The Mamdud Noun in Arabic: Rules and Examples

To improve your Arabic grammar, it is important to understand the different categories of Arabic nouns. One of these categories is the mamdud noun, called الاسْمُ المَمْدُودُ in Arabic.

This lesson is useful for Arabic for beginners, but also for students who want to improve their Arabic reading, Modern Standard Arabic or Quranic Arabic.

The mamdud noun has a specific form and particular declension rules. Understanding this concept will help you read Arabic words more accurately, recognize their function in a sentence and strengthen your Arabic grammar foundations.

What Is a Mamdud Noun in Arabic?

A mamdud noun, اسْمٌ مَمْدُودٌ, is a singular noun that ends with a hamzah ء preceded by a long alif ا.

In other words, its ending usually takes the following form:

ـاء

The word must be singular. Some words such as نِسَاءٌ, أَهْوَاءٌ or آبَاءٌ also end with ـاء, but they are not treated as mamdud nouns in this rule because they are plural.

Examples of Mamdud Nouns

Here are some common examples of mamdud nouns in Arabic:

These examples show that a mamdud noun can be masculine or feminine. This distinction is important because it affects its declension.

The Hamzah in Mamdud Nouns

The mamdud noun ends with a hamzah ء. This hamzah comes after a long alif. It is not a weak letter like ا, و or ي, but it has a particular behavior in some Arabic words.

For students who learn Arabic online, this rule is useful for improving Arabic reading and Arabic pronunciation. It also helps learners distinguish different noun forms in Arabic texts.

Declension of Masculine Mamdud Nouns

When the mamdud noun is masculine, it is generally declined like a regular singular noun. The three declension marks can appear:

• ḍammah in the nominative case;
• fatḥah in the accusative case;
• kasrah in the genitive case.

Examples:

In these examples, قَرَّاءٌ and بَنَّاءٍ are masculine mamdud nouns. They therefore follow regular declension.

Declension of Feminine Mamdud Nouns

When the mamdud noun is feminine, such as صَحْرَاءُ, خَضْرَاءُ or بَيْضَاءُ, it contains what is called أَلِفُ التَّأْنِيثِ المَمْدُودَةُ, meaning the extended feminine alif.

In this case, the noun is often a diptote, called مَمْنُوعٌ مِنَ الصَّرْفِ in Arabic. This means that it does not take all the usual declension marks.

For this type of noun:

• the nominative usually takes ḍammah;
• the accusative takes fatḥah;
• the genitive also takes fatḥah, except in certain cases.

Examples:

When Does a Feminine Mamdud Noun Take Kasrah?

Like other diptotes, a feminine mamdud noun can take kasrah in the genitive case in specific situations. This happens especially when it is preceded by the definite article ال or when it appears in an annexation structure, known in Arabic as إِضَافَة.

Examples:

This rule is important for students who want to understand Arabic texts accurately, especially when studying Modern Standard Arabic or Quranic Arabic.
