Lesson

1. What Are Number Nouns?

أَسْمَاءُ الْعَدَدِ
A number noun states a quantity.
For example, ثَلَاثَةُ طُلَّابٍ means three students.
The numeral gives the count; the second noun names what is counted.

2. The Twelve Basic Number Words

أُصُولُ الْعَدَدِ اثْنَتَا عَشْرَةَ كَلِمَةً
The author lists 12 basic number words:
وَاحِدَةٌ، اثْنَانِ، ثَلَاثَةٌ، أَرْبَعَةٌ، خَمْسَةٌ، سِتَّةٌ
سَبْعَةٌ، ثَمَانِيَةٌ، تِسْعَةٌ، عَشَرَةٌ، مِائَةٌ، أَلْفٌ
They form the basis for derived number expressions.

3. Three Checks Before Choosing a Numeral

Check three things:
1. Is the counted noun masculine or feminine in the singular?
2. Which number range is involved?
3. What case and number must the counted noun take?

4. Gender Comes from the Singular Noun

كِتَابٌ — مَذَكَّرٌ
صَفْحَةٌ — مُؤَنَّثَةٌ
Kitāb is masculine; its plural is kutub.
Ṣafḥah is feminine; its plural is ṣafaḥāt.
For number agreement, inspect the singular form of the counted noun.

5. One: Gender Agreement

رَجُلٌ وَاحِدٌ
امْرَأَةٌ وَاحِدَةٌ
One man — one woman.
Wāḥid agrees with a masculine noun; wāḥidah with a feminine noun.
The number 1 follows the noun’s gender.

6. Two: Gender Agreement

رَجُلَانِ اثْنَانِ
امْرَأَتَانِ اثْنَتَانِ
Two men — two women.
Ithnān is masculine; ithnatān is feminine.
The numeral 2 agrees with the counted noun.

7. One and Two Usually Describe the Noun

كِتَابٌ وَاحِدٌ
كِتَابَانِ اثْنَانِ
Kitābun already means one book; wāḥidun describes or confirms it.
Kitābāni is already dual; ithnāni reinforces the number.
In these patterns the following noun is not an independent number-tamyīz.

8. Three to Ten: Reverse Gender

ثَلَاثَةُ رِجَالٍ
ثَلَاثُ نِسْوَةٍ
Three men — three women.
With a masculine counted noun, the numeral takes tāʾ marbūṭah.
With a feminine counted noun, it normally lacks it.
This is the reverse of the 1–2 pattern.

9. Masculine Nouns: Four Examples

ثَلَاثَةُ رِجَالٍ
أَرْبَعَةُ كُتُبٍ
خَمْسَةُ أَقْلَامٍ
سِتَّةُ طُلَّابٍ
Three men, four books, five pens, six students.
Their singular nouns are masculine, so each numeral bears the feminine ending.
These are four examples from the 3–10 range.

10. Feminine Nouns: Four Examples

ثَلَاثُ بَنَاتٍ
أَرْبَعُ صَفَحَاتٍ
خَمْسُ غُرَفٍ
سِتُّ شَجَرَاتٍ
Three girls, four pages, five rooms, six trees.
Their singular counted nouns are feminine, so the numerals lack tāʾ marbūṭah.
These are four examples from the 3–10 range.

11. Seven to Ten: Both Genders

سَبْعَةُ رِجَالٍ — سَبْعُ نِسْوَةٍ
ثَمَانِيَةُ رِجَالٍ — ثَمَانِي نِسْوَةٍ
تِسْعَةُ رِجَالٍ — تِسْعُ نِسْوَةٍ
عَشَرَةُ رِجَالٍ — عَشْرُ نِسْوَةٍ
Seven, eight, nine, ten men — and the same counts of women.
Each masculine-noun example takes the opposite-gender numeral with -ah; the feminine examples do not.
This completes the 3–10 range.

12. Counted Noun after Three to Ten

ثَلَاثَةُ كُتُبٍ
خَمْسُ صَفَحَاتٍ
Kutubin and ṣafaḥātin are plural genitives.
The numeral is the first member of an iḍāfah, and the counted noun is its genitive second member.

13. Case of a 3–10 Numeral

جَاءَ ثَلَاثَةُ طُلَّابٍ.
رَأَيْتُ ثَلَاثَةَ طُلَّابٍ.
مَرَرْتُ بِثَلَاثَةِ طُلَّابٍ.
Three students arrived; I saw three students; I passed by three students.
The numeral changes with syntactic case.
The counted noun remains genitive because it is the muḍāf ilayh.

14. Eleven: Both Parts Agree in Gender

أَحَدَ عَشَرَ رَجُلًا
إِحْدَى عَشْرَةَ امْرَأَةً
Eleven men — eleven women.
In 11 both parts match the counted noun’s gender.
Its counted noun is singular accusative.

