The Division of The Verb Into Declinable and Indeclinable 1
What do you understand about a declinable verb?
What verbs are declinable?
What kinds of cases does a verb have?
What is the nominative sign of verb?
What is the subjunctive sign of a verb?
What is the jussive sign of a verb?
The cases of a verb are determined by the changing of the end of the verb due to its placement in a sentence.
The only verb that is declinable is the aorist tense. For example: یَقرَﺃ یَکتُبُ (he is writing, he is reading)
There are three cases for declinable verbs: the nominative case, the subjunctive case and the jussive case.
The principle of the nominative case is the verb having a dummah.
The nūn takes the place of the dummah in the aorist verbs, which are every verb in the aorist tense that is connected to:
• the dual alif: یَفعَلانِ تَفعَلانِ
• the plural wāw: یَفعَلُونَ تَفعَلُونَ
• the you feminine pronoun (yā'): تَفعَلینَ
The principle of the subjunctive case is the verb having a fathah.
The subtraction of the nūn takes the place of the fathah in the aorist verbs. For example: ﺃن یَفعَلاThe sign of the jussive case in a verb is the sakūn.
The subtraction of the nūn takes the place of the sakūn in the aorist verbs. For example: لَم یَفعَلا
The subtraction of the weak letter when it is the last root letter of a weak verb takes the place of a sakūn. For example: لَم یَرمِ (he did not throw)
