Iḍāfa builds precise noun relationships
Arabic links nouns directly to express ownership, type, part–whole relationships, institutions and many fixed names.
Choose your route
Secure the two-noun architecture before building chains and adjective scope.
Core
- Build a two-noun iḍāfa.
- Remove الـ and tanwīn from the first noun.
- Place the second noun in the genitive.
Develop
- Control definite and indefinite iḍāfa.
- Change the first noun’s case with sentence role.
- Build three-noun chains.
Stretch
- Use dual and sound masculine plural construct forms.
- Resolve adjective scope accurately.
- Edit complex chains with names and suffixes.

🔎 Iḍāfa Starter
0/61. Which phrase means “the school door”?
2. What is always true of the second noun in an iḍāfa?
3. Can the first noun take tanwīn?
4. Which phrase is indefinite?
5. Choose “Layla’s book”.
6. Which noun controls the definiteness of the whole chain?
The two-part architecture
The first noun is the possessed or related item; the second noun identifies the possessor or relationship.
| Part | Arabic term | Core rule | Example |
|---|---|---|---|
| First noun | الْمُضَافُ | no الـ; no tanwīn; case comes from sentence role | بَابُ |
| Second noun | الْمُضَافُ إِلَيْهِ | always genitive; may be definite or indefinite | الْمَدْرَسَةِ |
✅ Mini-check: definiteness
0/41. Choose “a student’s book”.
2. Choose “the student’s book”.
3. Choose “our school’s library”.
4. Which statement is accurate?
The first noun changes case; the possessor stays genitive
Treat the iḍāfa as one unit inside the wider sentence.
| Sentence role | Model | Case pattern |
|---|---|---|
| Topic/subject | بَابُ الْمَدْرَسَةِ مَفْتُوحٌ. | first nominative + second genitive |
| Direct object | فَتَحْتُ بَابَ الْمَدْرَسَةِ. | first accusative + second genitive |
| After a preposition/locator | وَقَفْتُ عِنْدَ بَابِ الْمَدْرَسَةِ. | first genitive + second genitive |
The genitive of the second noun belongs to the iḍāfa relationship. The case of the first noun belongs to the sentence around it.
✅ Mini-check: case across the chain
0/41. Choose the subject form “The school door is open.”
2. Choose “I opened the school door.”
3. Choose “I stood by the school door.”
4. What controls the case of the first noun?
Longer iḍāfa chains
Every term except the final possessor remains bare; the final term controls definiteness.
Dual and sound masculine plural in iḍāfa
The same nūn-deletion rule used with attached possessive suffixes applies before a noun possessor.
| Independent form | Construct form | Example |
|---|---|---|
| طَالِبَانِ | طَالِبَا | طَالِبَا الْمَدْرَسَةِ |
| طَالِبَيْنِ | طَالِبَيِ | قَابَلْتُ طَالِبَيِ الْمَدْرَسَةِ |
| مُعَلِّمُونَ | مُعَلِّمُو | مُعَلِّمُو الْمَدْرَسَةِ |
| مُعَلِّمِينَ | مُعَلِّمِي | تَحَدَّثْتُ مَعَ مُعَلِّمِي الْمَدْرَسَةِ |
Sound feminine plurals do not have a final nūn to delete: طَالِبَاتُ الْمَدْرَسَةِ remains structurally intact.
✅ Mini-check: construct number forms
0/41. Choose “the school’s two students” as a nominative phrase.
2. Choose “I met the school’s two students.”
3. Choose “the school’s teachers” as a nominative phrase.
4. Choose “I spoke with the school’s teachers.”
Adjective scope: which noun is described?
The adjective normally follows the complete iḍāfa, so agreement evidence must identify its target.
| Meaning | Arabic | Agreement evidence |
|---|---|---|
| the school’s large door | بَابُ الْمَدْرَسَةِ الْكَبِيرُ | masculine nominative adjective describes بَابُ |
| the door of the large school | بَابُ الْمَدْرَسَةِ الْكَبِيرَةِ | feminine genitive adjective describes الْمَدْرَسَةِ |
| the school door is large | بَابُ الْمَدْرَسَةِ كَبِيرٌ | indefinite nominative predicate |
✅ Mini-check: adjective scope
0/41. Choose “the school’s large door”.
2. Choose “the door of the large school”.
3. Choose “the school door is large”.
4. What helps identify adjective scope?
Names, suffixes and established expressions
The final possessor can take several forms.
| Final possessor type | Example | Meaning |
|---|---|---|
| Definite common noun | كِتَابُ الطَّالِبِ | the student’s book |
| Indefinite common noun | كِتَابُ طَالِبٍ | a student’s book |
| Proper name | كِتَابُ لَيْلَى | Layla’s book |
| Possessive suffix | كِتَابُ صَدِيقِي | my friend’s book |
| Longer chain | كِتَابُ صَدِيقِ أَخِي | my brother’s friend’s book |

| Draft | Improved version | Reason |
|---|---|---|
| الْبَابُ الْمَدْرَسَةِ | بَابُ الْمَدْرَسَةِ | The first noun cannot take الـ. |
| بَابٌ الْمَدْرَسَةِ | بَابُ الْمَدْرَسَةِ | The first noun cannot take tanwīn. |
| بَابُ الْمَدْرَسَةُ | بَابُ الْمَدْرَسَةِ | The possessor is genitive. |
| بَابُ مَدْرَسَةٍ الْكَبِيرُ | بَابُ مَدْرَسَةٍ كَبِيرٌ / بَابُ الْمَدْرَسَةِ الْكَبِيرُ | Definiteness and intended meaning must be made clear. |
| طَالِبَانِ الْمَدْرَسَةِ | طَالِبَا الْمَدْرَسَةِ | Dual construct drops nūn. |
| مُعَلِّمُونَ الْمَدْرَسَةِ | مُعَلِّمُو الْمَدْرَسَةِ | Sound masculine plural construct drops nūn. |
| بَابُ الْمَدْرَسَةِ الْكَبِيرَةُ | بَابُ الْمَدْرَسَةِ الْكَبِيرَةِ | An adjective describing the genitive school is also genitive. |
