Infinitival constructions (ICs) have received considerable attention from syntacticians and typologists, but less so from variationist linguistics. Based on new data from a comprehensive dialect survey, this study investigates the variation and change of ICs in Austrian dialects. The results reveal clear geographical patterns for different IC variants in Austria. Regarding linguistic factors, several constraints are identified, most importantly with respect to the IC’s syntactical function and governing element (e.g., phase verbs). Moreover, an apparent-time analysis shows that one variant (zum + infinitive) has been grammaticalized and spread at the expense of all other variants, presumably due to both dialect leveling and dialect-standard advergence.

This article presents computer supported “language production experiments” (LPEs) as a method for the investigation of syntactic variation. It describes the setup for the investigation of numerous syntactic phenomena and provides a sample study of the German GET passive across Austria. It also suggests that LPEs offer possibilities for the targeted investigation of linguistic variation in various ways. They may be used to explore speakers’ individual linguistic repertoires and an according corpus setup can be used to examine e.g., interspeaker patterns of variation. LPEs also enable researchers to investigate which linguistic factors control or influence syntactic variation.
