We present a notation for the declarative statement of morphological relationships and lexieal rules, based on the traditional notion of Word and Paradigm (cf Hockett 1954). The phenomenon of blocking arises from a generalized version of Kiparsky's (1973) Elsewhere Condition, stated in terms of ordering by subsumption over paradigms. Orthographic constraints on morphemic alternation are described by means of string equations (Siekmann 1975). We indicate some criticisms to be made of our approach from both linguistic and computational perspectives and relate our approach to others such as Finite-State Morphology (Koskenniemi 1983), DATR (Gazdar and Evans 1989) and object-oriented morphophonemics.
