Compound Numbers Twenty-One through Ninety-Nine | Arabic (Levantine) Grammar

Lebanese builds 21–99 in the order unit + و + decade: سبعة وأربعين is literally “seven and forty,” not “forty-seven.” The order is the mirror image of English, but the more important grammar comes after it: a noun counted by the complete number is singular, while the units “one” and “two” can still preserve gender agreement.

The forms below are informal, urban Lebanese with Beirut pronunciation. Formal Arabic has case-marked alternatives such as واحد وعشرون; those belong to formal reading, not ordinary Lebanese conversation.

Build from the right-hand digit first

Start with the unit, join و to the following decade in Arabic spelling, and say the decade last.

Number	Lebanese form	Internal order
21	واحد وعشرين wāḥad w-ʿishrīn	one + and + twenty
34	أربعة وتلاتين arbaʿa w-tlētīn	four + and + thirty
47	سبعة وأربعين sabʿa w-arbaʿīn	seven + and + forty
58	تمانية وخمسين tmēnye w-khamsīn	eight + and + fifty
99	تسعة وتسعين tisʿa w-tisʿīn	nine + and + ninety

عندي سبعة وأربعين رسالة ما قريتن بعد.

ʿinde sabʿa w-arbaʿīn risēle ma ʾrēton baʿd.

I have forty-seven messages I haven't read yet. (informal; unit before decade, singular counted noun)

رقم الطلب تسعة وتسعين، مش تسعة وستين.

raʾam eṭ-ṭalab tisʿa w-tisʿīn, mish tisʿa w-sittīn.

The order number is ninety-nine, not sixty-nine. (informal; contrast where the decade carries the difference)

English listeners often latch onto the first word and mentally hear “forty…” as soon as a number begins. Lebanese makes you wait for the decade. In phone calls or noisy shops, repeat the whole number rather than correcting only its last word.

💡

For a two-digit number, glance at the ones digit first. Say that unit, attach و to the decade, then say the tens: 47 → 7 + و + 40.

One and two preserve a gender choice

For a careful production baseline, use masculine واحد and اتنين with a masculine counted noun, but feminine وحدة and تنتين with a feminine counted noun. The noun itself stays singular because 21 and 22 are complete numbers above ten.

Number	Masculine counted noun	Feminine counted noun
21	واحد وعشرين كتاب wāḥad w-ʿishrīn ktēb	وحدة وعشرين سيارة waḥde w-ʿishrīn sayyāra
22	اتنين وعشرين كتاب tnēn w-ʿishrīn ktēb	تنتين وعشرين سيارة tintēn w-ʿishrīn sayyāra
31	واحد وتلاتين طالب wāḥad w-tlētīn ṭāleb	وحدة وتلاتين طالبة waḥde w-tlētīn ṭālbe
42	اتنين وأربعين ملف tnēn w-arbaʿīn malaff	تنتين وأربعين صفحة tintēn w-arbaʿīn ṣafḥa

طلبوا واحد وعشرين كتاب للمكتبة.

ṭalabo wāḥad w-ʿishrīn ktēb lal-maktabe.

They ordered twenty-one books for the library. (informal; masculine واحد and singular كتاب)

وصلت وحدة وعشرين سيارة عالكراج.

wiṣlet waḥde w-ʿishrīn sayyāra ʿal-karāzh.

Twenty-one cars arrived at the garage. (informal; feminine وحدة and singular سيارة)

بقي تنتين وعشرين دقيقة عالموعد.

biʾe tintēn w-ʿishrīn dʾīʾa ʿal-mawʿed.

There are twenty-two minutes left until the appointment. (informal; feminine two with دقيقة)

Real Lebanese speech also shows leveling, especially when speakers read a bare figure or price: وحدة وعشرين may occur without regard to the gender of a later noun (informal; variable). Learn gender agreement for deliberate production, but recognize that this part of the colloquial system is less rigid than formal paradigms suggest.

Three through nine use the independent unit form

In an urban Lebanese compound, the unit is followed by the decade, not directly by the counted noun. It therefore appears in its independent form: تلاتة، أربعة، خمسة.... In widespread Lebanese usage, these forms are commonly leveled across the gender of the eventual noun.

عنا تلاتة وعشرين طالب وتلاتة وعشرين طالبة.

ʿinna tlēte w-ʿishrīn ṭāleb w-tlēte w-ʿishrīn ṭālbe.

We have twenty-three male students and twenty-three female students. (informal Lebanese; same independent unit, singular nouns)

حجزنا خمسة وتلاتين غرفة للمؤتمر.

