ENIt is argued that, contrary to what is claimed in a series of relatively recent studies, verbal aspect has acquired the status of a grammatical feature in Baltic, and the notion of grammatical aspect is relevant to the description of the Baltic languages. As is widely recognized, aspect is less grammaticalized in Baltic than in Slavonic, but the difference is one of a degree rather than of essence, as in both language branches grammatical aspect arises from the grammaticalization of lexical aspect classes.
