A sound like /ö/, namely a mid front or central rounded vowel, appears in the inventories across dialects contigently. A particular potential source for it is a realization of phoneme /â/ before a labialized consonant. Overall, reconstruted a in *CaCʲ, which we denote by /â/, can realize in a variety of centralized vowels, like ɜ, ɞ, o, ö, ɨ, aˁ, ä and a. Here we measure all the possible inter-dialectal correspondences between the first vowel in cognates of Rutul /ekul/ 'nest'. The sounds in check (preliminary values) are the last vowels. In this feature, ä / e / aˁ / ɜ are grouped together as e-like (I noticed ɜ as a correspondence of â in some dialects) and values ö / o / ɞ are grouped as ö-like.
