Arabic Numbers 3-10: The Gender Flip Rule

For numbers 3-10, flip the number's gender to oppose the singular noun's gender and use a plural noun.

Grammar Rule in 30 Seconds

For numbers 3-10, the number's gender must be the exact opposite of the singular noun's gender.

  • Identify the singular form of the noun: 'pen' (qalam) is masculine.
  • If the noun is masculine, use the feminine form of the number (e.g., thalathat aqlam).
  • If the noun is feminine, use the masculine form of the number (e.g., thalathu sa'at).
Number (Opposite Gender) + Noun (Plural Genitive)

Overview

Arabic numbers ثلاثة (thalāthah) through عشرة (ʿasharah), when counting nouns, exhibit a phenomenon known as gender polarity or reverse agreement. This means the grammatical gender of the number (masculine or feminine) will be the opposite of the grammatical gender of the noun being counted. This rule is a cornerstone of Arabic numerical grammar at the B1 level and reflects a distinct linguistic structure compared to numbers 1, 2, and those beyond 10.

Historically, this inverse agreement likely stems from an ancient Semitic linguistic convention where numbers 3-10 were often treated as collective feminine nouns. Consequently, the items being counted would then grammatically differentiate themselves by taking the masculine form, or vice-versa, creating this counter-intuitive agreement pattern. Mastering this rule is crucial for accurate and authentic Modern Standard Arabic (MSA) expression, distinguishing an intermediate learner from a novice.

How This Grammar Works

The fundamental principle of Arabic numbers 3-10 is that the gender of the number is determined by the singular form of the noun being counted, not its plural form. This is a critical distinction because Arabic frequently employs "broken plurals" (جُمُوع التَّكْسِير, jumūʿ at-taksīr), where the plural form does not necessarily retain the gender indicators of its singular, potentially leading to misidentification.
For example, the noun كِتَاب (kitāb – book) is masculine. Its plural is كُتُب (kutub – books). When counting books, you refer to the singular كِتَاب as masculine, thus requiring the feminine form of the number.
Conversely, سَيَّارَة (sayyārah – car) is feminine (indicated by the تَاء مَرْبُوطَة – tāʾ marbūṭah ة). Its plural is سَيَّارَات (sayyārāt – cars). When counting cars, the singular سَيَّارَة dictates the use of the masculine form of the number.
Furthermore, numbers 3-10 form an إِضَافَة (iḍāfah) construction, commonly translated as a "genitive annexation" or "possessive phrase." In this structure, the number acts as the مُضَاف (muḍāf – first term), and the noun being counted acts as the مُضَاف إِلَيْه (muḍāf ilayh – second term). Consequently, the counted noun must always be in the plural form and in the genitive case (مَجْرُور, majrūr). It must also remain indefinite (without الـ, al- prefix) unless the entire iḍāfah phrase is made definite through other means.
Consider أَرْبَعَةُ رِجَالٍ (arbaʿatu rijālin – four men). The number أَرْبَعَة (feminine) opposes the singular رَجُل (rajul – man, masculine). The noun رِجَالٍ is the plural of رَجُل, and it is in the genitive case.
Similarly, ثَلَاثُ نِسَاءٍ (thalāthu nisāʾin – three women). The number ثَلَاث (masculine) opposes the singular امْرَأَة (imraʾah – woman, feminine). The noun نِسَاءٍ is the plural of امْرَأَة, and it is in the genitive case.

