a, that is, it does not systematically add a well-defined element of meaning.It is this unsystematic characteristic of il− h¢ aq that truly distinguishes it from the ziy¢ ada that systematically introduces a discernible element of meaning and is therefore outside the sphere of il− h¢ aq, as is the case in the hamza of éakbar and éaf− dal, which, he says, consistently expresses the comparative (taf− d³l), and the m³m of the pattern mifôal, which consistently indicates the instrument (… Sar− h, I, 53; II, 332).
2.4.At the purely formal (laf− z³) level, the grammarians identify several rules associated with il− h¢ aq.These rules, scattered as they are in the earlier sources, were assembled by some later authors either to formulate an accurate definition of il− h¢ aq, as did Astar¢ ab¢ aOE d³ (… Sar− h, I, 52), or to list each criterion (− d¢ abiç t) that reveals the use of il− h¢ aq, as did Suy¢ uç t³ (Hamô,II,216).In this respect too, the grammarians seem to be most interested in the distinction between ziy¢ ada of il− h¢ aq and ziy¢ ada of maôn¢ a. Indeed, their discussion centers on two main aspects which endorse their distinction of the two types.The first aspect is the congruence between the appended word and the word to which it is appended with regard to the number of radicals and the metric measure (wazn), i.e., the pattern of − harak¢ at and sakan¢ at (occurrence or non-occurrence of vowels after consonants).This congruence, the grammarians stress, should also apply to the derivatives of both words, that is, in the case of verbs (usually cited in the perfect), it should manifest itself in the imperfect, the imperative, the verbal noun, the active participle, and the passive participle, and in the case of nouns, it should appear in the diminutive and broken plural forms.Without going into details and exceptions to this general guideline of congruence, suffice it here to say that it was used to show the underlying difference between what is mul− haq and what is not.
For example, Astar¢ ab¢ aOE d³ (… Sar− h, I, 55; cf.Ibn … Ginn³, oe Haâ¢ aéiâ, I, 222, 232) argues that the inclusion of the verbal noun in the above list of de-rivatives that manifest congruence between the words that are appended and the words they are appended to should disqualify patterns such as afôala, faôôala, and f¢ aôala from being appended to the verb da− hra" ga, with which they rhyme, since their verbal nouns, ifô¢ al, tafô³l and muf¢ aôala, are not congruent with the verbal noun of da− hra" ga, which is da− hra" ga(tun), of the pattern faôlala(tun).Similarly, in nouns, the insistence that congruence should apply in broken plurals, 10 according to Astar¢ ab¢ aOE d³ (ibid., I, 56), readily shows that − him¢ ar, in spite of being metrically equivalent to qimaç tr, cannot be considered appended to it, since its broken plurals, − humur and a− hmira, are not of the same pattern as qam¢ aç tir.Obviously, the inclusion of such peculiarities of il− h¢ aq in its definition in Astar¢ ab¢ aOE d³'s … Sar− h (I, 52) is the reason why this definition, whose aim is to exclude other phenomena, is unusually long and detailed.
The second aspect which the grammarians focus on in the distinction between the ziy¢ ada of il− h¢ aq and the ziy¢ ada of maôn¢ a at the formal level is that idḡ¢ am (gemination) applies to the latter but not to the former. 11 S³bawayhi notes the difference between these two types of ziy¢ ada as to the applicability of idḡ¢ am, and devotes a chapter to those appended words whose final radicals are reduplicated but not geminated (Kit¢ ab, II, 401-402; cf.II, 408).Thus, he contrasts qardad, which is appended to " gaôfar and salhab, with maradd, originally *mardad, and attributes the lack of idḡ¢ am to il− h¢ aq itself.The aim of the contrast between qardad and *mardad is to show that idḡ¢ am, for which both words qualify according to their phonological structure, becomes inoperable in the presence of il− h¢ aq.In fact, S³bawayhi argues that idḡ¢ am does not take place in such appended words because the speaker intentionally keeps the last two radicals separate in order to achieve il− h¢ aq through the augment (lam tudḡim li-annaka innam¢ a aradta an tu− d¢ aôif li-tul− hiqahu bi-m¢ a zidta bida− hra" gtu wa-" ga− hdaltu).This is why in " galbaba, he says, the two b¢ aés are not geminated, hence the use of the forms " galbabtuhu, mu" galbab, " gulbiba, ta" galbaba, yata" galbabu, and the like, which are appended to their counterparts derived from da− hra" ga, such as tada− hra" ga, yatada− hra" gu, and da− hra" gtu (Kit¢ ab, II, 401; cf.F¢ aris³, Taôl³qa, V, 156-57; Mubarrad, Muqta− dab, I, 204-205, 244).Ibn ôUâf¢ ur (Mumtiô, I, 207) 10 See S³bawayhi's Kit¢ ab, II,197 and 211, for examples of the broken plurals of appended words.
