Grammar Rule in 30 Seconds

To make most masculine human nouns plural, just add 'ūn' or 'īn' to the end of the singular word.

  • Add 'ūn' (ـون) for nominative case (subject): مُعَلِّم -> مُعَلِّمُون (Teachers)
  • Add 'īn' (ـين) for accusative/genitive cases (object/after preposition): مُعَلِّم -> مُعَلِّمِين (Teachers)
  • This rule applies primarily to human masculine nouns, specifically those describing professions or attributes.
Singular Noun + (ūn/īn) = Plural Group

Overview

Arabic, a language of profound structure and precision, employs specific patterns to indicate plurality. Among these, the Sound Masculine Plural (جَمْعُ الْمُذَكَّرِ السَّالِمُ, jam' al-mudhakkar as-sālim) stands out for its clarity and predictability. This pattern is primarily used for forming the plural of masculine nouns and adjectives that refer to rational beings – specifically, humans.

The term "sound" (سَالِمُ) is key: it signifies that the original singular word's structure remains intact, without any internal changes, making it one of the most straightforward plural formations in Arabic grammar. Unlike many other Arabic plurals, which often involve breaking the singular word's internal vowel patterns (كِتَابٌ becomes كُتُبٌ), the Sound Masculine Plural simply adds a suffix to the end.

This pattern allows you to systematically pluralize words like مُهَنْدِسٌ (engineer) to مُهَنْدِسُونَ (engineers) or مُعَلِّمٌ (teacher) to مُعَلِّمُونَ (teachers) by attaching one of two distinct endings. This consistency makes it invaluable for beginners, as it removes much of the memorization burden associated with irregular "broken" plurals. It functions much like adding '-s' or '-es' in English, but with an added layer of grammatical case marking that signals the word's role in a sentence.

How This Grammar Works

In Arabic, the function of a noun or adjective within a sentence dictates its grammatical case. For the Sound Masculine Plural, this means choosing between two distinct endings: ـُونَ (-ūna) or ـِينَ (-īna). This distinction is crucial for conveying meaning accurately and is a fundamental aspect of Modern Standard Arabic (MSA).
  1. 1**The Nominative Case (حَالَةُ الرَّفْعِ - ḥālat ar-raf'i) with ـُونَ (-ūna):
You use the ـُونَ ending when the plural noun or adjective is in the nominative case. This typically occurs when the word is the subject of a sentence – the one performing the action. It's akin to using "he" or "they" in English.
For instance, if you want to say "The teachers arrived," you'd use the ـُونَ ending for "teachers."
  • جَاءَ الْمُعَلِّمُونَ. (jā’a al-mu'allimūna.) – The teachers arrived. (الْمُعَلِّمُونَ is the subject.)
  • الْمُسْلِمُونَ صَادِقُونَ. (al-muslimūna ṣādiqūna.) – The Muslims are truthful. (الْمُسْلِمُونَ is the subject, صَادِقُونَ is the predicate adjective.)
  1. 1**The Accusative/Genitive Case (حَالَةُ النَّصْبِ وَالْجَرِّ - ḥālat an-naṣbi wa al-jarri) with ـِينَ (-īna):
The ـِينَ ending is employed when the plural noun or adjective is in either the accusative or the genitive case. This means the word is typically the object of a verb (receiving the action) or follows a preposition. This is comparable to using "him" or "them" in English.
  • رَأَيْتُ الْمُهَنْدِسِينَ. (ra'aytu al-muhandisīna.) – I saw the engineers. (الْمُهَنْدِسِينَ is the object of the verb "saw.")
  • سَلَّمْتُ عَلَى الْمُسَافِرِينَ. (sallamtu 'alā al-musāfirīna.) – I greeted the travelers. (الْمُسَافِرِينَ follows the preposition عَلَى.)
  • نَحْتَرِمُ الْمُوَظَّفِينَ. (naḥtarimu al-muwaẓẓafīna.) – We respect the employees. (الْمُوَظَّفِينَ is the object of the verb "respect.")
The final نُونٌ (nūn) – the letter ن at the end of both ـُونَ and ـِينَ – is a critical component of these suffixes. It marks the plurality and is always pronounced, except in specific advanced grammatical constructions (known as إِضَافَةٌ - iḍāfah), which you will learn later. For now, always keep the نُونٌ.

