To the Sources of the Bulgarian Words in the Bulgarian Etymological Dictionary

The article deals with the origin of the Bulgarian vocabulary according to the multi-volume Bulgarian etymological dictionary, one of the main nationally signiﬁcant projects of the Institute for Bulgarian Language at the Bulgarian Academy of Sciences. In summary, it presents the different chronological and genetic layers of vocabulary that build the Bulgarian language. The two main layers of vocabulary are emphasized - the original Slavic and the later Balkan layer, which characterize the language as both Slavic and Balkan. The classical (literary) Old Church Slavonic source is pointed out, as well as other older and new foreign sources and the different ways of penetration of the lexical units into the literary and colloquial language and in the Bulgarian dialects are revealed.