Formation Pattern

1
To correctly form a numerical expression with numbers 3-10, follow these steps:
2
Identify the Noun to be Counted: Determine the specific item or group of items you intend to quantify. For instance, if you want to say "seven books," your noun is "books." كُتُب (kutub).
3
Determine the Singular Form: Ascertain the singular form of that noun. The singular of كُتُب is كِتَاب (kitāb).
4
Establish the Singular Noun's Grammatical Gender: Identify whether the singular noun is masculine or feminine. كِتَاب is masculine, as it lacks the ة (tāʾ marbūṭah) and refers to an inanimate object without inherent natural gender that would supersede grammatical gender.
5
Select the Opposite Gender Form of the Number: Based on the singular noun's gender, choose the number form that has the opposite gender. For a masculine noun like كِتَاب, you must use the feminine form of the number seven, which is سَبْعَة (sabʿah).
6
Place the Number Before the Noun: The number always precedes the counted noun in this construction.
7
Ensure the Noun is Plural and Genitive: The counted noun must be in its plural form and marked with the genitive case ending (ـٍ or ـَينِ for the sound masculine plural, but typically ـٍ for broken plurals). For كُتُب, this would be كُتُبٍ (kutubin).
8
Therefore, "seven books" becomes سَبْعَةُ كُتُبٍ (sabʿatu kutubin).
9
Here are the masculine and feminine forms of numbers 3-10:
10
| Number | Masculine Form (used with feminine singular nouns) | Feminine Form (used with masculine singular nouns) |
11
| :----- | :----------------------------------------------- | :----------------------------------------------- |
12
| 3 | ثَلَاث (thalāth) | ثَلَاثَة (thalāthah) |
13
| 4 | أَرْبَع (arbaʿ) | أَرْبَعَة (arbaʿah) |
14
| 5 | خَمْس (khams) | خَمْسَة (khamsah) |
15
| 6 | سِتّ (sitt) | سِتَّة (sittah) |
16
| 7 | سَبْع (sabʿ) | سَبْعَة (sabʿah) |
17
| 8 | ثَمَانٍ (thamānin) or ثَمَانِي (thamānī) | ثَمَانِيَة (thamāniyah) |
18
| 9 | تِسْع (tisʿ) | تِسْعَة (tisʿah) |
19
| 10 | عَشْر (ʿashar) | عَشَرَة (ʿasharah) |
20
Special Note on Number 8: The number ثَمَانِي (thamānī) when counting feminine singular nouns is a اسْم مَنْقُوص (ism manqūṣ – defective noun). This means its final ي (yāʾ) is dropped in the nominative and genitive cases when indefinite, appearing as ثَمَانٍ (thamānin), and the نون (nūn) is vocalized with a kasra tanwin. In the accusative case, it retains the ي and takes a fatḥah, ثَمَانِيَ (thamāniya). When definite, or مُضَاف to a definite noun, the ي is always present. For B1 learners, understanding the form ثَمَانٍ is important for passive recognition, while ثَمَانِيَة for masculine nouns remains straightforward.

Gender & Agreement

Understanding grammatical gender in Arabic nouns is paramount for this rule. Nouns are inherently masculine or feminine. Natural gender applies to beings with biological sex (e.g., رَجُل – man is masculine, امْرَأَة – woman is feminine).
For most other nouns, especially inanimate objects, grammatical gender is assigned. The presence of تَاء مَرْبُوطَة (ة) at the end of a singular noun almost invariably signifies it as feminine (e.g., مَدْرَسَة – madrasah, school; كَلِمَة – kalimah, word).
The reverse agreement rule dictates that if the singular noun is masculine, the number 3-10 will take its feminine form (usually ending in ة). If the singular noun is feminine, the number 3-10 will take its masculine form (without ة).
Example with a masculine singular noun (قَلَم – qalam, pen):
  • Singular: قَلَم (masculine)
  • Number needed (e.g., five): خَمْسَة (feminine)
  • Plural of قَلَم: أَقْلَام (aqlām)
  • Construction: خَمْسَةُ أَقْلَامٍ (khamsatu aqlāmin – five pens).
Here, خَمْسَةُ is the مُضَاف (nominative case, as it's the subject) and أَقْلَامٍ is the مُضَاف إِلَيْه (genitive case).
Example with a feminine singular noun (صُورَة – ṣūrah, picture):
  • Singular: صُورَة (feminine)
  • Number needed (e.g., three): ثَلَاث (masculine)
  • Plural of صُورَة: صُوَر (ṣuwar)
  • Construction: ثَلَاثُ صُوَرٍ (thalāthu ṣuwarin – three pictures).
Here, ثَلَاثُ is the مُضَاف (nominative case) and صُوَرٍ is the مُضَاف إِلَيْه (genitive case).
It is imperative to distinguish this from the agreement rules for adjectives or numbers 1 and 2, which always agree in gender with the noun they modify. The iḍāfah structure is key to understanding why the counted noun is plural and genitive, a consequence of the number acting as a governing term.

