</SectionTitle>
    <Paragraph position="0"> This paper presents a language to express morphological processes and shows how that language applies straightforwardly to Arabic morphology 2. This approach to morphology is directly compatible with unification-based frameworks in that lexical entries are feature structures, and morphological processes are related to unification of feature structures.</Paragraph>
    <Paragraph position="1"> This work departs from two-level morphology, which has been at the center of computational morphology since the implementation of URKIMMO (Koskenniemi 1983) and was applied to Arabic morphology first by Kay (1987), then by Beesley (1989, 1996), Kiraz (1994, 1996a) and to Syriac morphology by Kiraz (1996b). Two-level morphology is characterized by an emphasis on phonological (or orthographic) rules, and has a rudimentary treatment of morphology itself.</Paragraph>
    <Paragraph position="2"> The language presented in this paper proposes a declarative approach to morphology 3  per; but the approach can be extended to derivational morphology.</Paragraph>
    <Paragraph position="3"> in which morphological processes are represented as paradigms of relations between feature structures and orthographic/phonological forms. This approach is inspired from work done by Calder (1989) who uses paradigms to organize morphological information, and string equations to handle string operations.</Paragraph>
