تعليل سبب رسم الألف اللينة في: جرى

The content explains a rule in Arabic grammar regarding the conjugation of verbs ending with a ya’ or a waw in the present tense. When a verb originally ends with a ya’ and is conjugated to the past tense, it is written with an isolated alif. However, if the verb ends with a waw, it is written with an extended alif when conjugated to the past tense. This rule applies to ensure proper spelling and pronunciation when changing verbs from present to past tense in Arabic.
