Grammar Rule in 30 Seconds

To make people plural, add -uun for masculine or -aat for feminine to the singular noun.

  • Masculine people: Add -uun (e.g., muhandis -> muhandisuun).
  • Feminine people: Replace -ah with -aat (e.g., mu'allimah -> mu'allimaat).
  • These endings only apply to specific human nouns, not objects.
Singular + (uun/aat) = Plural People

Overview

In Arabic grammar, pluralization is highly systematic, yet it distinguishes significantly between human and non-human entities. When referring to groups of people, their professions, or their qualities, Arabic employs a specific set of plural patterns known as the Sound Plurals (الجموع السالمة – al-jumūʿ al-sālimah). This system reflects a linguistic reverence for human beings, treating their words with a structural integrity not afforded to inanimate objects or animals.

The term 'Sound' (سالم – sālim) literally means 'safe' or 'intact,' signifying that the original singular word's structure remains preserved, unlike Broken Plurals (جموع التكسير – jumūʿ al-taksīr) where the singular form is altered internally.

For A1 learners, understanding these Sound Plurals for people is foundational. It provides a reliable and predictable method for expanding your vocabulary from singular to plural without memorizing irregular forms. This rule is your entry point to accurately describing groups of individuals, their roles, and their characteristics, forming a cornerstone of effective communication in Arabic.

You will encounter these patterns constantly in everyday conversations, academic texts, and professional settings, making their mastery indispensable.

How This Grammar Works

Arabic noun and adjective agreement is deeply intertwined with gender and number. The Sound Plurals for people primarily divide into two categories: the Sound Masculine Plural (جمع المذكر السالم – jamʿ al-mudhakkar al-sālim) and the Sound Feminine Plural (جمع المؤنث السالم – jamʿ al-muʾannath al-sālim). These plurals are formed by adding specific suffixes to the singular form without internal modifications.
This contrasts sharply with English, which predominantly uses '-s' or '-es' for pluralization, or with Arabic Broken Plurals, which involve internal vowel changes or consonant additions, such as كِتَاب (kitāb – book) becoming كُتُب (kutub – books).
The linguistic principle behind Sound Plurals is the maintenance of clarity and the preservation of the word's original meaning and structure. By simply appending a suffix, the singular identity remains easily recognizable within the plural form. For instance, مُدَرِّس (mudarris – male teacher) directly transforms into مُدَرِّسُونَ (mudarrisūn – male teachers) by adding ـونَ.
This transparency makes Sound Plurals comparatively easier to learn and apply, especially for beginners. You will notice this predictability across numerous human-referring nouns and adjectives, solidifying your understanding as you encounter more vocabulary.
Arabic grammar employs grammatical cases (الحالات الإعرابية – al-ḥālāt al-iʿrābiyyah) to indicate a word's function in a sentence (e.g., subject, object, possessive). While A1 learners often focus on the nominative case (when the word is the subject), it is important to be aware that the Sound Masculine Plural has two forms based on these cases. The nominative form ends in ـُونَ (-ūna), while the accusative and genitive forms end in ـِينَ (-īna).
The Sound Feminine Plural, however, uses ـَاتٌ (-ātun) for nominative and ـَاتٍ (-ātin) for accusative and genitive, the difference being in the short vowel on the ت (tāʾ). Recognizing these different endings is crucial for accurate sentence construction, even if their full application is explored at later CEFR levels.

