Numeral phrases in Standard Arabic are known for gender and number mismatches1 between the numeral and the enumerated noun. This article reduces these mismatches to two morphological deletion rules. The first deletes the feminine morpheme of the numeral when the enumerated noun is feminine, and the second deletes the plural morpheme of the enumerated noun when the numeral carries a plural morpheme. The first rule is further restricted to deleting only feminine morphemes that are underlyingly part of the numeral, and not inherited via agreement with a feminine enumerated noun via a syntactic agreement process. The analysis in this article is consistent with Sadiqi's (2006) claim that the feminine form in Arabic is the basic one from which the masculine was derived historically by reducing the feminine form. The deletion analysis here also finds support from Chomsky's approach of deriving the masculine from the feminine as theoretically less costly and more explanatorily adequate.
