Chronologically marked vocabulary in the dialects of Transbaikalian Old Belivers

The article analyzes Slavic vocabulary in the dialects of Transbaikalian old believers. There are different chronologically labeled layers in its composition. Special attention is paid to very ancient words, going back directly to proto-slavic epoch. The studied archaic linguistic phenomena structurally induced, which allows to classify the material and to highlight a different kind of archaic dialect vocabulary. The paper examines the lexical-phonetic archaisms of proto-slavic origin, characterized by the preservation of the ancient sound of the composition. This chronologically-marked group includes lexical units of two types: it has preserved the proto-slavic sound structure (in this case a transformed phonetic version corresponds to them), the other type consists of lexical-phonetic archaisms, which continues one of two (or more) of likely proto-slavic versions, the second of which continued the literary word.
