A Reviewed Study on the Phonological Phenomena of the Stem Final ‘h"

&nbsp;&nbsp;In the conjugational form /noh+n？n/→[nonn？n], the phonological process like ‘h→n’ was simply explained as a kind of nasalization coventionally on the basis of a syntagmatic relation of their constituents. The result of ‘n’ in the change ‘h→n’ can directly be derived either by the regressive assimilation to the following nasal sound or by the way of the syllable final neutralization to the alveolar ‘t’ or glottal ‘？’. Moreover it has recently been explained by autosegmental spreading a nasal feature to the empty slot which was produced after deleting ‘h’ and also by the interaction of faithfulness and alignment constraints in the OT.<BR>&nbsp;&nbsp;However these previous explanations do not seem to be satisfactory and also do not resolve many problems because their process is unnatural phonologically. Therfore I suggest a new approach on the basis of its prosodic structure. In the view of prosodic points, the change ‘h→n’ will be explained by the gemination of following initial nasal consonant of endings. The phonetic features of laryngeal spread ‘h’ and the mora projection at the level of sentence phonology will have to profoundly be considered in order to understand this phonological phenomena completely. Moraic ‘h’ at the coda has to be licensed by the root node whithin its Feature Geometry. However as this ‘h’ does not have the root node originally, the mora of preceding heterosyllabic coda have insted to govern the following initial consonant of the endings and then gemination will appear.
