Grammar Rule in 30 Seconds

Make masculine nouns plural by adding -oon or -een to the end of the singular word.

  • Add -oon (ون) for nominative case (subject): Mu'allim -> Mu'allimoon (Teachers).
  • Add -een (ين) for accusative/genitive case (object/after preposition): Mu'allimeen (Teachers).
  • Only use this for specific masculine human nouns, usually professions or adjectives.
Singular Noun + (ون / ين) = Plural Noun

Overview

Arabic noun plurals present a unique linguistic system, diverging significantly from the relatively straightforward suffixation found in English. Among the various plural formations, the Sound Masculine Plural (الجمع المذكر السالم - al-jam' al-mudhakkar as-sālim) stands out for its regularity and predictability. Its name, "sound," directly refers to the singular form remaining unbroken or undistorted when pluralized; you simply append a specific suffix.

This contrasts sharply with the Broken Plural (جمع التكسير - jam' at-taksīr), where the internal structure of the word changes (e.g., kitāb / كتاب - book → kutub / كتب - books). The Sound Masculine Plural is primarily, though not exclusively, used for rational masculine beings – individuals, professions, and nationalities. Understanding this pattern is fundamental for A1 learners, as it provides a stable foundation for pluralizing a significant category of nouns and adjectives that refer to people.

It represents one of the two main "sound" plural patterns, the other being the Sound Feminine Plural (al-jam' al-mu'annath as-sālim). Its existence highlights Arabic's meticulous approach to grammatical agreement and meaning, ensuring clarity when discussing groups of people.

How This Grammar Works

The core mechanism of the Sound Masculine Plural is suffixation modulated by grammatical case. Unlike English, Arabic nouns change their endings not only for number (singular, dual, plural) and gender, but also to indicate their grammatical function within a sentence (subject, object, possessor, etc.). This is known as declension.
For the Sound Masculine Plural, there are two primary suffixes, each tied to a specific case:
  • Nominative Case (الرفع - ar-raf'): This case is used for the subject of a verb, the predicate of a nominal sentence, or the noun after inna and its sisters. The suffix for the Sound Masculine Plural in the nominative case is -ūna (ـُونَ). For example, al-mu'allimūna (المعلِّمُونَ - the teachers) if they are the ones performing an action.
  • Accusative Case (النصب - an-nasb) and Genitive Case (الجر - al-jarr): These two cases share the same suffix for the Sound Masculine Plural. The accusative case is typically used for the direct object of a verb or the object after kāna and its sisters. The genitive case is used for the object of a preposition or the second term in an iḍāfa (possessive construction). The suffix for both the accusative and genitive cases is -īna (ـِينَ). For instance, al-mu'allimīna (المعلِّمِينَ - the teachers) if they are being acted upon or are preceded by a preposition.
This case-sensitive ending is a crucial aspect of Arabic grammar that beginners must grasp, as using the incorrect suffix changes the grammatical role of the plural noun and can lead to misunderstandings. The underlying principle is the preservation of the singular stem, mu'allim (معلِّم), to which these endings are simply attached. The final nūn (ن) of the suffix often drops in iḍāfa constructions, but this is an advanced nuance (see Common Mistakes).

