Arabic has an entirely separate grammatical number, the dual, reserved for exactly two of something, with its own ending. Body parts that come in pairs — eyes, hands — are almost always dual, and this is the last new noun-pattern you need before this course starts building verbs.

BY THE END OF THIS CHAPTER YOU WILL BE ABLE TO
Form the dual of a noun with ‑āni (nominative) or ‑ayni (accusative/genitive)
Describe dual nouns with correctly-agreeing plural adjectives
Count exactly two of something without using the number ‘two’
Read a verse that uses the dual for a pair of body parts
TEACHER NOTES
Pacing: 55–70 min — genuinely one of the harder chapters.
Prerequisite check: Everything through Chapter Twenty. This chapter is now later than the original course intended, so students have more foundation than before.
Watch out for: Several earlier chapters (10, 13, 18) planted recognise-only dual forms — have students find and re-read those passages now that the grammar is explicit.
01 — LISTEN & REPEAT
حِوَارٌDialogue
Yūsuf and Maryam talk about pairs of things they have. Listen twice, then read aloud.
Notice the dual ending changes depending on the sentence's case — ـَانِ for nominative, ـَيْنِ for accusative/genitive.

03 — HOW THE LANGUAGE WORKS
رُكْنُ الْقَوَاعِدِGrammar Corner
The dual has its own ending. To make any noun dual, drop tanwīn and add ـَانِ (nominative) or ـَيْنِ (accusative/genitive).
كِتَابٌ → كِتَابَانِ
kitāb → kitābāni a book → two books (subject)
عِنْدِي كِتَابَيْنِ
‘indī kitābayni I have two books (after عِنْدِي, the noun takes the accusative/genitive dual)
Adjectives describing dual nouns are also dual: سُورَتَانِ قَصِيرَتَانِ (“two short sūrahs”) — the same agreement rule from Chapter Five, now extended one more step.
Quick check: what is the dual of عَيْنٌ (an eye) in the nominative? (عَيْنَانِ.)
04 — READING THE SOURCE
وَقْفَةٌ قُرْآنِيَّةٌQur'ān Connection
A short, memorable verse listing pairs of human features — every one of them in the dual.
Have We not made for him two eyes? And a tongue and two lips?
أَلَمْ نَجْعَل
alam naj‘al
have We not made
لَّهُ عَيْنَيْنِ
lahu ‘aynayni
for him two eyes
وَلِسَانًا وَشَفَتَيْنِ
wa lisānan wa shafatayni
and a tongue and two lips
عَيْنَيْنِ and شَفَتَيْنِ are both dual, accusative. نَجْعَل is a verb form you'll formally meet soon — for now, just notice how naturally the dual nouns you learned this chapter sit inside real Qur'ānic text.

SKILLS PRACTICE
التَّحَدُّثُSpeaking
Pair work
Partner drill. Name two things you have exactly two of — عَيْنَانِ، يَدَانِ، أَخَوَانِ — and describe them with a dual adjective.
Recycling round. If the earlier "recognise-only" dual forms from Chapters Ten, Thirteen, and Eighteen came up naturally, this is the moment to circle back and have students produce them for the first time.

Tip
ـَانِ vs ـَيْنِ
كِتَابَانِ
كِتَابَيْنِ
The nominative ending sounds like ‑āni; the accusative/genitive like ‑ayni — listen for the diphthong.
1. False — he has two brothers, not sisters. 2. True. 3. True.
