The Arabic Broken Plural Pattern مَفَاعِلُ

The irregular plural in Arabic is an essential concept for understanding Arabic grammar and expanding your vocabulary. Unlike the regular plural, the irregular plural is not always formed by simply adding an ending to the singular word. It often follows an internal pattern.

In this lesson, we will study a frequent masculine broken plural pattern: مَفَاعِلُ. This pattern is used to form the plural of several common Arabic nouns, such as مَسْجِدٌ, which becomes مَسَاجِدُ.

This lesson is useful for beginners, but also for students who want to improve their literary Arabic, Modern Standard Arabic and Quranic Arabic. Understanding Arabic broken plurals helps students read more accurately, translate better and memorize Arabic vocabulary more effectively.

What Is an Irregular Plural in Arabic?

In Arabic, there are several types of plurals. Some plurals are regular because they are formed by adding an ending to the singular word. Others are irregular because the internal structure of the word changes.

The irregular plural is often called the broken plural. It refers to a transformation of the word according to a specific pattern.

Example:

• مَسْجِدٌ: a mosque;
• مَسَاجِدُ: mosques.

Here, the word does not simply receive an ending. Its internal structure changes.

Understanding the Pattern مَفَاعِلُ

The pattern مَفَاعِلُ is one of the frequent broken plural patterns in Arabic. It works as a reference form to help students recognize and memorize certain plurals.

In this pattern, the consonants of the singular word are placed into a specific structure with precise vowels. This structure produces a recognizable plural form.

Main example:

• pattern: مَفَاعِلُ;
• singular: مَسْجِدٌ;
• plural: مَسَاجِدُ.

The word مَسَاجِدُ therefore follows the pattern مَفَاعِلُ.

How This Arabic Plural Pattern Works

The pattern مَفَاعِلُ is based on the internal organization of the word. For learners, the goal is not always to guess the plural by themselves, but to recognize the form and memorize it with its singular.

The Singular and the Broken Plural

The singular is the basic form of the word. The broken plural is a transformed form that may change the vowels, the length of the word or the internal structure.

Example:

• دَفْتَرٌ: a notebook;
• دَفَاتِرُ: notebooks.

The plural دَفَاتِرُ also follows the pattern مَفَاعِلُ.

The Role of Vowels in the Pattern

In Arabic broken plurals, vowels play an important role. They help students recognize the pattern and distinguish the singular from the plural.

In the pattern مَفَاعِلُ, a similar vowel structure appears in several words:

• مَسَاجِدُ;
• دَفَاتِرُ;
• مَكَاتِبُ;
• فَنَادِقُ.

This is why it is useful to learn Arabic nouns with their plural form from the beginning.

Table of Examples with the Pattern مَفَاعِلُ

This table shows that several Arabic nouns follow the same irregular plural pattern.

Examples of Sentences with the مَفَاعِلُ Plural

Here are several examples to understand how this broken plural is used in Arabic sentences.

• هَذَا دَفْتَرُ حَامِدٍ: this is Hamid’s notebook.
• هَذِهِ دَفَاتِرُ حَامِدٍ: these are Hamid’s notebooks.
• هَذَا مَكْتَبُ الْمُدَرِّسِ: this is the teacher’s desk.
• هَذِهِ مَكَاتِبُ الْمُدَرِّسِينَ: these are the teachers’ desks.
• هَذَا فُنْدُقٌ غَالٍ: this hotel is expensive.
• هَذِهِ فَنَادِقُ غَالِيَةٌ: these hotels are expensive.

In these examples, the singular and the plural have different forms. Students should therefore learn each noun with its plural.

Why Should Arabic Broken Plurals Be Memorized?

In Arabic, it can sometimes be difficult to guess the irregular plural of a noun automatically. The same type of noun may have different plural forms depending on usage, vocabulary and context.

This is why it is recommended to learn Arabic nouns together with their plural form from the beginning.

For example, instead of learning only مَسْجِدٌ, it is better to learn:

• مَسْجِدٌ: a mosque;
• مَسَاجِدُ: mosques.

This method improves memorization, reading and comprehension of Arabic texts.

Difference Between Regular and Irregular Plurals

The regular plural is generally formed by adding an ending. The irregular plural changes the internal structure of the word.

This difference is fundamental for progressing in Arabic grammar and Arabic vocabulary.

Common Mistakes to Avoid

Here are some common mistakes made by students who learn Arabic broken plurals:

• thinking that all Arabic plurals are regular;
• trying to guess the plural without having learned it;
• confusing several broken plural patterns;
• forgetting the vowels of the pattern مَفَاعِلُ;
• not learning the singular noun with its plural form.

These mistakes are normal at the beginning. They gradually decrease with reading, repetition and correction.
