Abstract
The article deals with the analysis of the semantic changes in the vocabularies of the Russian and Azerbaijani languages caused by the influence of the different factors. Semantic archaisms are systematized according their belonging to the concrete part of speech (nouns, adjectives, verbs) and given in the appropriate tables. The reasons of the semantic changes during the historical development of the language are explained.
Some Russian semantic archaisms are still used in the other Slavic languages (Ukrainian, Polish, Serbian). The historical excursus is carried out in the article, as necessary.
So though the meanings of the Russian and Azerbaijani words considered in the article are archaic they are preserved in the structure of the modern words and might be relevant to the specific fields. They are used as terms in the different fields of science, they are preserved in the dialects, folklore. They are also important components of idioms, proverbs, sayings as they are relics of the past retained in the modern Russian and Azerbaijani languages. They have their own characteristics that makes them unique lexical items.
Research of such semantic changes caused by the different factors is very interesting and significance both from the linguistic and historical standpoints.