Formation Pattern

1
Forming the Sound Plurals for people follows a straightforward set of rules, depending on the gender of the singular noun or adjective. These patterns are highly regular and predictable, making them accessible even at the A1 level. The key is to identify the singular form and then apply the correct suffix. Mastery of these patterns will significantly expand your ability to describe groups of people in various contexts.
2
1. Sound Masculine Plural (جمع المذكر السالم – jamʿ al-mudhakkar al-sālim)
3
This plural is used for groups of male individuals or mixed groups of males and females. It is formed by adding specific suffixes to the singular masculine form.
4
| Case | Suffix | Example: مُهَنْدِس (muhandis – engineer) | Pronunciation |
5
|:------------|:--------|:----------------------------------------------|:----------------|
6
| Nominative (Subject) | ـُونَ | مُهَنْدِسُونَ (muhandisūna) | mu-han-di-sūn |
7
| Accusative (Object) | ـِينَ | مُهَنْدِسِينَ (muhandisīna) | mu-han-di-sīn |
8
| Genitive (Possessive/After Preposition) | ـِينَ | مُهَنْدِسِينَ (muhandisīna) | mu-han-di-sīn |
9
Example:
10
Singular: هَذَا مُدَرِّسٌ. (Hādhā mudarrisun – This is a teacher.)
11
Plural (Nominative): هَؤُلاَءِ مُدَرِّسُونَ. (Hāʾulāʾi mudarrisūna – These are teachers.)
12
Plural (Accusative/Genitive): رَأَيْتُ مُدَرِّسِينَ. (Raʾaytu mudarrisīna – I saw teachers.) / سَلَّمْتُ عَلَى مُدَرِّسِينَ. (Sallamtu ʿalā mudarrisīna – I greeted teachers.)
13
2. Sound Feminine Plural (جمع المؤنث السالم – jamʿ al-muʾannath al-sālim)
14
This plural is used exclusively for groups of female individuals. It is formed by first removing the تَاء مَرْبُوطَة (tāʾ marbūṭah – ة) from the singular feminine form, if present, and then adding ـَات (-āt).
15
| Case | Suffix | Example: مُعَلِّمَة (muʿallimah – female teacher) | Pronunciation |
16
|:------------|:--------|:---------------------------------------------|:----------------|
17
| Nominative (Subject) | ـَاتٌ | مُعَلِّمَاتٌ (muʿallimātun) | mu-ʿal-li-māt |
18
| Accusative (Object) | ـَاتٍ | مُعَلِّمَاتٍ (muʿallimātin) | mu-ʿal-li-māt |
19
| Genitive (Possessive/After Preposition) | ـَاتٍ | مُعَلِّمَاتٍ (muʿallimātin) | mu-ʿal-li-māt |
20
Example:
21
Singular: هَذِهِ طَالِبَةٌ. (Hādhihi ṭālibatun – This is a female student.)
22
Plural (Nominative): هَؤُلاَءِ طَالِبَاتٌ. (Hāʾulāʾi ṭālibātun – These are female students.)
23
Plural (Accusative/Genitive): قَابَلْتُ طَالِبَاتٍ. (Qābaltu ṭālibātin – I met female students.) / تَكَلَّمْتُ مَعَ طَالِبَاتٍ. (Takallamtu maʿa ṭālibātin – I spoke with female students.)
24
Key Steps for Formation:
25
Identify Gender: Determine if the singular word describes a male or female. This dictates which Sound Plural rule to apply.
26
Masculine: Add ـُونَ (nominative) or ـِينَ (accusative/genitive) to the end of the singular masculine noun/adjective.
27
Feminine: If the singular feminine word ends in ة, remove it. Then, add ـَات to the end of the modified (or original, if no ة) singular feminine noun/adjective.

