Co mputational models of morphology and phonology have traditiona- lly assu med as a starting point a morphotactic model where morpehe mes are drawn fro m sublexicons and concatenated left-to-right. In defining the lexicon-morphotactic level of a syste m, this 'continuation-class' model has been the de facto standard im- ple mentation in various software toolkits. Fro m surveying of a nu mber of typologi- cally different languages, we propose a more co mprehensive feature-driven model of morphotactics that provides the linguist with various operations that are designed to concisely define a variety of local and global co-occurrence restrictions. We also sketch ways to imple ment these operators in finite-state-transducer-based models of morphology.