lends further support to this line of thinking by arguing that speakers tolerated the heaviness of two separate radicals (i− htamal¢ u à tiqal i" gtim¢ aô almià tlayn) in such examples in order for their patterns to remain congruent to the words to which they were appended.This structural identity, so to speak, of appended words was viewed by Ibn … Ginn³-whose unremitting quest for exploring the underlying principles of linguistic phenomena is largely unrivalled in the Arabic tradition-as part of a more general tendency which he detects in a host of examples (oe Haâ¢ aéiâ, III, 232-40; esp.232-33) and which he discusses under the title al-imtin¢ aô min naq− d al-ḡara− d (refusal to contradict the objective).The essence of his argument, in the case of il− h¢ aq, is that its objective of achieving congruence between appended words and what they are appended to would have been annulled if normal idḡ¢ am been applied, and thus the Arabs refrained from applying the rules of idḡ¢ am to appended words because it was necessary to protect (− hir¢ asa) and preserve (− hif− z) the original purpose.Apart from the fact that this explanation presupposes a conscious effort on the part of the speaker, its inclusion with allegedly comparable phenomena is an attempt to show that il− h¢ aq, which represents an anomalous case with regard to the rules of idḡ¢ am, is not necessarily anomalous in other respects.In connection with this, we shall try to show later (see 4.2 below) how the grammarians incorporated the phenomenon of il− h¢ aq within the general grammatical system, as they saw it, by applying to it the same criteria of analysis that they use in other cases.
3.1.Based on the elements that they included in defining il− h¢ aq (see 2.1 above), and on their distinction between the ziy¢ ada of il− h¢ aq and the ziy¢ ada of maôn¢ a both at the level of meaning and form (2.3 and 2.4 respectively), the later grammarians were well-disposed toward assigning to il− h¢ aq an ultimate purpose that would justify its existence as an independent phenomenon.In this respect, it seems that they wanted to surpass the earlier grammarians, who merely stated that the ziy¢ ada of il− h¢ aq appends one word to another (tul− hiq bin¢ aéan bi-bin¢ aé; see S³bawayhi, Kit¢ ab, II, 9, and M¢ azin³, Taâr³f, I, 13) and did not go beyond this selfexplanatory level to determine a more specific purpose for il− h¢ aq. 12 The usual view among the later grammarians is that the ultimate purpose of 12 The same may be said of Mubarrad and Ibn al-Sarr¢ a" g (d.316/929), who cite a large number of appended words (Muqta− dab, see 1.2 above; and Uâ¢ ul, esp. the chapter on abniya, III, 179-222) but do not cite any particular purpose for the phenomenon itself.
The inadequacy of this argument is nonetheless evident to Ibn … Ginn³, who alludes to his teacher's view, both in oe Haâ¢ aéiâ and Munâif, as part of his discussion of M¢ azin³'s distinction between those appended forms that are qiy¢ as³ (regular, analogically extended) and those that are sam¢ aô³ (unproductive, restricted to attested material).In fact, Ibn … Ginn³ seems to alert the reader to the limited applicability of F¢ aris³'s view.He does this not only by giving an account of their discussion, during which Ibn … Ginn³ asks whether it would not be tantamount to inventing speech (afatarta" gil al-luḡa irti" g¢ alan; oe Haâ¢ aéiâ, I, 359; cf.Munâif, I, 44), but also by supporting M¢ azin³'s view that analogical extension does not apply to any of the appended forms other than those of the pattern faôlal, such as mahdad and " galbab, where the third radical is duplicated (Munâif, I, 42), and thus forms like " gawhar, bayç tar, " gadwal, − hiOE dyam, rahwak, arç t¢ a, miôz¢ a, salq¢ a, and " gaôb¢ a (oe Haâ¢ aéiâ, I, 358) are restricted to sam¢ aô.Moreover, the issue of the qiy¢ as³ versus the sam¢ aô³ nature of il− h¢ aq is presented by Suy¢ uç t³ (Hamô, II, 217; cf.Ibn M¢ alik, Tash³l, 299) as a subject of controversy among three parties.The first of these restricts il− h¢ aq to sam¢ aô, unless the grammarians need to create words with which to train students, whereas the second party-to which F¢ aris³ belongs-puts no restraints on analogically extending its attested examples.The third party is more selective since it resorts to the criterion of frequency of usage to determine the permissibility, or otherwise, of allowing analogical extension.