ḥazhazna khamse w-tlētīn ghorfe lal-muʾtamar.

We booked thirty-five rooms for the conference. (informal; independent خمسة and singular غرفة)

This differs from خمس غرف “five rooms,” where the number is directly before a plural noun and takes a construct counting form. The intervening decade changes the structure: خمسة وتلاتين غرفة. See numbers three through ten for that smaller-number pattern.

💡

Do not copy the 3–10 phrase into a compound. خمس غرف has construct خمس plus a plural; خمسة وتلاتين غرفة has independent خمسة, a decade, and a singular.

The counted noun is singular

From 11 upward, a directly counted Lebanese noun is normally singular: سبعة وعشرين يوم، أربعة وخمسين صفحة، تسعة وتسعين شخص. English keeps a plural after every number above one, so this is a persistent transfer error.

الدورة مدتها أربعة وخمسين يوم.

ed-dawra muddeta arbaʿa w-khamsīn yōm.

The course lasts fifty-four days. (informal; singular يوم after the compound)

الملف فيه تمانية وستين صفحة.

el-malaff fī tmēnye w-sittīn ṣafḥa.

The file has sixty-eight pages. (informal; singular صفحة)

Plural meaning is carried by the numeral phrase; the noun does not need to repeat it. This does not make the noun semantically singular—it is the grammatical form licensed after the number.

Reading prices and exact figures aloud

Prices use the same syntax. The currency noun remains singular, and the whole figure normally precedes it.

سعر التذكرة خمسة وعشرين دولار.

siʿer et-tazkara khamse w-ʿishrīn dōlār.

The ticket costs twenty-five dollars. (informal; price read aloud)

الحساب طلع اتنين وسبعين دولار بالضبط.

el-ḥsēb ṭileʿ tnēn w-sabʿīn dōlār biḍ-ḍabṭ.

The bill came to exactly seventy-two dollars. (informal; common standalone اتنين in a price reading)

The last example shows common masculine/default اتنين when no noun gender contrast is being foregrounded. The table's اتنين/تنتين agreement remains a useful controlled production pattern; natural speech permits leveling toward the default form.

Exact versus approximate quantity: a dialogue

قديش بدكن كرسي للقاعة، شي تلاتين؟

ʾaddēsh bidkon kerse lal-ʾāʿa, shi tlētīn?

Maya: How many chairs do you need for the hall—about thirty? (informal; approximate quantity with شي)

اتأكدت من اللائحة: بدنا سبعة وعشرين كرسي بالضبط.

itʾakkadet min el-lēyḥa: bidna sabʿa w-ʿishrīn kerse biḍ-ḍabṭ.

Rami: I checked the list: we need exactly twenty-seven chairs. (informal; exact compound and singular noun)

شي تلاتين and حوالي تلاتين are genuinely approximate; بالضبط makes the exact reading explicit. The approximation page covers ranges and looser estimates.

Common Mistakes

Copying English decade-first order

❌ أربعين وسبعة كتاب.

Incorrect for forty-seven—Lebanese says the unit before the decade.

✅ سبعة وأربعين كتاب.

sabʿa w-arbaʿīn ktēb.

Forty-seven books. (informal; unit + و + decade)

Keeping the English plural noun

❌ عندي خمسة وتلاتين كتب.

Incorrect—after a compound above ten, the counted noun is singular.

✅ عندي خمسة وتلاتين كتاب.

ʿinde khamse w-tlētīn ktēb.

I have thirty-five books. (informal; singular counted noun)

Importing the 3–10 construct form

❌ حجزنا خمس وتلاتين غرفة.

Incorrect in the compound baseline—خمس is the form directly before a counted noun, not before a decade.

✅ حجزنا خمسة وتلاتين غرفة.

ḥazhazna khamse w-tlētīn ghorfe.

We booked thirty-five rooms. (informal; independent unit form)

Mixing formal case forms into Lebanese speech

❌ السعر واحد وعشرون دولار.

✅ السعر واحد وعشرين دولار.

es-siʿer wāḥad w-ʿishrīn dōlār.

The price is twenty-one dollars. (informal Lebanese; invariant عشرين)

Key Takeaways

Say the unit first, attach و, then say the decade: سبعة وأربعين. Use a singular counted noun after the complete number. In a careful baseline, make 1 and 2 agree—واحد/وحدة، اتنين/تنتين—while recognizing real Lebanese leveling. Units 3–9 use their independent form before the decade, so contrast خمس غرف with خمسة وتلاتين غرفة. Keep formal case forms such as عشرون out of ordinary Beirut speech.
