In relatively free word order languages, grammat- ical functions are intricately related to case mark- ing. Assuming an ordered representation of the predicate-argument structure, this work proposes a Combinatory Categorial Grammar formulation of relating surface case cues to categories and types for correctly placing the arguments in the predicate- argument structure. This is achieved by treat- ing case markers as type shifters. Unlike other CG formulations, type shifting does not prolifer- ate or cause spurious ambiguity. Categories of all argument-encoding grammatical functions fol- low from the same principle of category assignment. Normal order evaluation of the combinatory form reveals the predicate-argument structure. The appli- cation of the method to Turkish is shown.