The other problem related to F¢ aris³'s view that ittis¢ aô is the ultimate purpose of il− h¢ aq is that, as we learn from some grammarians, the same ).The other part of the problem is evident in Astar¢ ab¢ aOE d³'s explanation of Ibn al-® H¢ a" gib's text, since he asserts that the notion of − h¢ a" ga (need), rather than tawassuô, is the real purpose of using the ziy¢ ada of il− h¢ aq as well as other kinds of ziy¢ ada, such as that of the active participle, the passive participle, and the verbal noun.Astar¢ ab¢ aOE d³ then hastens to say that it is also possible to explain the ziy¢ ada of il− h¢ aq by tawassuô.
It is evident from the above that the grammarians, starting with F¢ aris³, were trying to justify the existence of il− h¢ aq by assigning a purpose to it, just like other morphological phenomena which they associated with distinctive purposes.By insisting, however, on determining this purpose more specifically than did earlier grammarians such as S³bawayhi and M¢ azin³, who merely stated that il− h¢ aq appends certain words to others, these grammarians actually failed to appreciate why their forerunners acknowledged il− h¢ aq as a distinct phenomenon, and consequently why they contented themselves, in determining its purpose, with explaining what it does, and stopped short of seeking a more specific purpose to ascribe to it.
3.2.In order to understand the significance of il− h¢ aq for the earlier grammarians, and particularly with regard to the difference we have just mentioned between them and their successors, it is more appropriate to speak of the role that they assigned to il− h¢ aq in their analysis than of the purpose that it serves from the angle of the speaker.In other words, the early grammarians, most notably S³bawayhi and M¢ azin³, treated il− h¢ aq as a phenomenon in its own right and did not consider it to be part of any larger phenomenon because they realized its huge potential as a tool of morphological analysis.Theoretically speaking, they could have considered it to be a kind of i" stiq¢ aq whose examples are characterized by the use of certain phonemes and/or the repetition of others, and so on (e.g., say that − halak¢ uk is derived from the root ® HLK with the introduction of the long vowel ¢ u and the repetition of k).Alternatively, they could have said, as some lexicographers did (see n. 6), that these examples are of the same patterns as those words to which they are appended and could thus effectively have avoided the need to speak of il− h¢ aq (e.g., − halak¢ uk would be-regardless of the number of its radicals as explained in 2.2 aboveon an equal footing with qarab¢ us, both of the pattern faôal¢ ul, and not appended to it).The fact that they chose to think of it as a distinct phenomenon, therefore, was not dictated by the nature of the corpus of words that were considered to be examples of it-unlike, for example, the three other kinds of ziy¢ ada that M¢ azin³ mentions (see 2.3 above) and that are linguistic realities that naturally represent undeniable and selfexplanatory distinct phenomena.In effect the early grammarians were responding to their own interest in what they perceived as a major analytical tool.This explains why they were not concerned with what its purpose is from the point of view of the speaker.As for the later grammarians' search for a purpose for il− h¢ aq grounded in pragmatics rather than pure analysis, it is now evident that it went against the very reason why the earlier grammarians recognized il− h¢ aq as a distinct phenomenon.
