This poster paper describes a full scale two-level morphological description (Karttunen, 1983, Koskenniemi, 1983) of Turkish word structures. The description has been implemented using the PCKIMMO environment (Antworth, 1990) and is based on a root word lexicon of about 23,000 roots words. Almost all the special cases of and exceptions to phonological and morphological rules have been implemented. Turkish is an agglutinative language with word structures formed by productive affixations of derivational and inflectional suffixes to root words. .
