In relatively free word order languages, grammatical functions are intricately related to case marking. 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 predicateargument structure. This is achieved by treating case markers as type shifters. Unlike other CG formulations, type shifting does not proliferate or cause spurious ambiguity. Categories of all argument-encoding grammatical functions follow 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.

. In this paper we outline a lexical organization for Turkish that makes use of lexical rules for inflections, derivations, and lexical category changes to control the proliferation of lexical entries. Lexical rules handle changes in grammatical roles, enforce type constraints, and control the mapping of subcategorization frames in valency-changing operations. A lexical inheritance hierarchy facilitates the enforcement of type constraints. The resulting grammar architecture has morphology embedded in the lexicon. The design has been tested as part of an HPSG grammar for Turkish. Rebracketing in compounds and phrasal scope in affixation present formidable difficulties for lexical rules. In terms of performance, run-time execution of the rules seems to be a far better alternative than pre-compilation. The latter causes exponential growth in the lexicon due to intensive use of inflections and derivations in Turkish. 1. Introduction We report on an experiment to model agglutinating morph...