The most obvious advantage that il− h¢ aq represented for the earlier grammarians is that it enabled them to reduce considerably the number of what we can describe as major morphological patterns that they had to acknowledge within a closed system.A quick look at the list of words that are said, in any grammatical work that includes them, to be appended to the word that represents such a pattern readily reveals the extent of this reduction.In the case of the major pattern faôlal, for example, Ibn al-Sarr¢ a" g (Uâ¢ ul, III, 182) gives " gaôfar and salhab as the noun and adjective that represent it and to which other words are appended.These words, the supposed radicals of whose roots are considered to be reducible to less than the four radicals of " gaôfar and salhab (see 2.2 above), are: − hawqal (fawôal), zaynab (fayôal), " gadwal (faôwal), mahdad (faôlal), ôalq¢ a (faôl¢ a), raô" san (faôlan), sanbata (faôlat or fanôal), 14 and 14 The final t¢ aé of the word sanbata(tun), of course, should not count in the proposed pattern, otherwise its inclusion under faôlal by Ibn al-Sarr¢ a" g would be inexplicable.He most probably included it under faôlal because sanbat is its variant (S³bawayhi,Kit¢ ab,II,348;cf. 327;101;Astar¢ ab¢ aOE d³,II,340).Faôlat is more likely to be intended by Ibn al-Sarr¢ a" g than faôlan (see Suy¢ uç t³, Muzhir, II, 15, for both possibilities) because the word after it, ôansal, represents fanôal, and Ibn al-Sarr¢ a" g systematically gives one ôansal (fanôal).The eight different patterns which these eight words represent were thus grouped together under one major phonological pattern, faôlal, since all of them conform to its wazn (metric measure), that is, its pattern of − harak¢ at and sakan¢ at (see 2.4 above).Similarly, hundreds of words are then cited by Ibn al-Sarr¢ a" g and grouped in such major patterns (ibid.,III,.15 Further reduction in the number of patterns is achieved by the grammarians' acknowledgement of the possibility of appending triliterals to quadriliterals that are, themselves, appended to quinqueliterals (Kit¢ ab, II, 341)-such as ôafan" ga" g (root ôF… G) which is appended to " ga− hanfal (root … G® HFL), itself appended to safar" gal (root SFR… GL)-and of deriving appended words from other appended words (Astar¢ ab¢ aOE d³, … S¢ ar− h, I, 55)-as ta" sayç tana, which is appended to tada− hra" ga and is derived from " sayç tana, itself appended to da− hra" ga.Understandably, the grammarians halted the process of reduction with words that are augmented quinqueliterals, such as qabaôà tar¢ a, simply because they did not find a six-radical pattern to which they could append them, and so there was no possibility of grouping words under major patterns (cf.S³bawayhi,Kit¢ ab,II,9;F¢ aris³,Baḡd¢ adiyy¢ at,122,434;Ibn … Ginn³,Munâif,I,51,and oe Haâ¢ aéiâ,I,Ibn ôUâf¢ ur,Mumtiô,I,206).
The grouping of appended words into major patterns gave the grammarians another considerable analytical advantage, namely, that they were able to draw up rules that are applicable not only to the words that represent the pattern and are not themselves appended to other wordse.g., " gaôfar and salhab of the major pattern faôlal mentioned in the previous paragraph-but also to all the words whose patterns are appended to faôlal-e.g., − hawqal, ôawsa" g, zawraq, hawda" g, etc., which are of the pattern fawôal, and zaynab, ḡaylam, âayraf, − dayḡam, etc., which are of the pattern fayôal, and so on.Such rules are abundant in the sources, as example for each pattern.
15 This grouping process which drastically reduces the number of "major" patterns is paralleled by the mostly Basran method of expressing augmented patterns, in most cases, by using only the letters f, ô, and l, in contrast with one Kufan method which allows the repetition of the same augments in the proposed pattern.Thus, safar" gal and " samardal are both represented as faôallal according to the first method, but as faôal" gal and faôaldal, respectively, according to the second.Obviously, the first method avoids generating an exceedingly large number of patterns and readily reveals the words that belong to the same pattern.See Suy¢ uç t³, Hamô, II, 213, for the differences among grammarians in expressing patterns; cf.F¢ aris³, Baḡd¢ adiyy¢ at, 529-31, and Astar¢ ab¢ aOE d³, … S¢ ar− h, I, 10-21.
early as S³bawayhi's Kit¢ ab.For example, S³bawayhi formulates a universal rule to the effect that all triliterals that were augmented to become quadriliterals and were appended to genuine quadriliterals have, like these quadriliterals, broken plurals of the pattern maf¢ aôil, such as " gadwal, ôià tyar, kawkab, tawlab, sullam, dummal, " gundab, and  ).In such lists, the grammarians group together appended words with the words that they are appended to and present each group as a homogenous category that shares several morphological traits applicable to all its constituents, irrespective of whether they are appended words or not.
