Morphosyntax of two Turkish subject pronominal paradigms

Turkish exhibits two different sets of subject ‘agreement markers’ which show different morphosyntactic behavior from each other. It is argued here that one set of these markers are morphological suffixes while the other set are enclitics. This synchronic analysis is supported by diachronic facts which indicate that the agreement markers analyzed as suffixes have been suffixes throughout the reconstructible history of Turkic, while the agreement markers analyzed as clitics are more recent developments from reduced pronouns. A formal analysis of how these two sets of agreement markers are employed on Turkish verbs is developed within Head-driven Phrase Structure Grammar (HPSG).