Formation Pattern

1
Forming the Sound Masculine Plural is a straightforward process. You simply take the singular masculine noun or adjective (referring to a human) and append the appropriate suffix. This pattern relies on the singular form remaining unchanged, which is why it's considered "sound."
2
Here's the step-by-step process:
3
Identify a Singular Masculine Noun or Adjective: The word must be masculine and refer to a human or a human quality. Examples include مُدَرِّسٌ (teacher), مُهَنْدِسٌ (engineer), فَلَّاحٌ (farmer), صَادِقٌ (truthful - adjective).
4
Remove the تَاءُ الْمَرْبُوطَةِ (tā’ al-marbūṭah) if Present: If the word ends with ـَةٌ (which would make it feminine), this pattern is not applicable. The Sound Masculine Plural is exclusively for masculine forms. For instance, مُدَرِّسَةٌ (female teacher) would not use this plural; it uses the Sound Feminine Plural (مُدَرِّسَاتٌ).
5
Append the Correct Suffix:
6
For the Nominative Case (Subject): Add ـُونَ (-ūna) to the end of the singular word.
7
For the Accusative/Genitive Case (Object/Preposition): Add ـِينَ (-īna) to the end of the singular word.
8
Consider the word مُسْلِمٌ (Muslim):
9
Singular: مُسْلِمٌ (muslimun)
10
Nominative Plural: مُسْلِمُونَ (muslimūna)
11
Accusative/Genitive Plural: مُسْلِمِينَ (muslimīna)
12
Let's look at a table for clarity:
13
| Singular (Nominative) | Sound Masculine Plural (Nominative) | Sound Masculine Plural (Accusative/Genitive) |
14
| :-------------------- | :---------------------------------- | :------------------------------------------- |
15
| مُدَرِّسٌ (teacher) | مُدَرِّسُونَ (mudarrisūna) | مُدَرِّسِينَ (mudarrisīna) |
16
| مُهَنْدِسٌ (engineer)| مُهَنْدِسُونَ (muhandisūna) | مُهَنْدِسِينَ (muhandisīna) |
17
| صَحَفِيٌّ (journalist)| صَحَفِيُّونَ (ṣaḥafiyyūna) | صَحَفِيِّينَ (ṣaḥafiyyīna) |
18
| صَابِرٌ (patient) | صَابِرُونَ (ṣābirūna) | صَابِرِينَ (ṣābirīna) |
19
Notice how the last letter of the singular word (e.g., س in مُدَرِّسٌ) connects directly to the و (wāw) of ـُونَ or the ي (yā’) of ـِينَ. The vocalization of the preceding consonant is usually a ḍamma (u) for ـُونَ and a kasra (i) for ـِينَ (e.g., مُدَرِّسُونَ, مُدَرِّسِينَ).

Gender & Agreement

The Sound Masculine Plural plays a specific role in Arabic's gendered grammar system. It is strictly for masculine nouns and adjectives. However, a crucial rule for learners is its application to mixed-gender groups.
  • Masculine Specificity: This plural is used when referring to a group composed entirely of men, or a group of masculine concepts that are rational beings (like specific job titles).
  • الْعَامِلُونَ فِي الْمَصْنَعِ. (al-'āmilūna fī al-maṣna'i.) – The workers in the factory (assuming all male workers or a mixed group).
  • Mixed-Gender Groups: In Arabic, grammatical gender defaults to masculine when a group contains both males and females. If you have a group of ten women and one man, the entire group is pluralized using the masculine plural. This is a fundamental linguistic convention, not a social statement.
  • If you have five female students (طَالِبَاتٌ) and one male student (طَالِبٌ) in a class, the entire group would be referred to as الطُّلَّابُ (the students, using a broken plural for طَالِبٌ), or if applicable, using the Sound Masculine Plural for a word that takes it.
  • Consider a board of directors with female and male members: you would refer to them as أَعْضَاءُ مَجْلِسِ الإِدَارَةِ (members of the board of directors), where أَعْضَاءُ is the broken plural of عُضْوٌ (member), which functions as a masculine plural for the mixed group.
  • For words that readily take the sound masculine plural, like مُدِيرٌ (manager), if a group includes both مُدِيرَاتٌ (female managers) and مُدِيرُونَ (male managers), you would generalize to الْمُدِيرُونَ.
  • Adjective Agreement: Adjectives modifying a Sound Masculine Plural noun must also take the Sound Masculine Plural form and agree in case. This ensures clarity and grammatical cohesion.
  • رَأَيْتُ الْمُعَلِّمِينَ الْمُجْتَهِدِينَ. (ra'aytu al-mu'allimīna al-mujtahidīna.) – I saw the hardworking teachers. (الْمُعَلِّمِينَ is accusative, so الْمُجْتَهِدِينَ is also accusative.)
  • الْمُوَظَّفُونَ الْجُدُدُ وَصَلُوا. (al-muwaẓẓafūna al-jududu waṣalū.) – The new employees arrived. (الْمُوَظَّفُونَ is nominative, so الْجُدُدُ (the adjective for new, here functioning like a plural adjective, although 'جديد' itself often takes 'جدد' as a broken plural for humans) must agree in case. A more direct example would be الْمُعَلِّمُونَ النَّاجِحُونَ (the successful teachers).)
Understanding this agreement is fundamental to constructing grammatically correct and natural-sounding Arabic sentences, particularly when describing groups of people.