Formation Pattern

1
Forming the Sound Masculine Plural is a systematic process that involves taking a singular masculine noun or adjective and appending the appropriate suffix, contingent upon its grammatical function (case) in the sentence. The singular form itself undergoes no internal changes, preserving its original harakāt (vowel markings) until the suffix is added.
2
Step-by-Step Formation:
3
Identify a Suitable Singular Noun/Adjective: The word must be a masculine noun or adjective referring to a rational being (person), and it should not end in tā' marbūṭa (ة), as that typically indicates femininity and would require a different plural pattern (Sound Feminine Plural).
4
Example: muhandis (مهندس - engineer)
5
Example: nājah (ناجح - successful, as an adjective)
6
Determine the Grammatical Case: Decide whether the noun/adjective will function in the nominative, accusative, or genitive case within your sentence.
7
Append the Correct Suffix: Add either -ūna (ـُونَ) for nominative or -īna (ـِينَ) for accusative/genitive.
8
Formation Table:
9
| Singular (Masculine) | Meaning | Nominative Plural (-ūna) | Accusative/Genitive Plural (-īna) |
10
| :------------------- | :------------ | :----------------------- | :-------------------------------- |
11
| muhandis (مهندس) | engineer | muhandisūna (مهندسُونَ) | muhandisīna (مهندسِينَ) |
12
| mu'allim (معلِّم) | teacher | mu'allimūna (معلِّمُونَ) | mu'allimīna (معلِّمِينَ) |
13
| kātib (كاتب) | writer | kātibūna (كاتبُونَ) | kātibīna (كاتبِينَ) |
14
| muslim (مسلم) | Muslim | muslimūna (مسلمُونَ) | muslimīna (مسلمينَ) |
15
| mutarjim (مترجم) | translator | mutarjimūna (مترجمُونَ) | mutarjimīna (مترجمِينَ) |
16
| ṣādiq (صادق) | truthful (adj)| ṣādiqūna (صادقُونَ) | ṣādiqīna (صادقِينَ) |
17
Notice that the singular form remains perfectly intact. The only change is the addition of the suffix. For example, المعلِّمُ (the teacher) becomes المعلِّمُونَ (the teachers, subject) or المعلِّمِينَ (the teachers, object/possessive). This consistency is why it's called "sound" or "whole." The damma on the lām of mu'allim is replaced by the wāw in the nominative plural, and the kasra on the lām is replaced by the yā' in the accusative/genitive. The nūn always carries a fatḥa (نَ).

Gender & Agreement

The Sound Masculine Plural, despite its name, serves as the default plural for groups of people that are either exclusively male or are of mixed gender. In Arabic grammar, the masculine plural overrides the feminine plural when both genders are present. This means that even a group consisting of ninety-nine women and one man will grammatically be referred to using the Sound Masculine Plural.
Agreement with Adjectives:
When an adjective modifies a noun in the Sound Masculine Plural, the adjective itself must also take the Sound Masculine Plural form and agree in case. This is a fundamental rule of noun-adjective agreement in Arabic.
  • Example (Nominative): المهندسونَ الماهرونَ (al-muhandisūna al-māhirūna - the skilled engineers). Here, both muhandisūna (engineers) and māhirūna (skilled) are in the nominative plural form.
  • Example (Accusative/Genitive): رأيتُ المعلمينَ النشيطينَ (ra'aytu al-mu'allimīna an-našīṭīna - I saw the active teachers). Both al-mu'allimīna (teachers) and an-našīṭīna (active) are in the accusative plural form, as they are direct objects.
The Overriding Masculine:
This grammatical convention of masculine overriding feminine in mixed groups is a fixed feature of Modern Standard Arabic (MSA) and reflects a historical linguistic pattern. While some modern spoken dialects might adapt to refer to the majority gender (e.g., using a feminine plural if a group is overwhelmingly female), in formal MSA, the Sound Masculine Plural remains the correct choice for any group that includes at least one male.
  • Consider a team of doctors: if it's all men, it's الأطبّاءُ (broken plural for doctors, but conceptually masculine). If it's all women, it's الطبيباتُ (aṭ-ṭabībātu - Sound Feminine Plural). If it's men and women, the default for an adjective referring to the group would revert to a masculine plural, or a singular noun referring to the group might take a broken plural like الأطبّاءُ (for 'doctors' in general, often used for mixed groups).
This rule emphasizes that the "masculine" in Sound Masculine Plural refers to its grammatical behavior rather than necessarily a purely male demographic.