3.3.The grammarians' use of il− h¢ aq as an analytical tool shows that they also employed it to achieve one of their principal goals-to limit deviations from the norm (qiy¢ as) and maximize the applicability of grammatical rules. 16The necessary condition for this purpose to be achieved, in the case of il− h¢ aq, is the existence of a closed and welldefined system that would unmistakably identify appended words and patterns and describe the rules to which they are subject.Once this is accomplished, words that do not conform to these rules can be easily disqualified from inclusion in the closed system.The mere fact that il− h¢ aq involves the condensation of several patterns into one major pattern (see 3.2 above) goes a long way towards reducing the examples to a more manageable number.Moreover, a sizeable portion of the corpus of appended words represents extremely rare usages which, after being appended to major patterns, become effectively part of the norm of their own class and, consequently, cease to stand out as extremely rare or solitary examples, as they indeed were prior to the classification process of il− h¢ aq.One such example is hammari" s (adjective for a very old and wrinkled woman; e.g., ôa" g¢ uz hammari" s), which repre-16 For a study of this principle and its effect on the pedagogical attainability of grammatical rules, see Baalbaki (forthcoming).It should be mentioned here that since our primary sources on il− h¢ aq are almost exclusively Basran, we cannot say for certain whether there was a partisan divide on the issue or not, but the methods which the Basrans use in this case largely reflect their general interest in interpreting data in a way that would restrict the existence of deviations.
sents a pattern faôôalil 17 described by S³bawayhi as qal³l (Kit¢ ab, II, 339) and which may be the only quadriliteral example of this pattern (Ibn Man− z¢ ur, Lis¢ an, HMR… S).Once this pattern is appended to a quinqueliteral word, such as qahbalis, " ga− hmari" s, and âahâaliq (Kit¢ ab, II, 341, 354; Suy¢ uç t³, Muzhir, II, 35), it becomes part of a larger entity and is no more regarded as anomalous.The same can be said of other examples usually cited as appended words, such as na› hwari" s, bulahniya, firind¢ ad, › hayzal¢ a, ôilwadd, and others.
Other techniques the grammarians employed in matters related to il− h¢ aq should also be seen in the light of their effort to limit deviation from the norm.S³bawayhi's treatment of q³q¢ aé and z³z¢ aé involves one such technique.Now these two words belong to the category of ism (noun), as opposed to maâdar (verbal noun), and so the word to which they are to be appended should also be an ism, in line with the regular distinction S³bawayhi-and the later grammarians-drew between ism and maâdar in their study of il− h¢ aq.The anomaly in the case of z³z¢ aé and q³q¢ aé, however, is that the pattern to which they should be appendedthe reduplicated biliteral of fiôl¢ al, i.e., *fiôf¢ aô, such as qilq¢ al-is used exclusively with maâdars (S³bawayhi, Kit¢ ab, II, 386; M¢ azin³, Taâr³f, II, 180; Ibn ôUâf¢ ur, Mumtiô, I, 151).To avoid this anomaly, which would affect the applicability of the distinction between ism and maâdar, S³bawayhi appends these two words to the nearest hamzated and unduplicated fiôl¢ al pattern (i.e., fiôl¢ aé) that does occur with isms, and chooses ôilb¢ aé to illustrate it.Another technique that ensures the widest possible application of qiy¢ as is the analogical extension of the rule (ç tard al-− hukm; see Astar¢ ab¢ aOE d³, … S¢ ar− h, II, 63) as applied to words whose derivation is not known.Thus, the y¢ aé of the appended word " gayéal, according to Ibn … Ginn³ (Munâif,I,35), can only be an augment in spite of the fact that the derivation of the word is unknown, because it can be demonstrated by examining other words that y¢ aé or w¢ aw can be one of the radicals (i.e., as opposed to augments) of quadriliterals only in reduplicated forms. 18 Similarly, Astar¢ ab¢ aOE d³ extends the rule through which the recurring con-17 In addition to this pattern, S³bawayhi refers to hammari" s in two other places as being of the pattern faôlalil (II, 341) and fanôalil (II, 354).Cf.Lis¢ an, HMR… S, where Ibn Man− z¢ ur attributes to S³bawayhi the proposal of two of these three patterns on two different occasions.See also Ibn ôUâf¢ ur, Mumtiô, I, 269, and Suy¢ uç t³, Muzhir, II, 29.
sonant is known to be an augment in a large number (kaà t³r) of words whose derivation is known-such as the appended words OE dura− hri− h, − hilibl¢ ab, and marmar³s, which he relates to their cognate triliteral roots-to those words whose derivation is not known-such as âama− hma− h and barahraha-and clearly says that he does so by way of analogy so that the rule might be applicable to all attested examples (faç taradn¢ a l-− hukm f³ l-kull; see … S¢ ar− h, I, 63).As a result, the rule's applicability is made to be universal rather than partial, and deviant examples become subject to the same rule that applies to the majority of the words of this type.
