Lesson 32الدَّرْسُ الثَّانِي وَالثَّلاثُونَ الفِعْلُ الصَّحِيحُ والمُعْتَلُّ

Types of Defective Verbs - أَنْوَاعُ الْفِعْلِ الْمُعْتَلِّ

  • The type of a defective verb is determined according to the place of the defective letter in it (beginning, middle and last), such as وَعَدَ, قَالَ and سَعَى. This lesson elaborates the types of defective verbs.
    1. A defective verb with one defective letter:

وَعَدَ

A past-form verb beginning with a defective letter. It is always in the past form, because the present form verb may begin with the letter yaa’, such as /Yaktubu/, i.e. to write. The yaa’ letter here is not a defective letter, but it just indicates the present form of the verb.

Note: a past-form verb never begins with the long vowel (a)