When To Use It

This rule applies universally in Modern Standard Arabic (MSA) whenever you are counting 3 to 10 discrete items. It is a mandatory grammatical feature in formal speech, written texts, academic discourse, and news media. You will encounter and employ this pattern in various contexts:
  • Counting objects: عَشَرَةُ كُتُبٍ (ʿasharatu kutubin – ten books), سِتُّ سَيَّارَاتٍ (sittu sayyārātin – six cars).
  • Quantifying people: أَرْبَعَةُ طُلَّابٍ (arbaʿatu ṭullābin – four male students), خَمْسُ طَالِبَاتٍ (khamsu ṭālibātin – five female students).
  • Specifying time units: ثَلَاثَةُ أَيَّامٍ (thalāthatu ayyāmin – three days), سَبْعُ سَاعَاتٍ (sabʿu sāʿātin – seven hours).
  • Referring to abstract concepts: ثَمَانِيَةُ مَبَادِئَ (thamāniyatu mabādiʾa – eight principles), تِسْعُ خُطُوَاتٍ (tisʿu khuṭuwātin – nine steps).
Contrast with other number rules:
  • Numbers 1 and 2: These numbers function as adjectives. They agree in gender with the noun and typically follow it. For example, كِتَابٌ وَاحِدٌ (kitābun wāḥidun – one book, masc-masc) and سَيَّارَةٌ وَاحِدَةٌ (sayyāratun wāḥidah – one car, fem-fem). For two, كِتَابَانِ اثْنَانِ (kitābāni ithnāni – two books, masc-masc) and سَيَّارَتَانِ اثْنَتَانِ (sayyāratāni ithnatāni – two cars, fem-fem).
  • Numbers 11-19: These compound numbers have their own rules. The noun counted by 11-99 is always singular and in the accusative case (مَنْصُوب, manṣūb). The unit part (1-9) of the number still observes gender agreement with the noun for 1-2, and reverse agreement for 3-9, while عَشَرَ (ʿashara) generally agrees with the noun. For instance, أَحَدَ عَشَرَ كِتَابًا (aḥada ʿashara kitāban – eleven books) or ثَلَاثَةَ عَشَرَ كِتَابًا (thalāthata ʿashara kitāban – thirteen books).
Therefore, the gender flip rule is specific to the 3-10 range and is indispensable for constructing grammatically correct Arabic sentences within this numerical scope. Ignoring it marks a clear deviation from MSA standards.