When To Use It

The Sound Masculine Plural is widely used across various contexts in Arabic, especially when discussing groups of people and their roles. Its application extends from formal communication to everyday interactions and even digital platforms.
  • Professions and Occupations: This is one of the most common applications. Any job title referring to men will typically form its plural this way, provided it doesn't have an established broken plural.
  • نَحْنُ نَبْحَثُ عَنْ مُبَرْمِجِينَ مَاِهرِينَ. (naḥnu nabḥathu 'an mubarmigīna māhirīna.) – We are looking for skilled programmers. (Accusative case for مُبَرْمِجِينَ).
  • الْمُحَاسِبُونَ فِي الشَّرِكَةِ مُجْتَهِدُونَ. (al-muḥāsibūna fī ash-sharikaati mujtahidūna.) – The accountants in the company are hardworking. (Nominative case for الْمُحَاسِبُونَ).
  • Nationalities: Many nationalities, particularly those ending in ـِيٌّ (-iyy), use this pattern.
  • الْمِصْرِيُّونَ مُحِبُّونَ لِوَطَنِهِم. (al-miṣriyyūna muḥibbūna li-waṭanihim.) – The Egyptians love their homeland. (الْمِصْرِيُّونَ is nominative).
  • الْتَقَيْتُ بِسُعُودِيِّينَ فِي دُبَي. (iltaqaytu bi-su'ūdiyyīna fī dubai.) – I met Saudis in Dubai. (Genitive case after بِـ).
  • Adjectives Describing People: When you want to describe a group of people with a particular quality, the adjective will often take the Sound Masculine Plural.
  • الْمُؤْمِنُونَ الصَّادِقُونَ هُمْ أَهْلُ الْجَنَّةِ. (al-mu'minūna aṣ-ṣādiqūna hum ahlu al-jannati.) – The truthful believers are the people of Paradise. (Both are nominative, a common phrase in religious texts).
  • شَاهَدْتُ الطُّلَّابَ الْمُتَفَوِّقِينَ. (shāhadtu aṭ-ṭullāba al-mutafawwiqīna.) – I watched the excelling students. (Here, الطُّلَّابَ is a broken plural, but the adjective الْمُتَفَوِّقِينَ takes the sound masculine plural form to agree).
  • Modern Digital Contexts: In today's digital landscape, this plural is frequently encountered.
  • On social media, terms like مُتَابِعُونَ (followers) or مُشَاهِدُونَ (viewers) will use this pattern, adjusting their endings based on context. For example, a post might say شُكْرًا لِمُتَابِعِينَنا الْكِرَامِ (Thanks to our esteemed followers), where مُتَابِعِينَ is genitive.
  • In professional networking like LinkedIn, job titles for teams or departments often leverage this structure (e.g., مُطَوِّرُونَ for developers).
Essentially, whenever you need to refer to a group of three or more human males, or a mixed-gender group, and the singular noun or adjective allows for this regular pluralization, the Sound Masculine Plural is your go-to pattern.

