Pskov word in diachronic aspect (recalling Ignatiy Yagich's traditions)

The literary legacy of the renowned researcher Ignatiy Yagich is crucial for verification of modern philology trends' compliance with the precepts formulated by this Slavonic scholar. The aim of the article is to acquaint readers with traditions of Larin's lexicography school on the example of the Pskov Regional Dictionary Containing Historical Data. A method of complete material sample, methods of linguistic geography and ethnic linguistics, as well as descriptive and comparative methods contribute to a substantiated representation of the dialect worldview in synchrony and diachrony. The article demonstrates how detailed and elaborate systematic description of the words in modern and historical parts of the dictionary entries provide valid data about various levels of the folk language. As a result of lexicographical research, the formation pathway of certain folk words was revealed; the family of words with весн- base were detected. With the help of the historical part of the dictionary it was found out that the word весна had two professional meanings characteristic of Pskov region (none of the historical dictionaries provide such information, but the Pskov Court Letter does). Thus, a research and presentation of the words in synchronic and diachronic aspects correlated with extralinguistic facts are key factors to a solution of practical and theoretical problems related to lexical and grammatical (even sometimes phonetic) nature of a folk word.
