Maqsour, Manqus and Mamdud Nouns in Arabic

When learning Arabic grammar, some nouns have a special ending and follow specific declension rules. This is the case with maqsour, manqus and mamdud nouns. These three categories are important for understanding Arabic declension, correct reading and sentence analysis.

This lesson is useful for Arabic for beginners, but also for students who want to improve their Modern Standard Arabic, Arabic grammar or Quranic Arabic. It is a general introduction before studying each type of noun in more detail.

Weak Letters in Arabic

In Arabic, some letters are called weak letters. They are:

• ا: alif;
• و: waw;
• ي: ya.

These letters play an important role in Arabic grammar because they can affect pronunciation, spelling and declension.

Why Do Some Arabic Nouns Have Special Declension?

In Arabic, a noun can be in the nominative, accusative or genitive case. These cases are usually shown by marks such as ḍammah, fatḥah or kasrah.

However, when a noun ends with a weak letter or a particular hamzah, these marks are not always visible. This is why some nouns have implied declension, known in Arabic as إِعْرَابٌ تَقْدِيرِيٌّ.

The Maqsour Noun in Arabic

The maqsour noun, called اسْمٌ مَقْصُورٌ, is a declinable noun that ends with alif maqsura, usually written ى. The letter before this alif carries a fatḥah.

Examples:

• مُصْطَفَى: Mustafa;
• هُدَى: Huda;
• الْمُسْتَشْفَى: the hospital;
• الْمَقْهَى: the café.

With this type of noun, the declension marks are usually not visible on the final letter. The word may keep the same form even when its grammatical function changes.

The Manqus Noun in Arabic

The manqus noun, called اسْمٌ مَنْقُوصٌ, is a declinable noun that ends with the letter ي, preceded by a kasrah. It often ends with a long -ī sound.

Examples:

• الْقَاضِي: the judge;
• الْغَالِي: expensive, precious;
• شَادِي: Shady.

The manqus noun follows specific rules. In some situations, the final ya is kept. In other cases, it can be removed, especially when the noun is indefinite, not in annexation and not in the accusative case.

The Mamdud Noun in Arabic

The mamdud noun, called اسْمٌ مَمْدُودٌ, is a noun that ends with a hamzah ء preceded by a long alif.

Examples:

• الصَّحْرَاءُ: the desert;
• حَسْنَاءُ: beautiful;
• زَرْقَاءُ: blue;
• بَنَّاءٌ: builder.

The mamdud noun can be masculine or feminine. Its declension depends on its form and how it is used in the sentence.
