In this thesis, our goal is to generate Turkish surface forms from Predicate-Argument Structure (PAS) using a morpheme-based lexicon. The system uses a model which integrates inflectional morphology and syntax in which the building blocks are morphemes. The algorithm is based on bottom-up use of the category-semantics pairing coming from the lexicon. The generator presented in this thesis is capable of partial phrase formation. We discuss design and implementation aspects of the generator.