Turning to the identification of those words that do not qualify for inclusion in the closed system of appended material, it is clear that the grammarians not only strove to specify the characteristics of appended words so as to establish decisive criteria for the inclusion of material, but also dwelt on providing reasons for not including words that do not fit these criteria.As we saw earlier, particularly in 2.1-2.4,the grammarians specified the phonemes that may be used for il− h¢ aq and their positions within appended words, the number of radicals in these words as well as in the words to which they are appended, the major patterns into which they may be grouped, the nature of the relationship between the ziy¢ ada of il− h¢ aq and that of meaning, the formal (laf− z³) rules that apply to the derivations of these words, and the suspension of the rule of idḡ¢ am, where otherwise required, to them.Consequently, it may be said that any word that is at variance with any of these criteria cannot be part of the il− h¢ aq corpus.The following examples will demonstrate how nonappended words are identified by the application of these criteria and shed further light on the grammarians' use of il− h¢ aq as a morphological testing device.
a.The position of the augment.Several rules are mentioned under this criterion (Astar¢ ab¢ aOE d³, … I,[56][57]Hamô,II,.The hamza, for example, may be used for il− h¢ aq in medial and final positions, but in an initial position it cannot be an appending (mul− hiqa) augment unless it occurs together with another augment, referred to as mus¢ aôid (aid).19 Thus, whereas éalandad and éidrawn are considered to be appended to safar" gal and " girda− hl, respectively, because their initial hamza is accompanied by a n¢ un or a w¢ aw, éafkal, éublum, and éià tmid, whose initial hamza is the only augment, do not qualify as examples of il− h¢ aq.19 Astar¢ ab¢ aOE d³ (II, 56), however, states that he finds no good reason why an initial hamza may not by itself, without a mus¢ aôid, be considered mul− hiqa.
b.The number of radicals.As was pointed out in 2.2 and 3.2 above, words were excluded from il− h¢ aq on the basis of the number of their radicals.The most obvious case here is that of augmented five-radical words, such as ôa− draf¢ uç t, ôandal³b, qabaôà tar¢ a, and − dabaḡç tar¢ a. 20 Since there are no target words, i.e., six-radical words excluding any augment, to which these examples may be appended, the grammarians had to exclude them from the il− h¢ aq corpus and look elsewhere for possible interpretations.Hence, their explanation of the final alif in qabaôà tar¢ a-which they were also unable to explain as a feminine ending, since the word accepts n¢ unation and since the variant form qabaôà tar¢ at does include the feminine ending (S³bawayhi,Kit¢ ab,II,9,78,342)-as an augment of enlargement (takà t³r al-kalima) may be viewed as one way out of a difficult problem that arose because of the limitations of il− h¢ aq (cf. M¢ azin³,Taâr³f,I,51,and Ibn ôUâf¢ ur,Mumtiô,I,206).
c.The "target" pattern.In addition to the lack of a target pattern to which augmented quinqueliterals may be appended (see "b" above), several other words, and even whole patterns, were not considered to be appended because of the lack of a target word or pattern to which they can be appended.For instance, S³bawayhi (Kit¢ ab, I, 401-402) says that i− hmarartu and i" sh¢ ababtu, both of triliteral roots, are not examples of il− h¢ aq because there is no quadriliteral of the type *i− hra" gamtu or *i− hr¢ a" gamtu, respectively, to which they can be appended.M¢ azin³ (Taâr³f, II, 269) passes a similar judgment on iḡdawdana for lack of the type *i− hraw" gama, as does Mubarrad (Muqta− dab, IV, 3) with words like ôa" g¢ uz, raḡ³f, and ris¢ ala, which have no quadriliteral counterparts to which they can be appended.At times a whole pattern is said not to be intended for il− h¢ aq, as in the case of faôl¢ aé, for which there is no corresponding unhamzated pattern-i.e., a quadriliteral such as *sard¢ a− h or *sarb¢ al-to which it can be appended, and hence its two final alifs (i.e., ¢ a and é) are, according to S³bawayhi (Kit¢ ab, II, 10) and F¢ aris³ (Taôl³qa,III,38), used exclusively as a feminine ending.
