Theo Vennemann

Theo Vennemann genannt Nierfeld (; born 27 May 1937) is a German linguist and philologist. He is an emeritus professor of Germanic and theoretical linguistics at LMU Munich.

Vennemann has published on phonological theory, historical linguistics, and models of language change. His early work in phonological theory includes contributions to Natural Generative Phonology, and his later publications have influenced discussions of language change through his concept of linguistic preference laws.

Since the 1990s he has also advanced hypotheses about prehistoric language contact in Europe, including proposals involving a Vasconic substratum and Afroasiatic influence, which have been debated in historical linguistics.

Career Vennemann was born in Oberhausen-Sterkrade in Western Germany. Preference laws became a central element of his work from the 1980s onward.

Selected works Preference Laws for Syllable Structure and the Explanation of Sound Change (1988). Europa Vasconica – Europa Semitica (2003).
