In this monograph, the perspective of studying the content formation of the syntactic structure and its semantic development within the framework of cognitive and functional grammar directions of modern linguistics is defined, the separation of lexical-semantic and grammatical means of expressing the meaning of result is determined by the possibility of using linguistic units in the functional-semantic field. In addition to the categories of grammatical tone and tenses, aspectuality studies action groups of verbs (dynamic, static, limited, non-limited) and their subgroups, i.e., beginning, duration, completion, iterative, perfective, transitive, resultative, expressed in the term actionsart (mode of action). At the same time, it investigates the difference between the components of the context that affect aspectuality, expressed using lexical and syntactic means that do not involve the verb.
