The central question of this project is whether it is possible to put grammatical systems on geographic maps instead of individual linguistic properties and if so, how this geographic variation can best be modeled theoretically and be visualized. The project has four subprojects: (i) Inclusion relations (PhD project) which looks at implication relations between morphosyntactic properties that correspond to geographic inclusion patterns; (ii) Transition zones (PhD project) which investigates the (morpho-)phonological properties of grammars in transition zones; (iii) Computing regions (postdoc project) which investigates how linguistic regions can be computed quantitatively and visualized; (iv) Grammaticometrics (PhD-project)which aims at modeling variation between grammars and visualizing this.