When To Use It

The Sound Masculine Plural is not a universal pluralizer; its application is specific and governed by the characteristics of the noun or adjective. It is primarily reserved for rational beings and specific types of words, making it a powerful and efficient pattern when correctly applied.
1. Rational Beings (Humans):
This is the most crucial condition. The Sound Masculine Plural is almost exclusively used for people – individuals, their professions, nationalities, or qualities. It is not used for inanimate objects, animals, or abstract concepts, even if they are grammatically masculine in the singular.
  • Professions: مُحَاسِب (muḥāsib - accountant) → مُحَاسِبُونَ (muḥāsibūna)
  • Nationalities: مِصْرِيّ (miṣrī - Egyptian) → مِصْرِيُّونَ (miṣriyyūna)
  • Participants/Doers (Active Participles): Words that describe someone performing an action, often derived from verbs (fā'il pattern).
  • كَاتِب (kātib - writer, lit. 'one who writes') → كَاتِبُونَ (kātibūna)
  • سَائِح (sā'iḥ - tourist, lit. 'one who travels') → سَائِحُونَ (sā'iḥūna)
  • Qualities/Adjectives of People: Adjectives describing human traits.
  • صَادِق (ṣādiq - truthful) → صَادِقُونَ (ṣādiqūna)
  • مُجْتَهِد (mujtahid - diligent) → مُجْتَهِدُونَ (mujtahidūna)
2. Masculine or Mixed Groups:
As discussed, this plural form is used for groups composed entirely of men or groups that include both men and women. The grammatical masculine takes precedence.
3. Absence of tā' marbūṭa (ة):
The singular form must not end in a tā' marbūṭa (ة). If it does, and refers to a female rational being, it will likely take the Sound Feminine Plural (-āt).
  • مُعَلِّمَة (mu'allimah - female teacher) → مُعَلِّمَات (mu'allimāt)
4. Select Proper Nouns:
Some proper nouns referring to groups or categories of people can also take this plural, such as the names of tribes or groups of followers.
It is important to remember that not all masculine rational nouns form their plural in this way. Many common nouns, like رَجُل (rajul - man) which becomes رِجَال (rijāl - men), use the Broken Plural. Therefore, while the Sound Masculine Plural is predictable if a word follows this pattern, discerning which words follow it requires exposure and, at early stages, often memorization or dictionary consultation.

Common Mistakes

Learners frequently encounter specific challenges when applying the Sound Masculine Plural. These errors often stem from overgeneralization, confusion with other plural types, or a lack of attention to grammatical case.
1. Overapplying to Non-Rational Nouns:
The most common mistake is attempting to use the -ūna/-īna suffixes for inanimate objects or animals, simply because they are masculine in the singular. Remember: this plural is almost exclusively for people.
Incorrect
✗Incorrect: كِتَاب (kitāb - book)
✓كِتَابُونَ (kitābūna) X
✗Correct: كِتَاب (kitāb)
✓كُتُب (kutub - books) ✓ (Broken Plural)
2. Confusing with Broken Plurals:
Many masculine nouns referring to rational beings take a Broken Plural, not the Sound Masculine. Learners often try to apply -ūna/-īna to these words.
✗Incorrect: طَالِب (ṭālib - student)
✓طَالِبُونَ (ṭālibūna) X
✗Correct: طَالِب (ṭālib)
✓طُلَّاب (ṭullāb - students) ✓ (Broken Plural)
✗Incorrect: صَدِيق (ṣadīq - friend)
✓صَدِيقُونَ (ṣadīqūna) X
✗Correct: صَدِيق (ṣadīq)
✓أَصْدِقَاء (aṣdiqā' - friends) ✓ (Broken Plural)
There isn't a simple rule to predict whether a rational noun takes a Sound or Broken Plural; it often depends on the word's etymology and common usage. Active participles (words describing a doer, often derived from a verb, like كاتب - writer) are very likely to take the Sound Masculine Plural.
3. Incorrect Case Usage:
Mixing up -ūna and -īna is a significant error, as it fundamentally alters the noun's grammatical function.
  • Context: "The teachers (مُعَلِّمُونَ) arrived." (Subject = Nominative)
  • Incorrect: وَصَلَ المُعَلِّمِينَ (waṣala al-mu'allimīna) X
  • Correct: وَصَلَ المُعَلِّمُونَ (waṣala al-mu'allimūna) ✓
  • Context: "I saw the teachers (مُعَلِّمِينَ)." (Object = Accusative)
  • Incorrect: رَأَيْتُ المُعَلِّمُونَ (ra'aytu al-mu'allimūna) X
  • Correct: رَأَيْتُ المُعَلِّمِينَ (ra'aytu al-mu'allimīna) ✓
4. Dropping the nūn Incorrectly:
The final nūn (ن) of the -ūna/-īna suffix drops when the plural noun is the first term in an iḍāfa (possessive construction). This is a common point of confusion.
  • Incorrect: مُعَلِّمُونَ الفَصْلِ (mu'allimūna al-faṣli) X (The teachers of the class)
  • Correct: مُعَلِّمُو الفَصْلِ (mu'allimū al-faṣli) ✓
5. Dialectal Overgeneralization:
In many spoken Arabic dialects, the -īn ending is used for all cases of the Sound Masculine Plural, effectively neutralizing the case distinction. While this is natural in informal speech, it is incorrect in Modern Standard Arabic. A learner transitioning from dialect exposure to MSA might incorrectly apply the -īn ending universally in formal contexts.
Understanding these common pitfalls will help learners navigate the complexities of Arabic plurals more effectively and produce grammatically accurate sentences.

