It deals with the question what aspect is and how it can be defined, what types of aspect there are in different languages of the world, what the distinction is between verbal aspect and lexical aspect, and what the relation is between aspect and tense. The article also pays attention to aspect as a crosslinguistic category, and aspect as a language-specific category.
