This series publishes original contributions which describe and theoretically analyze structures of natural languages. The main focus is on principles and rules of grammatical and lexical knowledge both with respect to individual languages and from a comparative perspective. The volumes cover all levels of linguistic analysis, especially phonology, morphology, syntax, semantics, and pragmatics, including aspects of language acquisition, language use, language change, and phonetical and neuronal realization.

Grammatical structures connect systems of thought and articulation, the conditions of which hardly seem to fit each other. Repairs are productive mechanisms that solve translation problems between modules or levels by adapting derivations or representations to requirements that have to be met unconditionally. Compensating for derivational and interpretive defects, repairs determine core properties of natural language grammars and their interfaces.
