The Arabic number system
Arabic distinguishes exactly one, exactly two, and three or more. The dual is not optional when the meaning is exactly two in careful standard Arabic.
| Number | Masculine example | Feminine example | Meaning |
|---|---|---|---|
| Singular | طَالِبٌ | طَالِبَةٌ | one student |
| Dual nominative | طَالِبَانِ | طَالِبَتَانِ | two students |
| Dual acc./gen. | طَالِبَيْنِ | طَالِبَتَيْنِ | two students after case trigger |
| Plural | طُلَّابٌ | طَالِبَاتٌ | three or more |
Practical IGCSE rule: Use ـانِ for a dual subject in the nominative; use ـيْنِ after a preposition and in object/genitive positions.

Building and using the dual
Masculine / unmarked noun
كِتَابٌ ← كِتَابَانِ / كِتَابَيْنِ
مُعَلِّمٌ ← مُعَلِّمَانِ / مُعَلِّمَيْنِ
Noun ending in ة
مَدْرَسَةٌ ← مَدْرَسَتَانِ / مَدْرَسَتَيْنِ
طَالِبَةٌ ← طَالِبَتَانِ / طَالِبَتَيْنِ
Do not use a numeral plus plural for two. Prefer كِتَابَانِ, not *اِثْنَانِ كُتُبٌ in an ordinary noun phrase.
