Iambic effects and Cliticization in Pacoh
As a Mon-Khmer language of the Katuic subgroup,Pacohdisyllabic word structure is typically ‘sesquisyllabic’. First syllables are unstressed and restricted in phoneme inventory. Although CV main syllables have a choice of 18 vowels, CV presyllables are limited to /a, i, u/. Although CVC main syllables have a choice of 30 vowels, CVC presyllables are limited to schwa and final C of a nasal or liquid.Although there is a tendency in Mon-Khmer toward monosyllabicity, Pacoh is noteworthy in having a large number of disyllabic words and more prefixes than most. However, some forms that were previously labeled 'prefix' (Cf. S.Watson, M. Alves) are better identified as 'clitics'. The same iambic effects that characterize presyllables and prefixes have contributed to several free words developing clitic forms that only occur before monosyllabic roots. The same iambic effects involved in grammaticalization effect both clitics and affixes (Cf. Keller and Gregerson).
If iambic effects coupled with head-initial word order contribute to formation of clitics in Pacoh, why do we hear so little of clitics in Mon-Khmer languages? If the free forms are required to precede two syllable words can clitics ever fully grammaticalize?