Common Mistakes

While the Sound Masculine Plural is predictable, learners frequently make specific errors. Awareness of these pitfalls can significantly improve your accuracy and fluency.
  • Confusing ـُونَ and ـِينَ: This is the most prevalent mistake. Incorrectly using the nominative suffix in an accusative or genitive context, or vice versa, is a clear grammatical error. It’s similar to saying "Them went to the store" instead of "They went to the store."
  • Incorrect: رَأَيْتُ الْمُعَلِّمُونَ. (Should be رَأَيْتُ الْمُعَلِّمِينَ.) – I saw the teachers.
  • Incorrect: جَاءَ الْمُهَنْدِسِينَ. (Should be جَاءَ الْمُهَنْدِسُونَ.) – The engineers came.
This error indicates a lack of understanding of grammatical case, a core concept in Arabic.
  • Using for Non-Rational Nouns: A common misconception is to apply this plural to any masculine noun, regardless of whether it refers to a human. The Sound Masculine Plural is reserved for rational beings. Non-human masculine nouns use broken plurals or, less commonly, the Sound Feminine Plural (ـَاتٌ) if they are semantically treated as such.
  • Incorrect: قَلَمُونَ for "pens" (singular قَلَمٌ). The correct broken plural is أَقْلَامٌ.
  • Incorrect: بَيْتُونَ for "houses" (singular بَيْتٌ). The correct broken plural is بُيُوتٌ.
This mistake can lead to very unnatural or even nonsensical expressions to a native speaker.
  • Using for Feminine Nouns: Always remember the "Masculine" in Sound Masculine Plural. It cannot be used for nouns that are grammatically feminine.
  • Incorrect: طَالِبَاتُونَ for female students (singular طَالِبَةٌ). The correct plural is طَالِبَاتٌ (Sound Feminine Plural).
  • Incorrect: سَيَّارُونَ for cars (singular سَيَّارَةٌ). The correct plural is سَيَّارَاتٌ.
  • Dropping the نُونُ الْجَمْعِ Prematurely: The final نُونٌ of ـُونَ or ـِينَ is typically dropped only when the word is in an إِضَافَةٌ (genitive construction) – a more advanced topic where a noun is possessed by another noun (e.g., مُهَنْدِسُو الشَّرِكَةِ - the engineers of the company, not مُهَنْدِسُونَ الشَّرِكَةِ). For A1 learners, it's best to always retain the نُونٌ.
  • Over-Applying to Nouns with Broken Plurals: Not all masculine human nouns use the Sound Masculine Plural. Many common nouns referring to people have irregular broken plurals that must be memorized. Trying to force the sound masculine plural on them is incorrect.
  • وَلَدٌ (boy) becomes أَوْلَادٌ (not وَلَدُونَ).
  • رَجُلٌ (man) becomes رِجَالٌ (not رَجُلُونَ).
  • طَالِبٌ (male student) becomes طُلَّابٌ (not طَالِبُونَ), though طَالِبٌ can sometimes take the sound masculine plural, طَالِبُونَ, especially in a more modern context or as an adjective. However, طُلَّابٌ is far more common for students in general.
The best approach is to learn the plural form alongside the singular for each new noun.

Common Collocations

Understanding common collocations – words that naturally go together – helps embed the Sound Masculine Plural into your active vocabulary. These phrases illustrate how the plural functions in typical Arabic expressions.
  • الْمُوَظَّفُونَ الْجُدُدُ (al-muwaẓẓafūna al-jududu) – The new employees. (Nominative. مُوَظَّفٌ - employee, جَدِيدٌ - new).
  • الْمُدَرِّسُونَ الْمَاهِرُونَ (al-mudarrisūna al-māhirūna) – The skilled teachers. (Nominative. مُدَرِّسٌ - teacher, مَاهِرٌ - skilled).
  • لِصَبْرِ الْمُسْلِمِينَ (li-ṣabri al-muslimīna) – For the patience of the Muslims. (Genitive after لِـ and part of an إِضَافَة construct).
  • قَابَلْتُ عُمَّالًا مُجْتَهِدِينَ (qābaltu 'ummālan mujtahidīna) – I met hardworking laborers. (عُمَّالًا is broken plural for عَامِلٌ but مُجْتَهِدِينَ is sound masculine plural, both accusative).
  • مَسْؤُولُونَ كِبَارٌ (mas'ūlūna kibārun) – Senior officials. (Nominative. مَسْؤُولٌ - official, كَبِيرٌ - big/senior).
  • أَهْدَافُ الْمُشَارِكِينَ (ahdāfu al-mushārikīna) – The goals of the participants. (Genitive, نُونٌ dropped in إِضَافَة).
These examples demonstrate the flexibility of the Sound Masculine Plural and how it integrates with other grammatical components like adjectives and prepositions, always maintaining case agreement. Pay attention to how the suffixes ـُونَ and ـِينَ seamlessly blend with the preceding word, maintaining its "sound" nature.