d.The structure of the pattern.Contrary to "c" above, the target pattern may be available, but the structure of the words that can theoretically be appended to it prevent the process of il− h¢ aq.This may be illustrated by the pattern faôl¢ al, which theoretically is a target pattern to which triliterals may be appended, but no triliteral was appended to it 20 Cf. n. 7 above.The word − handaq¢ uq is usually mentioned with this group as well, but we did not include it because it is, as Ibn … Ginn³ rightly notes (Munâif, I, 53), of a quadriliteral origin, since its q¢ af occurs twice.
because its examples are restricted to reduplicated biliterals (hence *faôf¢ aô), be they nouns (asm¢ aé), such as zalz¢ al and " gaà t" g¢ aà t, or adjectives (âif¢ at), such as − haà t− h¢ aà t and − haq− h¢ aq (S³bawayhi,Kit¢ ab,II,338).The reason for this is that the structure of triliterals prevents the formation of reduplicated words, since this would theoretically require a nonexistent six-radical pattern.In comparison, the two sister patterns fiôl¢ al and fuôl¢ al were actually used as target patterns because their examples have four radicals that are not duplicated, such as qinç t¢ ar and qurç t¢ as, and therefore words of triliteral origin like " gilw¢ a› h and qurç t¢ aç t, respectively, lent themselves to be appended to them.
e. Meaning, derivatives and idḡ¢ am.The discussion of these three criteria in 2.3 and 2.4 above included several examples of words and patterns that were considered, in each case, to be outside the sphere of il− h¢ aq because they do not conform to the criterion at hand.

4.1.
As several examples cited above have shown, the various rules and details related to il− h¢ aq were used by the grammarians as a testing device for a host of morphological issues.So widespread was the practice that one may conclude that it represented for them a major objective, in addition to the principal objective of reducing the patterns within the closed system of appended words.Three of the most essential morphological premises they used il− h¢ aq as a testing device to check the validity of will be briefly discussed below.
a.The distinction between radicals according to aâl and ziy¢ ada.Appended words are used to confirm this distinction through the process of derivation and the realization of a common meaning they share with the roots.S³bawayhi (Kit¢ ab, II, 116), for example, argues that ôafarn¢ a (strong lion), because of its affinity to ôifr and ôifr¢ at (both also mean "strong lion"), is an appended word because of the ziy¢ ada of its n and ¢ a, and he shows how this ziy¢ ada-as well as that in ôuf¢ ariya, which likewise means "strong lion"-is reflected in various aspects of their morphology.This is further tested by the four diminutive forms ôufayrin, ôufayrina, ôufayr, and ôufayriya, the first two of which prove that the ¢ a of ôafarn¢ a is z¢ aéida, whereas the other two prove that its n¢ un is z¢ aéida.In this particular case, appended words are used to check the validity of the morphological rules that govern the diminutive and that are largely based on the distinction between what is aâl and what is ziy¢ ada in the words from which diminutives are formed.
b.The assignment of the position of the ziy¢ ada.Since appended words mirror the phonological construction of the words that they are appended to, including the positions of what is aâl and what is ziy¢ ada, they were used by the grammarians to check the correctness of the roots that they assign for augmented words.An example of this are the two words i− hran" gama and i› hranç tama, said by the grammarians to be quadriliterals (ban¢ at al-arbaôa) because they interpret the n¢ un as an augment (cf.M¢ azin³, Taâr³f, I, 86).This interpretation is supported by the comparison some grammarians make (ibid., I, 86-89, and Ibn … Ginn³'s commentary) between these words and appended words such as iqôansasa and islanq¢ a, the maw− diô (position) of whose augmented n¢ un is determined to be between the ôayn and the l¢ am, i.e., the second and third original radicals of the roots QôS and SLQ, respectively.It may thus be said that the two types of words reciprocally support the grammarians' interpretation of each of them.
c.The identification of inadmissible patterns.The problem of identifying what is permissible and what is not seems to have occupied the earlier grammarians and lexicographers, probably as part of their effort to uncover the rules that determine the structure of Arabic words and consequently to be able to recognize as Arabicized or invented any word that is inconsistent with these rules. 21In this respect, the grammarians proposed several unattested patterns of il− h¢ aq which violate accepted structures in order to show that their impermissibility is due to the impermissibility of their counterparts to which they would have theoretically been appended.Ibn … Ginn³'s (Munâif, I, 88-89) masterly discussion of why patterns of the types *ifôanwaltu, *ifôanlaytu, *infanôaltu, *³fanôaltu do not occur reveals that these were proposed to demonstrate their incompatibility with the attested pattern ifôanlaltu, as in i− hran" gamtu, to which augmented quadriliterals are usually appended (Suy¢ uç t³, Muzhir, II, 41).Furthermore, the grammarians' discussion of the criteria that disqualify words from being considered as examples of il− h¢ aq (see 3.3 above) shows how they repeatedly use them to check the validity of the rules that determine the permissibility or otherwise of target words and patterns to which other words and patterns may be appended.
