The topic of the paper is a small group of Norwegian dialects where lenition of p, t, k into b, d, g in intervocalic and word-final position is limited to words characterized by a monomoraic, stressed syllable in Old Norse. These dialects are spoken in the easternmost local communities in Agder county, at the eastern margin of the South-Norwegian lenition areas where lenition hit all short oral stops irrespective of preceding vowel length. After the quantity shift had made all stressed vowels bimoraic, with rimes being either VV or VC, the distribution of the lenited plosives are after both long and short vowels (the main area) or after short vowels only (the eastern marginal area).
Haslum (2004) argues that the limited distribution in the east ist the result of a reversal after long vowels only. While this cannot be refuted as a possibility, I argue below that it may also be the result of a two-stage process, whereby lenition after a short vowel has spread further than the generalized process.
