This chapter provides a basic overview of how verbal aspect functions in the Russian language. English does not have aspects, but the concept is familiar. Verbal aspect in Russian demonstrates when the action of a verb occurred, either in the present or the past. This chapter focuses on recognizing the differences between the usage and formation of imperfective and perfective verbs. You will learn useful prefixes, suffixes, adverbs, temporal expressions, and basic verbs of motion. At the end of the chapter, you will apply your knowledge of verbs of motion to the accusative and dative cases.