Common Mistakes

Learners at the B1 level often encounter specific pitfalls when applying the gender flip rule. Awareness of these common errors facilitates their avoidance:
  1. 1Misidentifying Noun Gender from Plural Forms: This is arguably the most frequent mistake. Arabic broken plurals (جُمُوع التَّكْسِير) can be deceptive. For instance, جُنَيْهَات (junayhāt – pounds, currency) appears feminine due to the final ـَات ending. However, its singular, جُنَيْه (junayh), is masculine. Therefore, to say "five pounds," you must use the feminine form of five: خَمْسَةُ جُنَيْهَاتٍ (khamsatu junayhāt – five pounds), not خَمْسُ جُنَيْهَاتٍ. Always revert to the singular noun to verify its gender.
  2. 2Incorrect إِضَافَة (Idafa) Construction: Forgetting that the counted noun must be plural, indefinite, and in the genitive case. Common errors include:
  • Using a singular noun: ثَلَاثَةُ كِتَابٍ (incorrect) instead of ثَلَاثَةُ كُتُبٍ.
  • Making the noun definite: أَرْبَعَةُ الْكُتُبِ (incorrect) instead of أَرْبَعَةُ كُتُبٍ. The مُضَاف إِلَيْه in this specific numeral iḍāfah typically remains indefinite.
  • Incorrect case ending: خَمْسَةُ كُتُبٌ (incorrect, nominative) or خَمْسَةُ كُتُبًا (incorrect, accusative) instead of خَمْسَةُ كُتُبٍ (genitive).
  1. 1Applying the Gender Flip to Numbers 1 or 2: Numbers 1 and 2 follow standard adjectival agreement rules, where they match the noun's gender and typically follow it. Confusing this with the 3-10 rule leads to errors like وَاحِدَةُ كِتَابٍ (incorrect, should be كِتَابٌ وَاحِدٌ).
  2. 2Neglecting the Case of the Number Itself: While the noun is always genitive, the number (as the مُضَاف) will take its case ending based on its grammatical function in the sentence (nominative ـُ, accusative ـَ, or genitive ـِ). For example, رَأَيْتُ ثَلَاثَةَ رِجَالٍ (raʾaytu thalāthata rijālin – I saw three men), where ثَلَاثَةَ is in the accusative case because it's the direct object.
  3. 3Mismanaging Number 8 (ثماني/ثمانٍ): The defective noun behavior of ثَمَانِي (thamānī) can be challenging. Learners often forget to drop the ي and use ن tanwin in the indefinite nominative/genitive cases when counting feminine nouns. For instance, ثَمَانٍ بَنَاتٍ (thamānin banātin – eight girls) instead of ثَمَانِي بَنَاتٍ (incorrect).
Consistently reviewing the singular noun's gender and the iḍāfah structure will mitigate most of these common errors.

Common Collocations

The numbers 3-10 frequently appear with specific nouns, forming common phrases that are useful to memorize. These collocations demonstrate the gender flip rule in practical application:
  • Time:
  • ثَلَاثَةُ أَيَّامٍ (thalāthatu ayyāmin – three days) - يَوْم (masc) -> ثَلَاثَة (fem)
  • أَرْبَعُ سَاعَاتٍ (arbaʿu sāʿātin – four hours) - سَاعَة (fem) -> أَرْبَع (masc)
  • خَمْسَةُ أَشْهُرٍ (khamsatu ashhurin – five months) - شَهْر (masc) -> خَمْسَة (fem)
  • سِتُّ دَقَائِقَ (sittu daqāʾiqa – six minutes) - دَقِيقَة (fem) -> سِتّ (masc)
  • سَبْعُ سَنَوَاتٍ (sabʿu sanawātin – seven years) - سَنَة (fem) -> سَبْع (masc)
  • People:
  • ثَلَاثَةُ رِجَالٍ (thalāthatu rijālin – three men) - رَجُل (masc) -> ثَلَاثَة (fem)
  • أَرْبَعُ نِسَاءٍ (arbaʿu nisāʾin – four women) - امْرَأَة (fem) -> أَرْبَع (masc)
  • خَمْسَةُ أَطْفَالٍ (khamsatu aṭfālin – five children) - طِفْل (masc) -> خَمْسَة (fem)
  • سَبْعَةُ طُلَّابٍ (sabʿatu ṭullābin – seven male students) - طَالِب (masc) -> سَبْعَة (fem)
  • Objects/Concepts:
  • ثَلَاثَةُ كُتُبٍ (thalāthatu kutubin – three books) - كِتَاب (masc) -> ثَلَاثَة (fem)
  • أَرْبَعُ قِصَصٍ (arbaʿu qiṣaṣin – four stories) - قِصَّة (fem) -> أَرْبَع (masc)
  • خَمْسَةُ مَبَانٍ (khamsatu mabānin – five buildings) - مَبْنًى (masc) -> خَمْسَة (fem)
  • عَشَرَةُ أَقْلَامٍ (ʿasharatu aqlāmin – ten pens) - قَلَم (masc) -> عَشَرَة (fem)
  • عَشْرُ جَامِعَاتٍ (ʿashru jāmiʿātin – ten universities) - جَامِعَة (fem) -> عَشْر (masc)
These common phrases serve as excellent models for applying the gender flip rule and internalizing its patterns.

