Case Endings (I'rab) · الإعراب

The vowel endings that show grammatical function

2 Quran examples
The rule

Arabic nouns change their endings based on grammatical function. This is called الإعراب (iʿrāb).

Three Cases:

1. **Nominative (مرفوع - Marfūʿ):** ـُ (damma) - for subjects

2. **Accusative (منصوب - Manṣūb):** ـَ (fatha) - for objects

3. **Genitive (مجرور - Majrūr):** ـِ (kasra) - after prepositions

With Tanwin (indefinite):

  • Nominative: ـٌ (-un)
  • Accusative: ـً (-an)
  • Genitive: ـٍ (-in)
  • In the Quran· tap the reference to open the verse

    إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ

    2:173

    Inna Allāha ghafūrun raḥīm

    Indeed, Allah is Forgiving, Merciful

    بِسْمِ ٱللَّهِ

    1:1

    Bismi Allāh

    In the name of Allah

    Tips to remember

    • 1ٱللَّهَ (accusative) after إنَّ vs ٱللَّهِ (genitive) after بِ
    • 2غَفُورٌ has tanwin because it is indefinite and nominative
