Из наблюдений над семантикой имперфективного будущего в среднерусской письменности

The present paper investigates differences between the semantic types of predicates which occurred in the constructions with the auxiliaries budu and stanu in Middle Russian. The data for the research was collected using the Middle Russian part of the Russian National Corpus. The examples in the final dataset were classi fied according to the date, source, and semantic type of the verb used in the constructions in question. The study has shown that states were more likely to co-occur with the auxiliary budu, whereas accomplishments denoting the accumulation of effect — with the auxiliary stanu. Such differences between budu and stanu show that budu was not a simple “foreign” replacement for stanu but penetrated the verb system through a separate set of contexts not related to expressing inchoative meaning.
