Arabic Grammatical Cases Explained

In this Arabic grammar lesson, we will study Arabic grammatical cases, called الإِعْرَابُ. This topic is essential for students who want to learn Arabic online, understand final vowels and improve their Arabic reading skills.

In Arabic, the ending of a word can change according to its function in the sentence. These changes mainly affect declinable nouns and help identify whether a word is in the nominative, accusative or genitive case.

What Are Arabic Grammatical Cases?

Grammatical cases show the function of a word in a sentence. In Arabic, they often affect the final vowel of the word.

An Arabic noun can be in one of three main cases:

• حَالَةُ الرَّفْعِ: the nominative case;
• حَالَةُ النَّصْبِ: the accusative case;
• حَالَةُ الْجَرِّ: the genitive case.

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

What Is I‘rab in Arabic?

The term الإِعْرَابُ refers to the grammatical analysis of a word according to its position in the sentence. It explains why the final vowel of a word changes.

For example, a word may change depending on:

• its role in the sentence;
• the presence of a preposition;
• its function after a verb;
• whether it is definite or indefinite.

Understanding i‘rab helps you read vocalized Arabic more accurately and better understand Arabic sentence structure.

Declinable and Indeclinable Words

In Arabic, some words are declinable and others are indeclinable.

• A declinable word is called مُعْرَبٌ.
• An indeclinable word is called مَبْنِيٌّ.

A declinable word can change its final vowel according to its grammatical case. An indeclinable word generally keeps the same form, even when its function changes in the sentence.

The Nominative Case in Arabic

The nominative case is called حَالَةُ الرَّفْعِ in Arabic. It is often marked by a damma or dammatain at the end of the word.

• ـُ: damma;
• ـٌ: dammatain.

The nominative case often appears in nominal sentences, especially for the subject or the information given about the subject.

Examples:

• الْكِتَابُ جَدِيدٌ: the book is new;
• مُحَمَّدٌ طَالِبٌ: Muhammad is a student.

The Accusative Case in Arabic

The accusative case is called حَالَةُ النَّصْبِ in Arabic. It is often marked by a fatha or fathatain at the end of the word.

• ـَ: fatha;
• ـً: fathatain.

The accusative case appears in several grammatical situations, for example after certain verbs or in specific sentence constructions.

Simple examples:

• رَأَيْتُ كِتَابًا: I saw a book;
• فَتَحَ الطَّالِبُ الْبَابَ: the student opened the door.

The Genitive Case in Arabic

The genitive case is called حَالَةُ الْجَرِّ in Arabic. It is often marked by a kasra or kasratain at the end of the word.

• ـِ: kasra;
• ـٍ: kasratain.

The genitive case often appears after Arabic prepositions, called حُرُوفُ الْجَرِّ.

Examples:

• فِي الْبَيْتِ: in the house;
• عَلَىٰ مَكْتَبٍ: on a desk;
• مِنَ الْمَدْرَسَةِ: from the school.
