Changes of Phonological Process in the transition from Pahlavi Language to Laki

Laki is one of the remaining dialects of the Pahlavi language and most of its speakers live in Lorestan, Kermanshah, Ilam and Hamadan. While time passing, words usually experience transformations in their structure. Laki language in transition from Pahlavi has also been changes in phonemes and words. The aim of this study is to investigate the process of phonological changes in the transition from Pahlavi to Laki languages, and the position and method of phonemes expressing in terms of common words change and it tries to answer these questions: 1) what are the phonemes changes in the transition process from the Pahlavi to the Laki? 2) Have the position and manner of articulation of phonemes had a role in the change of other phonemes? Consequently, phonological changes in the transition process from Laki to Pahlavi have been five processes of decreasing, increasing, relocation, merge, and change. Meanwhile, variations in the change of process are more than others. Phonological decreasing is in the beginning, in the middle and at the end of the words. Phonemes relocation exists only between a-r and a-s phonemes. It can be said the position and the expression method of phonemes have had effective role in phonemes change based on the statistics of this research. The procedure in this paper involved extracting common vocabularies from Pahlavi dictionaries and comparing them with Laki vocabulary items.
