Possession: the iḍāfa construction
Arabic · Key Stage 2 · The School
Two nouns, no 'of'
بابُ البَيْتِ — the door of the house. كِتابُ الوَلَدِ — the boy's book. This construction is called IDAFA, meaning 'addition'. Two nouns are simply placed side by side, and Arabic reads the connection without any extra word.
Only the second noun gets 'the'
In بابُ البَيْتِ, only البَيْت carries the article ال. The first noun, باب, never takes ال in an iḍāfa, even though the whole phrase means "THE door of THE house". It becomes definite because it sits next to a definite noun. It does not need the article itself.
Ownership without a possessive word
English has three ways to show possession: 'of', an apostrophe-s, or a possessive word. Arabic's iḍāfa does the job of the first two with one simple rule. Noun, then noun. The first one loses its article. No extra word is needed anywhere.
Reading it in the right order
غُرْفةُ الطّالِبِ reads word for word as 'room-of the-student', but the natural English is 'the student's room'. Try it with مَدْرَسةُ البِنْتِ — literally 'school-of the-girl' — and flip it into natural English: 'the girl's school'. Say each phrase aloud before you flip it, so the sound and the meaning both stick. Practise flipping three more of your own before checking with a partner.
