Lesson 92 – الدَّرْسُ الثَّانِي وَالتِّسْعُونَ

Patterns of abstract verbs - أَوْزانُ الأفْعالِ المُجَرَّدَةِ

The abstract treble verbالفِعْلُ الثُلاثيُّ المُجَرَّدُ

  • The treble verb is that which contains three letters of its root, while the abstract is that which does not contain any morphological augmentation.
  • To study the patterns of the abstract treble verb, we have to study its regular form, i.e.: the sound verb الفِعْلُ الصَّحِيحُ and the irregular forms, i.e. in the cases of existence of weak letters حُرُوفُ الْعِلَّةِ (either in the beginning “model verb الْفِعْلُ الْمِثَالُ, in the middle “hollow verb الْفِعْلُ الأَجْوَفُ, or in the end “deficient verb الفعل الناقص”) or the case of double consonant الْفِعْلُ الْمُضَعَّفُ.
  • N.B.: All the patterns of the abstract treble verbs are formed according to what’s found in Arabic dictionaries, so it has be memorized as they are incommensurable, i.e. there is NO rule to apply on any three letters root verb to know its proper pattern. The only procedure that we can make is to ask our teacher or look up the verb in the dictionary.
  • The above mentioned note is applicable only on the abstract treble verb, i.e. the augmented treble verbs and the quadruple verbs (either abstract or augmented) are regular and commensurable.
  • In the following parts we will learn the different patterns in all cases.
