About constructions with auxiliaries in Polotsk charts of the 14<sup>th</sup> -16<sup>th</sup> centuries
This article is devoted to the functioning of auxiliaries in Western Russian documents - Polotsk charts of the 14th-16th centuries. During this period, auxiliaries begin to actively compete with their full-stressed variants - personal pronouns, so special attention is paid to the distribution of constructions such as participle + pronoun and participle + auxiliary. It was found out that the model including both auxiliaries and pronouns was used in live speech and was one of the variants of the development of perfect forms in the West. In this paper, we also consider patterns where auxiliaries, being a complete synonym of pronouns, are used as a personal numeric mark for past verbal adverbs.
