5 Conclusion
</SectionTitle>
    <Paragraph position="0"> This paper has described a computational, declarative approach to prosodic morphology which uses inviolable constraints formulated in a sufficiently expressive formalism (here: MicroCUF) together with a restrictive incremental optimization component.</Paragraph>
    <Paragraph position="1"> The approach has been illustrated by implementing an a-templatic analysis of a fragment of Modern Hebrew verbs. The full grammar behind the illustrative fragment covers additional detail such as antigemination effects (noded-im, *nod d-im 'they (masc.) wander'), spirantization, B7 sibilant metathesis, etc.</Paragraph>
    <Paragraph position="2"> Also, the formalization of X/~ presented here is actually a special case of the more powerful notion of resequencing, whose application to Tigrinya vowel coalescence and metathesis was demonstrated in Walther (1997).</Paragraph>
    <Paragraph position="3"> Despite the initial emphasis on incremental optimization, a compilation technique was later proposed to remove the need for run-time optimization and guarantee fully bidirectional processing of prosodic morphology. Although the general idea of using a finite-state oracle to guide a parser has been previously proposed for context-free grammars (Johnson 1996), both the details of our implementation of the idea and its specific application to prosodic morphology are believed to be novel. It was emphasized how the proposed technique aided in a simple treatment of unknown words. Note that unknown words are not normally integrated into finite-state transducer models of prosodic morphology, although the necessary extensions appear to be possible (K. Beesley, p.c.). Finally, the fact that a hybrid setup rather than a pure finite-state approach was chosen has been motivated inter alia by reference to additional phenomena such as antigemination and reduplication that require the richer notion of token identity. Future research will especially focus on detailed analyses of reduplication phenomena to secure the relevance of the present approach to prosodic morphology at large.</Paragraph>
