Foot-based allomorphy in Tlapanec (Mè'phàà).

Under the P» M model, the generalization is that the glottal stop can only be realized when the stem is monosyllabic (as well as other phonological factors, such as the presence of a lexical glottal stop in the stem and if the stem begins with a cluster or not). The prosodic word in Tlapanec can consist simply of a stem, a stem + an affix, or possibly stem + stem compounds. Recall that the alternation was between the allomorphs I gita i - and I gi - i , the former occurring with disyllabic stems, while the latter with monosyllabic stems; with the latter, the glottal stop is deleted before a stem-initial consonant cluster or when the stem contains a glottal stop.

Lastly, the 3 sg agent prefix has a glottal stop when the stem is monosyllabic (3b) while this glottal stop is not found when the stem is disyllabic, as in (3a). [Extracted from the article]