15. Twelve: Both Parts Agree

اثْنَا عَشَرَ رَجُلًا
اثْنَتَا عَشْرَةَ امْرَأَةً
Twelve men — twelve women.
The masculine form is ithnā ʿashara, the feminine ithnatā ʿashrata.
Both parts follow the counted noun’s gender.

16. Twelve: The First Part Declines

جَاءَ اثْنَا عَشَرَ طَالِبًا.
رَأَيْتُ اثْنَيْ عَشَرَ طَالِبًا.
مَرَرْتُ بِاثْنَيْ عَشَرَ طَالِبًا.
Twelve students came; I saw twelve; I passed by twelve.
The first part has dual-style case endings: ithnā (nom.) and ithnay (acc./gen.).
The second part is fixed; the counted noun is singular accusative.

17. Feminine Twelve Also Declines

جَاءَتِ اثْنَتَا عَشْرَةَ طَالِبَةً.
رَأَيْتُ اثْنَتَيْ عَشْرَةَ طَالِبَةً.
Twelve female students arrived; I saw twelve female students.
The first part changes from ithnatā to ithnatay, while ʿashrata remains fixed.
Ṭālibatan is the singular accusative specification.

18. Thirteen to Nineteen: Opposite, Then Matching

ثَلَاثَةَ عَشَرَ رَجُلًا
ثَلَاثَ عَشْرَةَ امْرَأَةً
Thirteen men — thirteen women.
For 13–19 the unit digit has reverse gender; the tens part agrees in gender.
The counted noun is singular accusative.

19. Thirteen to Sixteen: Paired Examples

ثَلَاثَةَ عَشَرَ رَجُلًا — ثَلَاثَ عَشْرَةَ امْرَأَةً
أَرْبَعَةَ عَشَرَ رَجُلًا — أَرْبَعَ عَشْرَةَ امْرَأَةً
خَمْسَةَ عَشَرَ رَجُلًا — خَمْسَ عَشْرَةَ امْرَأَةً
سِتَّةَ عَشَرَ رَجُلًا — سِتَّ عَشْرَةَ امْرَأَةً
Pairs for 13, 14, 15 and 16 men/women.
The first part reverses gender, and the second matches.
The counted noun remains singular accusative.

20. Seventeen to Nineteen: Remaining Examples

سَبْعَةَ عَشَرَ رَجُلًا — سَبْعَ عَشْرَةَ امْرَأَةً
ثَمَانِيَةَ عَشَرَ رَجُلًا — ثَمَانِيَ عَشْرَةَ امْرَأَةً
تِسْعَةَ عَشَرَ رَجُلًا — تِسْعَ عَشْرَةَ امْرَأَةً
Seventeen, eighteen and nineteen men and women.
The same two-part agreement rule applies.
This completes the seven numbers 13–19.

21. Most Teen Compounds Are Fixed on Fatḥah

جَاءَ أَحَدَ عَشَرَ رَجُلًا.
رَأَيْتُ ثَلَاثَةَ عَشَرَ رَجُلًا.
The components of 11 and 13–19 are generally built on fatḥah.
The number’s grammatical position can change without changing those endings.
The first part of 12 is an important exception.

22. Twenty to Ninety: Same Form for Both Genders

عِشْرُونَ رَجُلًا
عِشْرُونَ امْرَأَةً
Twenty men — twenty women.
The tens numeral remains the same for both genders.
This holds for the decades through ninety.

23. All Eight Decades

عِشْرُونَ — ثَلَاثُونَ — أَرْبَعُونَ — خَمْسُونَ
سِتُّونَ — سَبْعُونَ — ثَمَانُونَ — تِسْعُونَ
These are the eight decade words: 20–90.
They are called ʿuqūd and do not change form according to gender of the counted noun.

24. Case Endings of the Decades

جَاءَ عِشْرُونَ طَالِبًا.
رَأَيْتُ عِشْرِينَ طَالِبًا.
مَرَرْتُ بِعِشْرِينَ طَالِبًا.
ʿIshrūna in the nominative; ʿishrīna in the accusative and genitive.
The following ṭāliban is singular accusative in all three sentences.

25. Twenty-One: The Unit Agrees

أَحَدٌ وَعِشْرُونَ رَجُلًا
إِحْدَى وَعِشْرُونَ امْرَأَةً
Twenty-one men — twenty-one women.
The unit part follows the gender of 1; the tens word stays unchanged.
The counted noun is singular accusative.

