The present paper aims to explain the morphological opacity between vrăh (singular form) and vărhove (plural form) ‘peak’ in Bulgarian. Adding a plural suffix -ov- causes a change in the syllable structure of vrăh into vărh-, which is an irregular phenomenon. In order to explain the phenomenon, we not only adapted the Sonority Dispersion Theory, but also examined the respective diachronic phonological changes and the dialectal situation in Bulgarian. Although, according to the Sonority Dispersion Principle, the change of vrăh into vărhove is not optimal, vărhove still appears as a surface form; i.e. sonority is not the main factor of this alternation. Apart from that, the present study analyses the diachronic change of the liquid and the reduced vowel. We claim that there exists a connection between the vrăh – vărhove phenomenon and the phonological feature of syllabic liquid r and l in Old Slavic and resyllabification.This work was funded by Hankuk University of Foreign Studies Research Fund of 2015.
