Over the past thirty years, there has been growing interest in aspect, not somuch in traditional Romance research but rather in typological studies. Here,there has been intensive and increasing concern with the combination of those grammatical verbal categories that are often realised by morphological syncre-tism in many of the world’s languages, the so-called TMA categories: tense,mode and aspect. Emphasis has repeatedly been laid on tense and aspect assystems complementary to the temporal categorisation and structuring of statesof affairs, stressing their close connection.4Meanwhile, studies of the lexicallyexpressed category ofAktionsart, related to aspect in terms of content, becamemore frequent and more precise. The question, in particular, of the semanticsimilarity between these two categories has been repeatedly discussed and in-vestigated. In research on aspect, this has raised various questions that haveopened up new avenues of investigation.
