Abstract
On the basis of authentic corpus material, the study provides evidence that adequate grammatical description of spoken Czech, as attested in informal interaction, must also include the category of non-propositional dative. While maintaining a connection with propositional datives through the persistent semantic feature of indirect affectedness, this interactional category displays a range of non-propositional meanings based primarily on expressing a subjective stance and attending to interpersonal relations.
The study is grounded in a specific theoretical and methodological approach, in which linguistic categories are defined as complex, multilayered patterns (grammatical constructions). The patterns include not only information about the formal properties of a given liguistic unit but naturally allow the intgration of idiosyncratic details addressing the socio-pragmatic grounding of linguistic structure and systematic reference to its contextual motivations.