Real Conversations

The Sound Masculine Plural is not confined to formal texts; it's a vibrant part of everyday Arabic speech, social media, and professional communication. Observing its use in authentic contexts provides valuable insight.

- Social Media Comments: You'll often see this plural in comments, captions, and discussions. For instance, after a successful event, a post might read: شُكْرًا لِكُلِّ الْمُنَظِّمِينَ وَالْحَاضِرِينَ! (shukran li-kulli al-munaẓẓimīna wa al-ḥāḍirīna!) – Thanks to all the organizers and attendees! (Both الْمُنَظِّمِينَ and الْحَاضِرِينَ are genitive after لِكُلِّ).

- Work Emails/Messaging: In professional settings, especially in industries with many specialists, this plural is common.

- يَرْجَى مِنْ جَمِيعِ الْمُدِيرِينَ تَقْدِيمُ التَّقَارِيرِ. (yarjā min jamī'i al-mudirīna taqdīmu at-taqārīri.) – All managers are requested to submit reports. (الْمُدِيرِينَ is genitive after جَمِيعِ).

- فَرِيقُ الْمُهَنْدِسِينَ يُوَاجِهُ تَحَدِّيَاتٍ. (farīqu al-muhandisīna yuwājihu taḥaddiyātin.) – The team of engineers is facing challenges. (الْمُهَنْدِسِينَ is genitive in إِضَافَة).

- Casual Discussions (with dialectal variations): While MSA strictly adheres to the ـُونَ / ـِينَ distinction, many Arabic dialects often simplify this by predominantly using the ـِينَ ending for all cases. However, understanding the MSA rule is crucial for comprehension and formal speech.

- In a gathering: الْأَصْدِقَاءُ هُنَاكَ يَنْتَظِرُونَكَ. (al-aṣdiqā’u hunāka yantaẓirūnaka.) – The friends over there are waiting for you. (الْأَصْدِقَاءُ is a broken plural, but the verb يَنْتَظِرُونَ is plural masculine).

- Referring to a group of men working: الشَّبَابُ شَغَّالِينَ. (ash-shabābu shaghghālīna.) – The young men are working. (Here, شَغَّالِينَ (working) is an adjective taking the ـِينَ ending, common in many dialects even in nominative contexts).

Observing these real-world examples will help you internalize not just the grammar, but also the natural flow and rhythm of Arabic communication.

