Комментарии: The initial nasal in Av. (n- or m- in different dialects) is not quite clear etymologically. The original meaning of the morpheme ('behind') is preserved when it functions as an adverb; but as a locative suffix it had early (as early as Proto-Av.-And.) merged with another morpheme, PEC *-q̇_V (q.v.) and thus acquired a new meaning 'at, by, close to'. In most Andian languages this meaning is preserved until now (only in And. proper the meaning of -q:i changed: it is now confined to the plural inessive /haq̇:o-ba-q:i 'in the houses'/, and in singular is used to denote an object of verba dicendi or an inanimate ergative). The merging of *-q:i and the hypothetic *-q̇:i ( < *-q̇_V) was possible because of the phonetic affinity of the morphemes, but also because *-q:i must have also had an early additional possessive meaning ('at, by someone or smth.'), which is characteristic for most Andian languages and is observed also in the Lezgian counterpart *-q(a).
