عَدَد

root: ع-د-د / *noun* / plural: أَعْداد / definition: number

I remember learning the grammar for using Arabic numbers at university. It seemed fairly simple as there were essentially three sets of rules: one for the numbers 3-10, one for 11-99, and another for whole hundreds, thousands, etc.

But when I looked a little deeper, I realised that there were a few little exceptions and special cases! Well, now’s a good a time as ever to delve into the details…

Here’s a few things to know before we get into the rules:

- the
**counted noun**is the noun that’s—yes—being counted, or being specified by the number; so if we say “8 planets”,*planet*is the counted noun

- a
**compound number**is a number that’s a mix of units, tens, thousands, etc—for example: 34, 108, 7020, and 97592

- in this post, I’ll be focusing more on the grammatical relationship between the number and counted noun, and not so much on how to say each number—I think we’d need a whole other post on that!

- there’s a neat tool called
**تفقيط**that’s amazing when you need to see a number written out in words and don’t feel like consulting your grammar notes(!)—find out how to use it best here

Like I mentioned at the start, there are three main sets of rules… although, as you can see, there are subsets too:

**3-10**

**11-99**- 11-19
- whole tens

- compound numbers ending in 1 or 2
- compound numbers ending in 3-9

**100+**- whole hundreds, thousands, etc
- compound numbers

(Note: the reason we start at 3 is because for the numbers 1 and 2, the counted noun either takes the singular or dual form!)

Let’s begin!

3-10

For the numbers 3 to 10, the **number** is:

- written in words (not figures)
- the opposite gender to that of the (singular form of the) counted noun

And the **counted noun** is:

- plural
- مجرور (in genitive case, as the number and counted noun are in an إضافة)

Examples:

سَبعَةُ كُتُبٍ

*7 books*

أَربَعُ نِساءٍ

*4 women*

عَشَرُ مَرّاتٍ

*10 times*

11-99

For the numbers 11-99, we write the number in figures as opposed to words. However, I’ll write them out in the examples so that the grammar is clear.

With this category of numbers, the **counted noun** is always:

- singular
- منصوب (in accusative case)

However, the **gender of the number** in relation to the gender of the counted noun differs. Let’s look at the different sub-groups…

11-19

For 11, 12, and all of the “teen” numbers, the **number** is:

- the same gender as that of the counted noun

Examples:

اِثنَتا عَشرَةَ رِوائيّةً

*12 (female) novelists*

أَحَدَ عَشَرَ عاماً

*11 years*

ثَمانِيَةَ عَشَرَ بَيتاً

*18 houses*

سِتَّ عَشرَةَ صَفحةً

*16 pages*

Note how, for the numbers **13-19**, the two components of the number (tens and units) are opposite in gender. The gender of the *ten* determines the gender of the number.

I.e. خَمسَةَ عَشَرَ is masculine and خَمسَ عَشرَةَ is feminine.

whole tens

For the whole tens—i.e. 20, 30, 40, etc—the **number** is:

- invariable for gender

Examples:

عِشرونَ ساعةً

*20 hours*

تِسعونَ يَوماً

*90 days*

ثَلاثونَ شَخصاً

*30 people*

Remember that the tens have sound masculine plural endings that vary according to case—they either end in ـونَ (as in the examples above) or ـينَ.

compound numbers ending in 1 or 2

For compound numbers ending in 1 or 2, the **number** is:

- the same gender as that of the counted noun

Examples:

واحِدٌ وَعِشرونَ قَلَماً

*21 pens*

اِثنَتانِ وَسَبعونَ مَدينةً

*72 cities*

واحِدَةٌ وَسِتّونَ مِتراً

*61 metres*

اِثنانِ وَخَمسونَ أُسبوعاً

*52 weeks*

compound numbers ending in 3-9

For compound numbers ending in a unit from 3 to 9, the **number** is:

- the opposite gender to that of the counted noun

Examples:

ثَلاثَةٌ وَثَلاثونَ شارِعاً

*33 roads*

أَربَعٌ وَعِشرونَ ساعَةً

*24 hours*

سَبعٌ وَتِسعونَ مِنطَقَةً

*97 areas*

خَمسَةٌ وَسِتّونَ زَعيماً

*65 leaders*

100+

The numbers 100 (which can either be spelt مِئة or مائة) and above are also written in figures.

Larger and more complex numbers often combine different sets of rules. For example, *3000 shelves* is ثَلاثَةُ آلافِ رَفٍّ—where أَلف (*a thousand*) is the counted noun of ثلاثة (and therefore plural and مجرور), and رَفّ is the counted noun of 3000 (and therefore follows the rules we’ll mention below).

whole hundreds, thousands, etc

For whole hundreds, thousands, millions (basically, anything ending with at least two zeros), the **counted noun** is:

- singular
- مجرور (because it forms an إضافة with the number)

Examples:

خَمسُمِئةِ (/خَمسُ مِئةِ) طِفلٍ

*500 children*

ثَمانِيَةُ آلافِ شَجَرَةٍ

*8000 trees*

ثَمانِيَةُ آلافٍ وَخَمسُمِئَةِ صورةٍ

*8500 pictures*

اِثنانِ وَأَربَعونَ أَلفَ قِطارٍ

*42,000 trains*

مِليونا مِرآةٍ

*2,000,000 mirrors*

compound numbers

The last category! (Well, it’s more of a note really…)

When we have a number above 100 that includes tens or units, we use the **last two digits** to work out which set of rules to use.

For example, for the number 28,0**61**, we’d use the same rules as we would for the number 61: the number is the same gender as the counted noun, and the counted noun is singular and منصوب.

And if we had the number 5,000,0**05**, we’d use the set of rules for the number 5: the number is the opposite gender to that of the counted noun, and the counted noun is plural and مجرور.

…and, *exhale*! That’s it, you’ve reached the end of the rules!

(I need a lie-down after that.)

great post! stuff like this is vital for any serious student of arabic! thank you!

You’re totally welcome! I’m glad I have this as a reference for myself now too 😅

Excellent straight forward concise explanation of a bit confusing subject. Well done.

I’ve made a little tool for converting numbers to its arabic text representation applying all rules you have mentioned and a little more. tafqit.com

Hi Sami 😄 I actually mentioned tafqit.com near the top of the post – thanks for creating such a brilliant tool, I use it quite often!

oops sorry did not notice it at first..

I really appreciate you mentioning it and liking it. Please let me know if you have any feedback or think of more features.

Thanks