Gender & Agreement

Arabic is a gendered language, and this grammatical feature extends profoundly to pluralization, especially concerning human beings. The concept of grammatical gender in Arabic is deeply rooted in its structure, influencing not only nouns and pronouns but also adjectives, verbs, and demonstratives. When pluralizing for people, the default gender often reverts to masculine in mixed-gender groups, a linguistic convention that is important for learners to grasp.
This rule is not merely a formality but dictates the correct form of adjectives, verbs, and even demonstrative pronouns that accompany these plurals.
1. The Masculine Default for Mixed Groups:
In Arabic, if a group consists of both males and females, even if there is only one male among many females, the Sound Masculine Plural (جمع المذكر السالم) is used. This is a crucial grammatical convention that might seem counter-intuitive from an English perspective but is fundamental to Arabic syntax. For instance, if you have a group of 99 female doctors and 1 male doctor, the entire group is referred to using the masculine plural أَطِبَّاءُ (aṭibbāʾ – doctors, a broken plural example) or if referring to professionals in general, مُوَظَّفُونَ (muwaẓẓafūn – employees, using Sound Masculine Plural).
This linguistic default is a key aspect of how Arabic constructs group identity.
2. Agreement with Adjectives and Verbs:
When a Sound Plural noun for people is used, any accompanying adjectives or verbs must agree with it in number and gender. This means if you are describing مُهَنْدِسُونَ (muhandisūn – engineers, masculine plural), the adjective must also be in the masculine plural form, and the verb conjugated for the masculine plural. Similarly, for مُعَلِّمَاتٌ (muʿallimāt – female teachers, feminine plural), adjectives and verbs will take the feminine plural form.
| Noun/Adjective Type | Singular Masculine | Plural Masculine (Nominative) | Singular Feminine | Plural Feminine (Nominative) |
|:---------------------|:----------------------------|:--------------------------------------|:--------------------------|:-------------------------------------|
| Active Participle | عَامِلٌ (ʿāmil – worker) | عَامِلُونَ (ʿāmilūna – workers) | عَامِلَةٌ (ʿāmilah – female worker) | عَامِلَاتٌ (ʿāmilātun – female workers) |
| Adjective | نَشِيطٌ (našīṭ – active) | نَشِيطُونَ (našīṭūna – active) | نَشِيطَةٌ (našīṭah – active) | نَشِيطَاتٌ (našīṭātun – active) |
Example of Agreement:
  • الْمُدَرِّسُونَ مُجْتَهِدُونَ. (Al-mudarrisūna mujtahidūna – The male teachers are diligent.) - Both noun and adjective are masculine plural.
  • الْمُدَرِّسَاتُ مُجْتَهِدَاتٌ. (Al-mudarrisātu mujtahidātun – The female teachers are diligent.) - Both noun and adjective are feminine plural.
  • يَعْمَلُ الْمُهَنْدِسُونَ فِي الْمَشْرُوعِ. (Yaʿmalu al-muhandisūna fī al-mašrūʿi – The engineers [male/mixed] work on the project.) - Verb يَعْمَلُ (yaʿmalu – he works) agrees with the masculine plural subject الْمُهَنْدِسُونَ.
This intricate system of agreement ensures grammatical cohesion within sentences and reinforces the importance of gender and number in Arabic. You will find that internalizing these agreement rules makes your Arabic sound more natural and grammatically correct.

When To Use It

The Sound Plurals are specifically reserved for rational beings – that is, humans. This is a fundamental distinction in Arabic grammar that you must always observe. You will primarily use these patterns when referring to professions, nationalities, or adjectives that describe people.
Their consistent application signals to the listener or reader that you are discussing sentient entities, adhering to a core principle of Arabic linguistic structure.
1. Professions and Occupations:
This is one of the most common applications. Any noun denoting a profession for an individual can typically be pluralized using the Sound Plural pattern, provided it refers to humans.
  • مُعَلِّم (muʿallim – male teacher) → مُعَلِّمُونَ (muʿallimūn – male teachers)
  • طَبِيبَة (ṭabībah – female doctor) → طَبِيبَات (ṭabībāt – female doctors)
  • مُوَظَّف (muwaẓẓaf – male employee) → مُوَظَّفُونَ (muwaẓẓafūn – male employees)
2. Nationalities:
When speaking about groups of people from a specific country, the Sound Plural is consistently employed.
  • مِصْرِيّ (miṣrī – Egyptian male) → مِصْرِيُّونَ (miṣriyyūn – Egyptians)
  • لُبْنَانِيَّة (lubnāniyyah – Lebanese female) → لُبْنَانِيَّات (lubnāniyyāt – Lebanese females)
  • أَلْمَانِيّ (almānī – German male) → أَلْمَانِيُّونَ (almāniyyūn – Germans)
3. Adjectives Describing People:
Any adjective used to describe human characteristics, traits, or states will take the Sound Plural form when referring to groups of people.
  • مُجْتَهِد (mujtahid – diligent male) → مُجْتَهِدُونَ (mujtahidūn – diligent males/people)
  • سَعِيدَة (saʿīdah – happy female) → سَعِيدَات (saʿīdāt – happy females)
  • مُبْدِع (mubdiʿ – creative male) → مُبْدِعُونَ (mubdiʿūn – creative males/people)
Key Usage Contexts:
  • Formal and Informal Communication: Whether writing an email, delivering a presentation, or chatting with friends, these plurals are the standard for discussing groups of people.
  • Official Documents: In professional settings and formal documents, precise application of Sound Plurals is expected.
  • Social Media: You will frequently see these plurals in captions, comments, and discussions when users refer to groups of individuals, reflecting modern usage.
It is imperative to remember that the Sound Plurals are exclusively for human beings. Applying them to non-human entities is a significant grammatical error that will be discussed further in the 'Common Mistakes' section. This strict differentiation is a hallmark of Arabic grammar and reinforces the language's logical structure.

