This article deals with the study of Armenian anthroponymic system, particularly, with the morphological structure and etymological semantic of proper names. The aim of this article is to explore derivative models of proprial word formation in order to show the transformation of lexical units and grammatical units into proprial word formation morphemes. The question of interpretation of morphological structure of foreign proper names becomes actual by their rendering in other languages. A common rendering difficulty is caused by almost lack of any explicitly grammatical gender designation in Armenian personal names and surnames. Commen suffixes serve as proprial signals.
