Indeclinable Words in Arabic

In this Arabic grammar lesson, we will study indeclinable words in Arabic, known as الْكَلِمَاتُ الْمَبْنِيَّةُ. This topic is essential for students who want to learn Arabic online, understand Arabic grammatical cases and improve their Arabic reading skills.

In Arabic, many nouns change their final vowel according to their grammatical case: nominative, accusative or genitive. However, some words never change their final form, regardless of their grammatical function. These words are called indeclinable words.

What Are Indeclinable Words in Arabic?

An indeclinable word is a word whose final form remains unchanged regardless of its position in a sentence. In Arabic grammar, such words are called مَبْنِيٌّ.

Unlike regular nouns, indeclinable words do not change according to the nominative, accusative or genitive case. They also do not take tanwin, which is characteristic of declinable nouns.

This rule is important for Arabic beginners, Modern Standard Arabic, Arabic grammar and Arabic reading.

Difference Between Declinable and Indeclinable Words

A declinable word changes its final vowel depending on its grammatical role. An indeclinable word keeps the same ending regardless of the context.

Indeclinable Question Words

Interrogative tools are generally indeclinable in Arabic. They keep the same form regardless of their grammatical position.

• مَنْ: who?
• أَيْنَ: where?
• مَاذَا: what?

Examples:

• مَنْ أَنْتَ؟: who are you?
• أَيْنَ الأَسَدُ؟: where is the lion?
• مَاذَا عَلَى الْمَكْتَبِ؟: what is on the desk?

Indeclinable Demonstrative Pronouns

Demonstrative pronouns are generally indeclinable as well. They are used to point to people, objects or ideas.

• هَذَا: this (masculine);
• ذَلِكَ: that (masculine);
• هَذِهِ: this (feminine).

Examples:

• هَذَا رَجُلٌ: this is a man;
• هَذِهِ بَطَّةٌ: this is a duck;
• هَذَا بَيْتُ حَامِدٍ: this is Hamid's house;
• وَذَلِكَ بَيْتُ خَالِدٍ: and that is Khalid's house.

Indeclinable Prepositions

Arabic prepositions, known as حُرُوفُ الْجَرِّ, are also indeclinable. Their form never changes.

• عَلَىٰ: on;
• فِي: in;
• إِلَىٰ: to, toward;
• مِنْ: from.

Examples:

• مَاذَا عَلَى الْمَكْتَبِ؟: what is on the desk?
• سَيَّارَةُ عَبَّاسٍ فِي الشَّارِعِ: Abbas's car is in the street;
• خَرَجَ الْمُدَرِّسُ مِنْ غُرْفَةِ الْمُدِيرِ: the teacher left the principal's office.

Indeclinable Personal Pronouns

Personal pronouns are always indeclinable. Their form remains unchanged.

• هُوَ: he;
• هِيَ: she;
• أَنْتَ: you (masculine singular).

Examples:

• مَنْ أَنْتَ؟: who are you?