Common Mistakes

Even experienced learners often stumble on specific aspects of Sound Plurals. Being aware of these common pitfalls and understanding the rationale behind them will significantly improve your accuracy and fluency. These mistakes often stem from trying to apply English pluralization rules or overlooking Arabic's specific gender and rationality distinctions.
1. Using Sound Plurals for Non-Human Entities:
This is arguably the most frequent and critical error. Sound Plurals are strictly for rational beings (humans). Non-human plurals, regardless of their gender in the singular, are treated grammatically as singular feminine (مُفْرَد مُؤَنَّث – mufrad muʾannath). This means any adjective describing a non-human plural will take the singular feminine form.
  • Incorrect: أَقْلاَمٌ جَمِيلُونَ. (Aqlāmun jamīlūna – Beautiful pens.) – أَقْلاَم (pens) is non-human, so جَمِيلُونَ (masculine plural) is wrong.
  • Correct: أَقْلاَمٌ جَمِيلَةٌ. (Aqlāmun jamīlah – Beautiful pens.) – جَمِيلَةٌ is singular feminine, correctly agreeing with the non-human plural أَقْلاَم.
  • Incorrect: سَيَّارَاتٌ سَرِيعَاتٌ. (Sayyārātun sarīʿātun – Fast cars.) – سَيَّارَات (cars) is non-human, so سَرِيعَاتٌ (feminine plural) is wrong.
  • Correct: سَيَّارَاتٌ سَرِيعَةٌ. (Sayyārātun sarīʿah – Fast cars.) – سَرِيعَةٌ is singular feminine.
2. Confusing Nominative (ـُونَ) with Accusative/Genitive (ـِينَ) for Masculine Plurals:
While A1 learners may not delve deep into grammatical cases, recognizing the difference between the -ūna and -īna endings is important for accurate sentence construction. Using the wrong case ending is a common mistake.
  • Incorrect: رَأَيْتُ الْمُعَلِّمُونَ. (Raʾaytu al-muʿallimūna – I saw the teachers.) – الْمُعَلِّمُونَ is nominative, but as the object of the verb رَأَيْتُ (I saw), it should be in the accusative case.
  • Correct: رَأَيْتُ الْمُعَلِّمِينَ. (Raʾaytu al-muʿallimīna – I saw the teachers.)
3. Forgetting to Remove ة (Tāʾ Marbūṭah) for Feminine Plurals:
When forming the Sound Feminine Plural, the ة (tāʾ marbūṭah) at the end of the singular noun must always be dropped before adding ـَات.
  • Incorrect: طَالِبَةَاتٌ. (Ṭālibatātun – Female students.) – The extra ة is incorrect.
  • Correct: طَالِبَاتٌ. (Ṭālibātun – Female students.)
4. Confusing Sound Plurals with Broken Plurals:
Many human nouns, especially common ones, take Broken Plurals. Learners sometimes incorrectly try to apply Sound Plural rules to these words.
  • Incorrect: رَجُلُونَ (Rajulūna – men.) – رَجُل (man) takes a Broken Plural.
  • Correct: رِجَالٌ (Rijālun – men.)
  • Incorrect: طِفْلُونَ (Ṭiflūna – children.) – طِفْل (child) takes a Broken Plural.
  • Correct: أَطْفَالٌ (Aṭfālun – children.)
There is no single rule to predict whether a human noun takes a Sound or Broken Plural; this requires memorization. However, adjectives and modern professions tend to follow the Sound Plural pattern more consistently.