26. Twenty-Two: The Unit Agrees

اثْنَانِ وَعِشْرُونَ رَجُلًا
اثْنَتَانِ وَعِشْرُونَ امْرَأَةً
Twenty-two men — twenty-two women.
The unit follows the gender and case pattern of 2.
In oblique cases use ithnayn / ithnatayn; the decade does not depend on gender.

27. Twenty-Three to Twenty-Nine: Reverse Gender

ثَلَاثَةٌ وَعِشْرُونَ رَجُلًا
ثَلَاثٌ وَعِشْرُونَ امْرَأَةً
Twenty-three men — twenty-three women.
The unit part 3–9 reverses gender while the tens part stays the same.

28. Ninety-Nine Follows the Same Pattern

تِسْعَةٌ وَتِسْعُونَ رَجُلًا
تِسْعٌ وَتِسْعُونَ امْرَأَةً
Ninety-nine men — ninety-nine women.
The unit 9 reverses gender; the decade is unchanged.
This pattern extends to 99.

29. Case in Compound Numbers Joined by Wāw

جَاءَ ثَلَاثَةٌ وَعِشْرُونَ رَجُلًا.
رَأَيْتُ ثَلَاثَةً وَعِشْرِينَ رَجُلًا.
Twenty-three men arrived; I saw twenty-three men.
Nominative: thalāthatun wa-ʿishrūna.
Accusative: thalāthatan wa-ʿishrīna.
The singular accusative specification remains unchanged.

30. One Hundred: No Gender Difference

مِائَةُ رَجُلٍ
مِائَةُ امْرَأَةٍ
One hundred men — one hundred women.
Miʾah is used with either gender.
The counted noun is singular genitive after it.

31. Two Hundred and Three Hundred

مِائَتَا رَجُلٍ
ثَلَاثُ مِائَةِ رَجُلٍ
Two hundred men — three hundred men.
Miʾatā is the dual construct form; thalāthu miʾati combines 3 and 100 by iḍāfah.
The ultimate counted noun stays singular genitive.

32. One Thousand: No Gender Difference

أَلْفُ رَجُلٍ
أَلْفُ امْرَأَةٍ
One thousand men — one thousand women.
Alf is gender-neutral.
The counted noun is singular genitive.

33. Two Thousand and Three Thousand

أَلْفَا رَجُلٍ
ثَلَاثَةُ آلَافِ رَجُلٍ
Two thousand men — three thousand men.
Alfā is the dual construct; thalāthatu ālāfi uses a plural genitive “thousands”.
The final noun rajulin is singular genitive, as it is after a single alf.

34. Larger Numbers Reuse the Rules

مِائَةٌ وَخَمْسَةٌ وَأَرْبَعُونَ رَجُلًا
One hundred and forty-five men.
100 is followed by 45; the unit 5 reverses gender and the tens remain invariant.
The final specification rajulan is singular accusative.

35. The Four Main Counted-Noun Patterns

رَجُلٌ وَاحِدٌ
ثَلَاثَةُ رِجَالٍ
أَحَدَ عَشَرَ رَجُلًا
مِائَةُ رَجُلٍ
1–2: numeral normally functions adjectivally or as reinforcement.
3–10: usually plural genitive (except constructions such as three hundred).
11–99: singular accusative.
100 and 1000: singular genitive.

36. Specification vs. Iḍāfah

ثَلَاثَةُ طُلَّابٍ
عِشْرُونَ طَالِبًا
مِائَةُ طَالِبٍ
Ṭullābin after 3: plural genitive in iḍāfah.
Ṭāliban after 20: singular accusative tamyīz.
Ṭālibin after 100: singular genitive in iḍāfah.

37. Read the Whole Phrase in a Sentence

قَرَأْتُ أَرْبَعَةَ كُتُبٍ.
قَرَأْتُ أَرْبَعَ عَشْرَةَ صَفْحَةً.
I read four books; I read fourteen pages.
Kitāb is masculine, so 4 is arbaʿata with plural genitive kutubin.
Ṣafḥah is feminine, so 14 is arbaʿa ʿashrata with singular accusative ṣafḥatan.

38. Do Not Confuse Gender and Case

ثَلَاثُ صَفَحَاتٍ
رَأَيْتُ ثَلَاثَ صَفَحَاتٍ
Thalāth is the correct gender form for feminine pages in both examples.
It takes nominative or accusative case according to syntax.
Gender choice and case marking must be decided independently.

39. Correcting Four Common Mistakes

ثَلَاثَةُ رِجَالٍ — ثَلَاثُ نِسْوَةٍ
عِشْرُونَ رَجُلًا — مِائَةُ رَجُلٍ
Avoid four errors:
1. Misapplying reverse gender in 3–10.
2. Using singular accusative after 3–10.
3. Using plural genitive after a decade.
4. Using singular accusative after 100.

40. Key Rules and Next Section