Common Collocations

The Sound Masculine Plural appears frequently in various contexts, particularly when discussing groups of professionals, nationalities, or people engaged in specific activities. Recognizing these common collocations can accelerate vocabulary acquisition and practical application.
1. Professions and Roles:
Many job titles and roles naturally form this plural, especially those derived from active participles (fā'il or mu-fā'il patterns).
  • المُدَرِّسُونَ الجُدُدُ (al-mudarrisūna al-jududu - the new male teachers)
  • المُهَنْدِسُونَ فِي الشَّرِكَةِ (al-muhandisūna fī ash-sharika - the engineers in the company)
  • المُصَوِّرُونَ الْمُبْدِعُونَ (al-muṣawwirūna al-mubdi'ūna - the creative photographers)
2. Nationalities and Affiliations:
Words indicating origin or affiliation often use this plural.
  • السُّعُودِيُّونَ وَالْمَصْرِيُّونَ (as-su'ūdiyyūna wal-maṣriyyūna - the Saudis and the Egyptians)
  • المُسْلِمُونَ فِي أُورُوبَا (al-muslimūna fī ūrūbā - the Muslims in Europe)
3. Groups with Shared Qualities/Actions:
Adjectives describing groups of people also frequently collocate with nouns or implied nouns in this plural form.
  • الفَائِزُونَ بِالْجَائِزَةِ (al-fā'izūna bil-jā'iza - the winners of the prize)
  • الشَّاكِرُونَ للهِ (ash-shākirūna lillāhi - those grateful to God)
  • السَّاعُونَ إِلَى الْخَيْرِ (as-sā'ūna ilā al-khayri - those striving for good)
4. Modern Contexts:
In contemporary Arabic, especially in media and online discourse, this plural is used for groups in various modern fields.
  • المُبَرْمِجُونَ (al-mubarmījūna - the programmers)
  • المُطَوِّرُونَ (al-muṭawwirūna - the developers)
  • المُتَابِعُونَ (al-mutābi'ūna - the followers, e.g., on social media)
These collocations demonstrate the natural flow of the Sound Masculine Plural in Arabic. Pay attention to how these words are used in news articles, social media, and academic texts to internalize their usage patterns.

Real Conversations

While Modern Standard Arabic (MSA) meticulously observes the case distinctions (-ūna vs. -īna), everyday spoken Arabic dialects (العامية - al-'āmmiyyah) often simplify this. A key characteristic in many, though not all, dialects (like Egyptian, Levantine, and Gulf) is the near-universal use of the -īn ending, regardless of grammatical case. This is a crucial difference for learners to note.

MSA Example (Formal Dialogue):

A

Ahmed

مَنْ هَؤُلَاءِ الرِّجَالُ؟ (man hā'ulā'i ar-rijālu? - Who are these men?)
F

Fatima

هُمُ الْمُعَلِّمُونَ الْجُدُدُ فِي الْمَدْرَسَةِ. (humu al-mu'allimūna al-jududu fī al-madrasa. - They are the new teachers in the school.)

(Here, al-mu'allimūna is the predicate of a nominal sentence, hence nominative (-ūna).)*

A

Ahmed

هَلْ رَأَيْتِ الْمُهَنْدِسِينَ فِي الِاجْتِمَاعِ؟ (hal ra'ayti al-muhandisīna fī al-ijtima'i? - Did you see the engineers in the meeting?)
F

Fatima

نَعَمْ، تَكَلَّمْتُ مَعَ الْمُهَنْدِسِينَ عَنِ الْمَشْرُوعِ. (na'am, takallamtu ma'a al-muhandisīna 'ani al-mashrū'. - Yes, I spoke with the engineers about the project.)

(Here, al-muhandisīna is the direct object in the first question and object of preposition ma'a (with) in the second, hence accusative/genitive (-īna).)*

Dialectal Example (Egyptian Arabic - Informal):

A

Ahmed

مين دول الرجالة؟ (mīn dūl ir-rijāla? - Who are these men?)
F

Fatima

دول المدرسين الجداد في المدرسة. (dūl il-mudarrisīn il-gidād fil-madrasa. - They are the new teachers in the school.)

