This book addresses some methodological problems in the study of tense, aspect and action: How should linguists go about describing these categories and with what terminology? How does our work in this area relate to descriptions of language(s) in general? What research strategies should be explored? Bache discusses the interaction between language-specific grammars and universal grammar, including the problems of analytic directionality, semantic minimalism, and the general metalanguage of universal grammar. The book has several sources of inspiration: generative linguistics, structuralist phonology, glossematics, functional grammar, cognitive semantics and prototype theory. Bache argues strongly for the inclusion of a paradigmatic dimension in the study of the semantics of morphosyntactic categories. Rather than adhering to one particular linguistic school, Bache provides a general description of tense, aspect and action in the form of generalizations that should be accommodated in any theory.
