Similarity: a defect to prevent exchange

Abstract

Similarity is one of the topics that have received great attention from grammarians for its involvement with many grammatical and linguistic sections, including the subject of this research, which revolves around the subject of similarity in the section of the forbidden to inflect, as the noun may be prevented from inflection if it resembles another noun and balances it in one of its forms. This research came in two chapters: the first of them dealt with the similarity affecting the prevention of inflection, which prevents the noun from inflection to a semi-verb; this comes in multiple forms, including what prevents the inflection of indefinite and definite nouns, and what prevents only definite nouns, and inflect indefinite nouns. The second dealt with the ineffective similarity, in which the noun does not refrain from being inflected despite the existence of the similarity pretext.

The research produced a number of results, including:

• Not every similarity between a noun and a verb prevents inflection.
• The noun similar to the verb may be transformed from a verb, such as: (Yashkur), and it may be transformed from an adjective, such as: (Ahmar), and it may be untransformed from them, such as: (Arba').
• Some of the nouns are forbidden to be inflected as indefinite and definite, which are those that are formed as adjectives, such as: (Ahmar) and (Aswad); and some are refrained from inflection as definite and inflected as indefinite, which are those with nomination as one of their two pretexts.
• What is not prevented from inflection is what comes in a common form between the noun and the verb, which is more in nouns.
