This article is the first fragment of a linguistic study on the antroponymy of the Sangerei onomastic area. Designed as a dictionary, the study reflects specific aspects of the subject matter of the study: the etymological and derivational structure of family proper names, the lexical meaning of origin and further onymyc, geographical distribution by localities, first documentary attestation, directions and ways of spreading the onymycs in Romanian antroponymy. On the basis of synchronic and diachronic research of the repertoire of names there was established that antroponymy of Sangerei onomastic area is characterized by linguistic peculiarities common with that of any Bessarabian area and with that of the Romanian onomastic system in general.
