Grammatical gaps: definition, typology and theory

Grammatiken sind (metaphorisch gesprochen) Anweisungen zum richtigen Gebrauch einer Sprache. Interessanterweise zeigen Grammatiken offenbar Lücken, die dadurch entstehen, dass für bestimmte Bereiche Regeln (bzw. Formen) ganz fehlen oder dass sich einzelne Regeln widersprechen und der daraus resultierende Konflikt deren Anwendung verhindert. Grammatische Lücken, auf deren Relevanz für eine ''realistische'' Grammatiktheorie wohl zuerst Marga Reis hingewiesen hat, sind in den letzten Jahren schon vereinzelt in den Fokus der Forschung geraten. Das Sonderheft versammelt Arbeiten zu verschiedenen Arten von Lücken und zeigt damit, wie ertragreich und wichtig die Erforschung grammatischer Lücken sein kann.Grammars are (metaphorically speaking) instructions for the correct use of languages. One might expect that grammars are complete, i.e., that they provide an appropriate solution for each utterance context. Interestingly, however, grammars seem to show gaps, which are caused by the fact that rules (or forms) in certain domains are missing completely or that individual rules contradict each other and that the resulting conflict prevents their application. Grammatical gaps, whose relevance for a ''realistic'' theory of grammar was probably first pointed out by Marga Reis, have come into the focus of research in recent years. The present special issue collects papers on different kinds of gaps and shows how fruitful and important the investigation of grammatical gaps can prove to be.Inhalt:Introduction– Ralf Vogel: Grammatical gaps, grammatical invention and grammatical theory– André Meinunger: Unexpected finite verb forms in German – cases of grammatical illusion?– Patrick Mächler, Anja Hasse: Gaps of definiteness.
