Temporal architectonics of dialects: word-formation aspect (exemplified by vocabulary of Transbaikal old believers’ dialects)

The article deals with the dialects of Transbaikal Old Believers (Semeiskie). We consider lexical and word formative archaisms of Proto-Slavic origin, which are characterized by preservation of ancient morphemic composition. This group includes chronologically marked lexical units of three types: words that differ from the corresponding literary words by presence of other affixes, old derivating words with derivative formations as analogue in literary language, and ancient derivatives. The study of lexical and word formation archaisms as the fact of language structure suggests distinction of archaic vocabulary from the historical variants of Proto-Slavic lexical phenomena, which are not reflected in the modern literary language. These archaisms we refer to dialect vocabulary of Proto-Slavic origin, they have changed (lost, substituted, derived) suffix (prefixed tumors in the dialects of Transbaikal Old Believers have not been found) in Old Russian (and later) periods of language development. Proto-Slavic reconstruction, which goes back to the word, is continued by unchanged literary correspondence.