(Notice il-mudarrisīn is used even though it's technically in a nominative position.)*

A

Ahmed

شوفت المهندسين في الاجتماع؟ (shuft il-muhandisīn fil-igtimā'? - Did you see the engineers in the meeting?)
F

Fatima

آه، اتكلمت مع المهندسين عن المشروع. (āh, itkallimt ma'a il-muhandisīn 'an il-mashrū'. - Yes, I spoke with the engineers about the project.)

(Here, il-muhandisīn is used consistently for both object and after preposition.)*

T

This distinction is vital

while the -īn form is practically ubiquitous in spoken Arabic for this plural, MSA retains the -ūna for nominative contexts. For A1 learners, mastering the MSA rules (-ūna for subject, -īna for object/after preposition) is paramount, as it forms the basis for formal communication, reading, and writing. Awareness of dialectal simplification should come once the MSA foundation is solid, to avoid confusing formal and informal registers.

Quick FAQ

  • Q: How do I know if a noun takes the Sound Masculine Plural or a Broken Plural?
A: The most reliable indicator is if the noun is an active participle (اسم الفاعل - ism al-fā'il), often following patterns like فَاعِل (fā'il) or مُفَعِّل (mufa''il), and refers to a person. Examples include كاتب (writer), معلم (teacher), مهندس (engineer). Basic, common nouns like رجل (man) or ولد (boy) almost always take Broken Plurals.
For less common words, consulting a dictionary or usage examples is essential. Over time, you will develop an intuition for which pattern a word is likely to follow.
  • Q: Can I use this plural for a group of 99 women and 1 man?
A: Yes, grammatically. In Modern Standard Arabic, the masculine plural form (-ūna/-īna) is used for any group containing at least one male, regardless of the numerical majority of women. The masculine gender grammatically overrides the feminine in such mixed contexts.
While conversational Arabic might sometimes adapt for emphasis, formal Arabic adheres strictly to this rule.
  • Q: Why are there two endings (-ūna and -īna)?
A: These two endings indicate the noun's grammatical case within the sentence. -ūna is used when the noun is in the nominative case (e.g., the subject of a verb). -īna is used when the noun is in the accusative case (e.g., the direct object) or the genitive case (e.g., after a preposition or in a possessive construction).
This distinction is crucial for conveying the precise grammatical role of the plural noun in MSA.
  • Q: Does this rule apply to all adjectives?
A: It applies to masculine adjectives that describe rational beings (people) when those adjectives are used to modify a Sound Masculine Plural noun. The adjective must agree in gender, number, and case with the noun it describes. For instance, المعلمونَ النشيطونَ (the active teachers) correctly shows النشيطونَ (active, plural, nominative) agreeing with المعلمونَ (teachers, plural, nominative).
  • Q: What about the nūn at the end of the suffix? Does it ever change or drop?
A: The nūn (ن) always has a fatḥa (نَ) in the Sound Masculine Plural endings (-ūna / ـُونَ and -īna / ـينَ). However, this nūn drops when the Sound Masculine Plural noun is the first term in an iḍāfa construction (a possessive phrase, like "teachers of the school"). For example, مُعَلِّمُو الْمَدْرَسَةِ (mu'allimū al-madrasati - the teachers of the school), where the nūn of mu'allimūna is removed.
This is a regular feature of Arabic grammar for iḍāfa.
  • Q: Is there a similar "sound" plural for feminine nouns?
A: Yes, there is the Sound Feminine Plural (الجمع المؤنث السالم - al-jam' al-mu'annath as-sālim), which is formed by adding the suffix -āt (ـَات) to the singular feminine noun, typically replacing the tā' marbūṭa (ة). For example, معلمة (female teacher) becomes معلمات (female teachers). It also has specific case markings, but its formation is simpler.
This pattern is primarily for feminine rational and sometimes inanimate nouns.

In spoken dialects, the -oon and -een endings often collapse into just -een for both cases.

Similar to Levantine, -een is very common in speech.

More likely to maintain the MSA distinction in formal settings.

This suffix system evolved from the Proto-Semitic case endings.