Real Conversations

While the gender flip rule for numbers 3-10 is strictly observed in formal written and spoken Modern Standard Arabic, its application in everyday casual conversations and various Arabic dialects (العَامِّيَّة, al-ʿāmmiyyah) can vary significantly. In many dialects, the gender distinction for numbers is often simplified or completely dropped, with a single form of the number used irrespective of the noun's gender, or with numbers directly modifying nouns without the iḍāfah structure.

However, for university students and young professionals learning Arabic, a strong command of MSA is essential for academic pursuits, professional communication, and understanding media across the Arab world. Even if a native speaker in a casual setting might simplify, using correct MSA numerical forms will always be understood and is a mark of high proficiency. Consider these examples:

1. Formal Written/Professional Context (MSA):

- Email: عَزِيزِي مُدِيرُ الْمَشْرُوعِ، لَقَدْ تَمَّ الْعَمَلُ عَلَى ثَلَاثَةِ تَقَارِيرَ حَتَّى الْآنَ.

(ʿazīzī mudīru al-mashrūʿi, laqad tamma al-ʿamalu ʿalā thalāthati taqārīra ḥattā al-āna.)

"Dear Project Manager, three reports have been worked on so far."

(تَقْرِير – taqrīr, report, masculine singular → ثَلَاثَة – feminine number. تَقَارِيرَ is plural genitive by a different rule for non-diptotes, but ثَلَاثَةِ is genitive due to عَلَى.)

- News Report: تَلَقَّتِ الشَّرِكَةُ خَمْسَةَ عُقُودٍ جَدِيدَةٍ هَذَا الْعَامَ.

(talaqqati ash-sharīkatu khamsata ʿuqūdin jadīdatihn hādhā al-ʿāma.)

"The company received five new contracts this year."

(عَقْد – ʿaqd, contract, masculine singular → خَمْسَةَ – feminine number, accusative as direct object.)

2. Everyday Formal/Educational Context (MSA):

- Teacher to Students: لَدَيْنَا سِتُّ طَالِبَاتٍ وَأَرْبَعَةُ طُلَّابٍ فِي الصَّفِّ الْجَدِيدِ.

(ladaynā sittu ṭālibātin wa arbaʿatu ṭullābin fī aṣ-ṣaffi al-jadīdi.)

"We have six female students and four male students in the new class."

(طَالِبَة – ṭālibah, female student, feminine singular → سِتُّ – masculine number. طَالِب – ṭālib, male student, masculine singular → أَرْبَعَةُ – feminine number.)

- Traveler asking for directions: هَلْ يُمْكِنُكَ أَنْ تُخْبِرَنِي بِكَمْ تَبْعُدُ الْمَحَطَّةُ؟ خَمْسُ دَقَائِقَ سَيْرًا عَلَى الْأَقْدَامِ؟

(hal yumkinuka an tukhbiranī bikam tabʿudu al-maḥaṭṭatu? khamsu daqāʾiqa sayran ʿalā al-aqdāmi?)

"Can you tell me how far the station is? Five minutes walking?"

(دَقِيقَة – daqīqah, minute, feminine singular → خَمْسُ – masculine number.)

While conversational Arabic might abbreviate or simplify, the educated speaker, especially in more formal or written exchanges, will consistently apply these rules. Understanding this distinction allows you to adapt your language according to the social and communicative context.

