    <Paragraph position="0"> Computational models of sentence syntax are increasingly based on well-defined linguistic theories and implemented using general formalisms; by contrast, morphology and phonology in the lexicon tend to be handled with tailor-made hybrid formalisms selected for properties such as finite state compilability, object orientation, default inheritance, or procedural efficiency. The linguistically motivated Prosodic Inheritance (PI) model with defaults captures morphotactic and morphophonological generalisations in a unified declarative formalism, and has broad linguistic coverage of both concatenative morphology and the notorious 'hard cases' of non-concatenative morphology. This paper integrates the PI concepts underlying previous descriptions of German Umlaut (Reinhard 1990a, 1990b), Bantu tone morphology and Arabic C-V intercalation (Gibbon 1990); Umlaut and intercalation are treated here. PI descriptions are currently Implemented in a DATR dialect (Gibbon 1989; for DATR cf. Evans &amp; Gazdar 1989, 1990, 1989a, 1989b); DATR was chosen for its syntactic simplicity and its explicit formal semantics.</Paragraph>
