The Otsop dialect (Otsop-Horsa), to some extent, stands out among the closely related dialects of the Jauk-Vayk interdialect (about a dozen villages of the Vayots Dzor marz of the Republic of Armenia). Phonetic, morphological and lexical deviations of the Otsop dialect from the general features of the interdialect can be explained not only by contacts with the neighboring dialects (Artsakh-Syunik dialect, interdialect of Northern Goghtn), but also by the fact that in the first half of the 19th century Armenians who migrated from Khoy and Salmast moved to the village of Otsop and lived together with the local residents, whose native dialect left its mark on some features of the autochthonous dialect.
