جموع لا مفرد لها من لفظها

الملخص EN

The purpose of this research was to survey the plurals that the Arabs did not articulate their singulars or use in their speech, and so the plural appears without its singular, or it came in such a way that differs when used as singular.

The purpose is to gather and arrange these cases alphabetically in order fo form the core of linguistic dictionary of plurals.

The research showed that there were some reasons for the differences between the plural and its singular and that Arabs‘ abstaining from using the singular forms of these plurals was not due to incapability or incompetence, but because they got along with something else in their language and what existed in large amounts in their speech.

The research also showed that many of these plurals were controversial and Arab scholars assumed, in many cases, some singulars even if they were not used.
