A Typological Analysis of Rounding Harmony in Turkish Varieties of Razan, Tabriz and Istambulion the basis of Korn's Typology

The present research is focused on investigating the coverage of categories of Korn's typology as well as the existing symmetry or asymmetry in rounding harmony within Iranian (Razan and Tabriz) and Istanbuli varieties of Turkish. The main research questions are as followed: 1. Can the Turkish varieties be classified within Korn's categories or additional categories are to be added therein? 2. Is there a symmetrical system in rounding harmony in the varieties under consideration? The research results demonstrate that in spite of the similarities observed within the syntactic, morphological and … areas of the three varieties, within their photological areas differences are detected, according to which the three systems can be classified in triple hypothetical categories of A, B and C. Among which only the Razan variety illustrates a total symmetry in front and back vowels in transmitting roundness.
