Mastering the Signs of I’rab: A Complete Guide for Beginners.

The Ultimate Guide to the Signs of I’rab (علامات الإعراب)

If you are learning Arabic grammar (Nahw), understanding I’rab (الإعراب) is non-negotiable. I’rab is the system that determines the ending of a word based on its position in a sentence. In this post, we simplify the Signs of I'rab so you can read and speak Arabic with precision.


1. The Primary Signs (العلامات الأصلية)

Primary signs are the default "Harakat" (vowels). These apply to singular nouns, broken plurals, and the present tense verb (not connected to anything).

State (الحالة) Sign (العلامة) Arabic Term
Nominative Damma (ـُ) الرفع
Accusative Fatha (ـَ) النصب
Genitive Kasra (ـِ) الجر
Jussive Sukun (ـْ) الجزم

2. The Secondary Signs (العلامات الفرعية)

Sometimes, Arabic uses letters instead of vowels to show I’rab. This occurs in specific noun and verb categories:

  • The Dual (المثنى): Uses Alif (ـان) for Raf' and Ya (ـين) for Nasb/Jarr.
  • Sound Masculine Plural (جمع المذكر السالم): Uses Waw (ـون) for Raf' and Ya (ـين) for Nasb/Jarr.
  • The Five Nouns (الأسماء الخمسة): These follow the sequence of Waw, Alif, Ya (أبو، أبا، أبي).
