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.