Quick FAQ

Here are quick answers to common questions about the Sound Masculine Plural, summarizing key points for learners.
  • Q: Can I use ـُونَ or ـِينَ for a group composed only of women?
  • A: No. For groups exclusively of women, you must use the Sound Feminine Plural (جَمْعُ الْمُؤَنَّثِ السَّالِمُ), which typically ends in ـَاتٌ (-āt). For example, مُدَرِّسَاتٌ (female teachers) or طَالِبَاتٌ (female students).
  • Q: What if the group is a mix of men and women?
  • A: In Arabic grammar, the masculine plural takes precedence for mixed-gender groups. If there's at least one male in the group, the entire group is referred to using the masculine plural form (either Sound Masculine or a broken plural, if applicable).
  • Q: Does every masculine human noun take this plural?
  • A: No. While many do, especially modern professions and adjectives, a significant number of common human-referring nouns have broken plurals (جَمْعُ التَّكْسِيرِ) that you must memorize. Examples include رَجُلٌ (man) -> رِجَالٌ, وَلَدٌ (boy) -> أَوْلَادٌ, طَبِيبٌ (doctor) -> أَطِبَّاءٌ.
  • Q: Is the نُونٌ (nūn) at the end of ـُونَ / ـِينَ always pronounced?
  • A: Yes, in standard Arabic pronunciation, the نُونٌ is always pronounced. The only exception is when the plural noun is the first term in an إِضَافَةٌ (genitive construction), in which case the نُونٌ is dropped (e.g., مُعَلِّمُو الْمَدْرَسَةِ – the teachers of the school). For A1 learners, it's safer to always keep the نُونٌ.
  • Q: If I'm unsure about the grammatical case in informal speech, which ending should I use?
  • A: In many Arabic dialects and informal contexts, the ـِينَ ending is often used universally, regardless of grammatical case. While not grammatically correct in MSA, it's a common simplification in casual spoken Arabic. However, for formal communication or when learning MSA, strive for accuracy with both endings.
  • Q: Do adjectives have to agree with the Sound Masculine Plural noun?
  • A: Yes, absolutely. An adjective modifying a Sound Masculine Plural noun must also take the Sound Masculine Plural form and agree in grammatical case (nominative, accusative, or genitive). For example, الْمُسَافِرُونَ الْمُتْعَبُونَ (the tired travelers) or شَكَرْتُ الْفَائِزِينَ الْمَسْرُورِينَ (I thanked the happy winners).
  • Q: Why is it called "Sound" (سَالِمُ)?
  • A: It's called "sound" because the singular form of the word remains "healthy" or intact, without any internal changes to its letters or vowel patterns, when forming the plural. Only suffixes are added.
  • Q: Is this plural used in the Quran or classical Arabic texts?
  • A: Yes, extensively. The Sound Masculine Plural is fundamental to classical Arabic, including the Quran. You will encounter words like الْمُؤْمِنُونَ (the believers), الصَّابِرُونَ (the patient ones), and الصَّالِحِينَ (the righteous ones) throughout such texts, always adhering to the precise case endings.

⚠️

The 'Lemon' Trap

Not every word ending in ūn is a plural. Laymūn (lemon) and Zaytūn (olive) are singular fruits. Don't try to peel the ūn off them!
🎯

Mixed Groups Rule

In Arabic, the masculine plural is the default for mixed-gender groups. If there is even one man in a group of 100, use ون or ين.
💬

Dialect Shortcut

In many spoken dialects (like Egyptian or Levantine), the ūn ending is rarely used. People use īn for almost everything. It’s the ultimate life-hack for speaking!

Smart Tips

Always check if it's a human masculine noun.

الْمُعَلِّمِين يَدْرُسُونَ → الْمُعَلِّمُونَ يَدْرُسُونَ

Use the 'īn' suffix.

رَأَيْتُ الْمُعَلِّمُون → رَأَيْتُ الْمُعَلِّمِينَ

Ensure you don't drop the 'n' unless it's an idafa.

مُعَلِّمُون الْمَدْرَسَةِ → مُعَلِّمُو الْمَدْرَسَةِ

Don't worry too much about the case endings.

الْمُعَلِّمُونَ هُنَا → الْمُعَلِّمِين هُنَا

Pronunciation

oo-n

ūn

Long 'u' sound followed by 'n'.

ee-n

īn

Long 'ee' sound followed by 'n'.

Statement

الْمُعَلِّمُونَ هُنَا ↘

Falling intonation at the end.

Memorize It

Mnemonic

Think of 'ūn' as 'Up' (subject) and 'īn' as 'In' (inside the object).

Visual Association

Imagine a group of men standing on a platform (Subject/Up/ūn) and another group sitting inside a box (Object/In/īn).

Rhyme

For the subject use the ūn, for the object use the īn.

Story

The farmers (فَلَّاحُون) were standing in the field. I saw the farmers (فَلَّاحِين) from my car. I gave water to the farmers (فَلَّاحِين).

Word Web

مُعَلِّمُونمُهَنْدِسُونمُوَظَّفُونمُسَافِرُونفَلَّاحُونمُتَابِعُون

Challenge

Write 3 sentences using 'ūn' and 3 using 'īn' today.

Cultural Notes

In Egyptian dialect, the 'n' is often dropped in casual speech.

Similar to MSA, but often uses 'īn' for both cases.

Strict adherence to MSA rules in formal settings.

Derived from Proto-Semitic case endings.