Common Collocations

Collocations are words that frequently occur together, and understanding them helps in producing more natural and idiomatic Arabic. When learning Sound Plurals, focusing on common phrases and expressions where these plurals are used will enhance your communication skills and make your language sound more authentic.
Here are some common collocations involving Sound Plurals for people:
  • **For Sound Masculine Plural (ـُونَ / ـِينَ):
  • الْمُعَلِّمُونَ الْجُدُدُ (al-muʿallimūna al-jududu) – the new teachers (male/mixed). Often used in educational contexts, e.g., اسْتَقْبَلْنَا الْمُعَلِّمِينَ الْجُدُدَ. (Istaqbalnā al-muʿallimīna al-jududa – We welcomed the new teachers.)
  • الْمُهَنْدِسُونَ الْمَاهِرُونَ (al-muhandisūna al-māhirūna) – the skilled engineers. Frequently heard in professional and construction contexts, e.g., يَعْمَلُ الْمُهَنْدِسُونَ الْمَاهِرُونَ بِجِدٍّ. (Yaʿmalu al-muhandisūna al-māhirūna bi-jiddin – The skilled engineers work hard.)

Real Conversations

To truly master Sound Plurals, you must see and hear them in authentic, modern contexts. Arabic speakers naturally integrate these forms into daily interactions, from casual chats to formal communications. Observing their usage in social media, messaging apps, and spoken dialogue will help you internalize the patterns beyond textbook examples. The following scenarios demonstrate how these plurals appear in contemporary Arabic.

Quick FAQ

This section addresses common questions that A1 learners often have regarding the Sound Plurals for people. Understanding these nuances will solidify your grasp of this fundamental Arabic grammar rule.
  • Q1: Why is it called 'Sound Plural'?

It's called 'Sound' (سالم – sālim) because the singular form of the word remains intact and unchanged when the plural suffix is added. The original structure of the word is preserved, unlike Broken Plurals where the singular word undergoes internal changes.

  • Q2: Can I use ـُونَ or ـِينَ for a group of female individuals?

No. The ـُونَ and ـِينَ endings are exclusively for the Sound Masculine Plural, used for groups of men or mixed-gender groups. For groups composed solely of women, you must use the Sound Feminine Plural ending ـَات.

  • Q3: What if there's only one male in a group of 100 females? Which plural do I use?

According to standard Arabic grammatical convention, if there is even one male in a group, the entire group is grammatically referred to using the Sound Masculine Plural (or a Broken Plural that functions as masculine plural). This is a 'masculine default' rule in Arabic.

  • Q4: Do all words referring to humans use Sound Plurals?

No. While many professions, nationalities, and adjectives describing humans use Sound Plurals, some very common human nouns (e.g., رَجُل - rajul, man; اِمْرَأَة - imraʾah, woman; طِفْل - ṭifl, child) take Broken Plurals. These must be learned individually. Sound Plurals are more consistent for modern professions and adjectives.

  • Q5: What's the difference between ـُونَ and ـِينَ?

They both signify the Sound Masculine Plural, but their usage depends on the word's grammatical function (case) in the sentence. ـُونَ is used when the word is the subject (nominative case), while ـِينَ is used when the word is the object (accusative case) or follows a preposition or genitive construction (genitive case). For A1, recognizing both is important, even if full case application is learned later.

  • Q6: How do I pluralize non-human nouns like كِتَاب (book) or شَجَرَة (tree)?

Non-human nouns do not use Sound Plurals for people. Their plurals are often Broken Plurals (e.g., كُتُب for books, أَشْجَار for trees). Crucially, any adjective describing a non-human plural will always take the singular feminine form, regardless of the original noun's gender (e.g., كُتُبٌ كَبِيرَةٌ - kutubun kabīratun, large books; أَشْجَارٌ عَالِيَةٌ - ašjārun ʿāliyatun, tall trees).

  • Q7: Is مُهَنْدِس (engineer) an example of a root word for Sound Plurals?

Yes, مُهَنْدِس (muhandis) is derived from the root ه-ن-د-س and is a perfect example. It becomes مُهَنْدِسُونَ (male/mixed engineers) or مُهَنْدِسَاتٌ (female engineers). Many professions are derived from verb roots using specific patterns, and these often follow Sound Plural rules.
