  In this paper, we show that the multiple-stem approach to nouns with a broken
plural pattern allows for greater generalizations to be stated in the
morphological system. Such an approach dispenses with truncating/deleting rules
and other complex rules that are required to account for the highly allomorphic
broken plural system. The generation of inflected sound nouns necessitates a
pre-specification of the affixes denoting the sound plural masculine and the
sound plural feminine, namely uwna and aAt, in the lexicon. The first
subsection of section one provides an evaluation of some of the previous
analyses of the Arabic broken plural. We provide both linguistic and
statistical evidence against deriving broken plurals from the singular or the
root. In subsection two, we propose a multiple stem approach to the Arabic Noun
Plural System within the Lexeme-based Morphology framework. In section two, we
look at the noun inflection of Arabic. Section three provides an implementation
of the Arabic Noun system in MORPHE. In this context, we show how the
generalizations discussed in the linguistic analysis section are captured in
Morphe using the equivalencing nodes.