Quick FAQ

Q1: Why does Arabic have this seemingly counter-intuitive gender flip for numbers 3-10?
A1: The gender flip is a vestige of ancient Semitic linguistic patterns. Linguists theorize that numbers 3-10 were historically treated as collective nouns with an inherent feminine grammatical gender (e.g., ثَلَاثَة meaning "a group of three"). When such a collective feminine noun governs the items being counted (which themselves would be masculine), a form of polarity arises to differentiate the governor from the governed.
This is a characteristic feature reflecting the deep structure of the language, rather than an arbitrary rule.
Q2: Does the number 10 (عَشَرَة/عَشْر) always follow the gender flip rule?
A2: Yes, when عَشَرَة or عَشْر is used as a standalone number (i.e., not as part of a compound number like 13 or 14), it strictly follows the gender flip rule. For example, عَشَرَةُ كُتُبٍ (ʿasharatu kutubin – ten books) where كِتَاب (masculine) dictates عَشَرَة (feminine), and عَشْرُ سَيَّارَاتٍ (ʿashru sayyārātin – ten cars) where سَيَّارَة (feminine) dictates عَشْر (masculine). However, when عَشَرَ is part of a compound number (11-19), its behavior changes, and it typically agrees in gender with the noun, while the unit part (3-9) still flips.
Q3: How can I reliably determine the singular noun's gender, especially with broken plurals?
A3: The most reliable method is to always consult the singular form of the noun. If the singular noun ends with تَاء مَرْبُوطَة (ة), it is almost certainly feminine. If it does not, it is generally masculine, unless it refers to a naturally feminine being.
When in doubt, a reliable Arabic dictionary will list the singular form and often indicate its gender. Over time, as you encounter more vocabulary, you will begin to recognize patterns and commit common plurals and their singular genders to memory.
Q4: Is this rule applied differently in various Arabic dialects (العَامِّيَّة)?
A4: Yes, in many Arabic dialects, the strict gender polarity of numbers 3-10 is often relaxed or even absent. Speakers may use a single form for the number regardless of the noun's gender, or simplify the grammatical structure (e.g., using a singular noun or omitting the genitive case). However, for any formal context, written communication, or academic work in Arabic, adherence to the MSA rule is expected and signifies grammatical correctness.
Learning the MSA rule provides a foundation that allows you to understand and produce formal Arabic, and later, to recognize and adapt to dialectal variations.

Write the singular noun first, then the number.

ثلاثة قلم ثلاثة أقلام

Practice the most common nouns (pen, book, car, student) until the gender is automatic.

خمسة سيارة خمس سيارات

Learn the gender along with the noun.

Learning 'qalam' Learning 'qalam (masculine)'

Pronunciation

Thalathatu aqlam

Ta-marbuta

The 'ة' is pronounced as 't' when followed by a noun in a construct state.

Statement

ثلاثةُ أقلامٍ ↓

Falling intonation for declarative sentences.

Memorize It

Mnemonic

Remember 'Opposites Attract'. If the noun is a boy, the number must be a girl (add ta-marbuta).

Visual Association

Imagine a seesaw. On one side is the noun, on the other is the number. When the noun is heavy (masculine), the number must be light (feminine) to balance it.

Rhyme

Noun is boy, number gets a toy (ta-marbuta). Noun is girl, number is plain as a pearl.

Story

Ahmed went to the shop. He wanted 3 pens (masculine). He asked for 'thalathat aqlam'. Then he wanted 3 watches (feminine). He asked for 'thalathu sa'at'. He kept flipping the gender all day long.

Challenge

Count 5 items in your room right now using the correct gender flip.

Cultural Notes

In many dialects, the gender flip rule is often ignored in casual speech, but it is strictly maintained in formal media.

Formal usage is preferred in business and government settings.

Colloquial speech often simplifies numbers.

The gender polarity in Arabic numerals is an ancient Semitic feature, found in languages like Hebrew and Ge'ez.
