This document discusses the possessive construction in Arabic grammar. It explains that the possessive phrase "افضم and هيلا افضم" combines two nouns, with the first noun being possessed by the second. The possessed noun is called "افضمل" and the possessing noun is called "هيلا افضمل". Examples of the possessive construction are given, such as "كتاب المعلم" meaning "the teacher's book". The document provides rules for the possessive construction, such as the possessed noun never taking the definite article "ال" and the possessing noun taking a kasrah on the last letter.