The use of il− h¢ aq as a testing device nowhere finds it ultimate applica- The earliest attempt of this kind is probably oe Hal³l's introduction to Kit¢ ab al-ôAyn, written in the second half of the second century A.H. In it, he discusses some of the phonetic characteristics and phonotactics of Arabic words (I, 52-55) and specifically cites examples whose phonetic structure betray their foreign origin (e.g., duô" s¢ uqa and " gul¢ ahiq) or their invention by skillful scholars (na− h¢ ar³r; e.g., ka" saôà ta" g and › ha− daôà ta" g).See also Baalbaki 1998, 52-53, Sara 1991, 36-38, and Talmon 1997, 137-38.tion better than in what is known as mas¢ aéil al-tamr³n (drill problems or exercises).Such drills are not only intended as pedagogical devices to train students and examine their grasp of the concepts involved.More essentially they test the applicability of these concepts through increasingly difficult questions, the answers to which should be in compliance with the theoretically permissible structures of Arabic words and patterns. 22Indeed, Ibn … Ginn³, in his justification of M¢ azin³'s lengthy chapter dealing primarily with il− h¢ aq material and entitled "Analogically formed unsound words the only patterns of which are used in sound words" (h¢ aOE d¢ a b¢ ab m¢ a q³sa min al-muôtall wa-lam ya" gié mià t¢ aluhu ill¢ a min alâa− h³− h; Taâr³f, II, 242-323), says that the reason for the invention of this "science" (ôilm) is to use attested material as the basis for analogically constructing unattested material.By so doing, the grammarians could confirm the soundness of the morphological postulates that they used to explain attested usage.In M¢ azin³'s chapter, for example, the rules governing the use of w¢ aw and y¢ aé, known as iôl¢ al, are thoroughly checked by arbitrary formulations such as *ibyayyaôa, *uqw¢ uwila, *iwéawé¢ a, *³w³w¢ aé, and ḡazwaw¢ ut (II,243,245,247,251,257,respectively).The fact that each of the questions which usually begin with the stereotype expression "Construe (ibni) x from y" should have one correct answer shows how the sum of rules that the grammarians deduced from usage worked together to yield attested words as well as theoretically usable words.Among the rules these drills seem to test in relation to w¢ aw and y¢ aé are the effect of vowels on them, the shift from one of them to the other, their compatibility and incompatibility, and principles related to gemination, omission, and their relation with hamza.
4.2.On a wider scale, the grammarians were keen to incorporate il− h¢ aq into their overall system of grammatical analysis and to demonstrate its pertinence to it beyond the morphological level.It is for this purpose that they try to show how some of their assumptions and general principles of analysis are harmonious with their approach to il− h¢ aq.An example of this is the principle that if a word is characterized by à tiqal (heaviness), the 22 These drills are comparable to the grammarians' practice of converting complex sentences into relative structures.The aim of this process, known as i› hb¢ ar (predication), as Carter (1981, 353) correctly argues, "may well have been to transform all utterances into propositions in order to test their truthfulness," but it "finished up as a mere pedagogical device."Likewise in the case of our drills, their pedagogical purpose has eventually gained supremacy over their use as a device for testing morphological rules.not feature in actual usage but have the force of what is uttered (f³ − hukm al-malf¢ u− z).This is similar to the claim of the grammarians that some nouns, such as the interrogative particle m¢ a, resemble supposed, non-existent particles that the like, and that it operates according to well-defined rules that exhibit a logical relation among appended patterns (cf.Kit¢ ab, II, 401, where S³bawayhi establishes the following correspondence: faôall: faôlal = fuôull: fuôlul = fiôill: fiôlil; and Ibn … Ginn³, Munâif, I, 47, where the relation between quinqueliterals and quadriliterals is said to be the same as that between quadriliterals and triliterals).Ultimately, perhaps, the grammarians wanted to demonstrate that il− h¢ aq is yet another proof of the underlying logic of language and to stress that it is the grammarian's task is to discover the various ways in which this logic expresses itself.
