The research group Diachronic and Diatopic Linguistics (DIALING) carries out research in the field of historical and diatopic linguistics. The research contributes to these disciplines by (i) language description and documentation through the creationand dissemination of various types of descriptive tools (e.g. dictionaries, grammars, corpora, text editions, databases, etc.) and by (ii) the advancement of linguistic theory, which is informed by empirically-grounded studies. Diverse theoretical viewpoints on language variation and change (e.g. Construction Grammar, Cartography, Dynamic Syntax, etc.) are explored for the genesis and development of a variety of linguistic phenomena.
