Syllable Structure

This article provides an overview of natural phonological processes in the dialect of Sistani Persian spoken in Iranian Sistan, and reviews theoretical implications of these processes. A representative selection of processes in the language is examined in reference to conditioning by surrounding segments and conditioning in reference to syllable structure. While assimilation and dissimilation are tied to segmental context, deletion, epenthesis and metathesis are considered in light of syllable structure requirements. Synchronically, natural processes include those that are of an allophonic nature as well as those which involve morphophonological alternation. The description of these phenomena is corroborated by a discussion of the application of natural processes in diachronic changes. The authors show that, in some cases, the Sonority Sequencing Principle (SSP) is violated in Sistani Persian. This phenomenon is attributed not to language-internal factors, but rather to the generalization of marked structures as a result of interference from Standard Persian.

Evolution of languages has always been of interest to linguists. In this paper we study the natural progress of the syllable structure from Old Persian (O.P) to Middle Persian (Mi.P) and up to the Modern Persian (Mo.P). For this purpose all the words containing consonant sequences are collected from specific sources of each of these languages, and then analysed according to the syllabification principles. Pulgram (1970) distinguishes three principles for this matter which is stated in Hyman (2003:279).The first one, is the maximum open syllable principle, the second, the minimum coda and maximum onset principle and the last one is the irregular coda principle. In addition , to find the syllable structure of the words, phonological rules are also applied. Greenberg (1978) suggests a number of rules specifying the collocation constraint of phonemes and phonological structure of the word, which are: Obligatory Contour Principle (OCP), Sonority Sequencing Principle (SSP) and Syllable Contact Law (SCL). On basis of these rules and principles the clusters are separated from sequences, and the syllable structure of each language is acquired. Finally the progress of the syllable structure change is studied through representing the data from all three languages, and investigating the process taken for clusters to reach the present time. As the data exhibits, in O.P initial consonant clusters are frequently observed and also, through syllabification, some final syllable clusters will be obtained. In Mi.P also both initial and final clusters fully exist, with growing number of final ones. Initial consonant clusters are completely omitted in Mo.P and only final clusters remain. Deletion and vowel insertion are the two most occurring processes in these processes.

The present article dedicates to studying the syllable-internal structure in three Iranian Balochi dialects (IBDs) namely Mirjaveh Sarhaddi, Sarawani and Lashari dialects. The data analysis will be based on the onset-rhyme theory (e.g., Kurylowicz, 1948; Fudge, 1969; Vergnaud & Halle, 1979; Selkirk, 1982). Moreover, the syllable weight in IBDs will be discussed in the framework of mora theory (Hayes, 1985, 1989). The data have been collected during the research fieldwork in Sistan and Baluchestan province, Iran. The research findings demonstrate that the Balochi language is an example of a nucleus-weight language in which heavy syllables depend on the number of elements in the nucleus. Thus, CV and CVC are light syllables and CVV(C) syllable is counted as heavy syllable. Besides, the context-dependent weight of CVC syllables occurs in IBDs stress pattern system. Studying the syllable contact (word-medial consonant clusters) in IBDs shows that Balochi is among languages that admit all types of heterosyllablic clusters.
