I'rab is the system of word endings that signals a word's role in a sentence. It's the part of grammar that most changes how you understand the Quran.
Key Takeaways
- I'rab is the system of word-ending changes signalling grammatical role.
- The endings (often -u, -a, -i) mark subject, object and possession.
- Arabic word order is flexible, so endings carry the meaning word order does in English.
- Verb moods are also signalled by i'rab.
- Understanding i'rab is key to parsing Quranic sentences accurately.
In English, word order tells you who did what: 'the boy hit the ball' means something different from 'the ball hit the boy'. Arabic uses i'rab — word endings — to carry that information, which is why understanding it changes everything about reading the Quran accurately.
The core idea
- Nominative (often -u): typically the subject.
- Accusative (often -a): typically the object.
- Genitive (often -i): possession and after prepositions.
Master even the basics and Quranic sentences that once blurred together start to resolve into clear subjects, objects and relationships — a major leap in understanding.
