From a systemic linguistic perspective, the DynAT research area “Lexical and Grammatical Variation and Change” focuses primarily on the linguistic levels of lexis and grammar and their intersections. Research interests include phenomena of lexis (vocabulary) including word formation, inflectional morphology as well as multi-word expressions, syntactic constructions and phenomena on the intersection of syntax and semantics. The theoretical paradigms in which these lexical and grammatical analyses are embedded include variationist linguistics and sociolinguistics as well as research on standard language, dialectology, language change, language history, language attitudes and cognitive linguistics.

The following sub-projects contribute to the DynAT research area "Lexis and Grammar in Transition":

• WBÖ – Lexicographic Documentation of 20th-Century Bavarian Dialects 

• Lexicography meets AI 

• Austriacisms – AMC meets Variationist Linguistics

• Standard Language in Austria – Lexicographic Cooperations 

• LexAT21 – Atlas on lexical variation in Austria in the 21st century 

• ASR meets Historical Dialect Data

Cooperation/Satellite projects 

The following externally funded projects, which are situated in the context of the research unit Linguistics of the ACDH or which are cooperation projects (with external PI) working with the research unit, are closely linked to the DynAT activities and contribute significantly to the research on lexical and grammatical dynamics in Austria:

• BASyQ – Bavarian Dialects of Austria and South Tyrol in the 20th Century – Quantitative Analyses Based on the WBÖ Corpus (FWF 10.55776/PAT1009925; PI: Philipp Stöckle) 

• LexVAD20 – Lexical Variation of Austrian Dialects in the 20th century (FWF 10.55776/PAT1412824, PI: Alexandra N. Lenz)
