Arabic Genitive Case (Al-Jarr): Possession and Prepositions
Grammar Rule in 30 Seconds
In Arabic, nouns following a preposition or forming a possessive (Idafa) must end in the 'Kasra' (i) sound.
- After a preposition, the noun takes a Kasra: 'Fi al-bayti' (In the house).
- In an Idafa (possession), the second noun takes a Kasra: 'Kitab al-waladi' (The boy's book).
- If the noun is indefinite, use 'Tanwin Kasr' (-in): 'Fi baytin' (In a house).
Overview
In Arabic grammar, the Genitive Case, known as الجَرّ (al-jarr) or الخَفْض (al-khafḍ), marks a noun's grammatical relationship within a sentence. It primarily indicates possession or follows a preposition. Understanding al-jarr is crucial for constructing grammatically correct and coherent Arabic sentences, especially in Modern Standard Arabic (MSA).
This case signifies that a noun is either the object of a preposition (حَرْفُ جَرٍّ) or the possessor in an idafa (إِضَافَة) construction. Failing to apply the genitive case where required is a fundamental grammatical error in formal Arabic, akin to saying "he go to store" instead of "he goes to the store" in English. Mastery of al-jarr ensures clarity and precision in your communication, reflecting a deeper understanding of Arabic syntactic structures.
How This Grammar Works
الإِعْرَاب (al-i'rāb), where the final vowel or suffix of a noun changes to reflect its grammatical function. The Genitive case is one of three primary cases, alongside the Nominative (الرَّفْعُ - al-rafʿ) for subjects and the Accusative (النَّصْبُ - an-naṣb) for direct objects. Each case has a distinct marker that signals the noun's role.kasra (ـِ). This short vowel, pronounced 'i' or 'ee', is placed on the last letter of the noun. When a noun is indefinite and in the genitive case, it takes a double kasra, called تَنْوِينُ الكَسْرِ (tanwīn al-kasr), written as ـٍ.al-jarr is one of dependency: certain grammatical elements inherently demand that the subsequent noun be in the genitive case. Prepositions like في (in) or مِنْ (from) act as عَوَامِلُ الجَرِّ (ʿawāmil al-jarr - genitive operators), compelling the following noun to adopt the genitive form. Similarly, in a possessive idafa construction (X of Y), the 'Y' (the possessor) is grammatically dependent on the 'X' (the possessed) and must always be in the genitive case.كِتابٌ (a book, Nominative indefinite). If it follows the preposition في (in), it becomes فِي كِتابٍ (in a book), taking tanwīn al-kasr. If it's the possessor in بابُ كِتابٍ (the door of a book), it also takes tanwīn al-kasr.Formation Pattern

kasra (ـِ) on their final letter. If the noun is indefinite, it takes tanwīn al-kasr (ـٍ).

القَلَمُ (the pen) | القَلَمِ (of the pen) | قَلَمٌ (a pen) | قَلَمٍ (of a pen) |
ذَهَبْتُ إِلَى المَدْرَسَةِ. (I went to the school.) - المَدْرَسَةِ is genitive due to إِلَى.

تَكَلَّمْتُ عَنِ الأَطْفالِ. (I spoke about the children.) - الأَطْفالِ is genitive due to عَنْ.

ـَانِ (-āni) ending changes to ـَيْنِ (-ayni). The final نُون (nūn) is dropped in an idafa construction.

نَظَرْتُ إِلَى الطَّالِبَيْنِ. (I looked at the two students.) - الطَّالِبَيْنِ is genitive.
جَمْعُ المُذَكَّرِ السَّالِمِ)
ـُونَ (-ūna) ending changes to ـِينَ (-īna) for the genitive (and accusative) case. The final نُون (nūn) is dropped in an idafa construction.
مُهَنْدِسُونَ (engineers) | مُهَنْدِسِينَ (of engineers) |
مُسْلِمُونَ (Muslims) | مُسْلِمِينَ (of Muslims) |

جَمْعُ المُؤَنَّثِ السَّالِمِ)
kasra (ـِ) on their final ت (tā’). If indefinite, they take tanwīn al-kasr (ـٍ). This is a key point: they take a kasra even though their nominative form ends in damma (ـَاتٌ or ـَاتُ).
السَّيَّارَاتُ (the cars) | السَّيَّارَاتِ (of the cars) | سَيَّارَاتٌ (cars) | سَيَّارَاتٍ (of cars) |
نَظَرْتُ إِلَى الطَّالِبَاتِ. (I looked at the female students.) - الطَّالِبَاتِ is genitive.
الأسْمَاءُ الخَمْسَةُ)
أَبٌ - father, أَخٌ - brother, حَمٌ - father-in-law, فَمٌ - mouth, ذُو - owner of) are irregular. In the genitive case, they take يَاء (yāʾ) as their marker.
أَبٌ | أَبُوكَ (your father) | أَبِيكَ (of your father) |
أَخٌ | أَخُوهُ (his brother) | أَخِيهِ (of his brother) |
ذُو | ذُو عِلْمٍ (owner of knowledge) | ذِي عِلْمٍ (of one with knowledge) |
سَلَّمْتُ عَلَى أَخِيكَ. (I greeted your brother.) - أَخِيكَ is genitive.
الاسْمُ المَقْصُورُ وَ المَنْقُوصُ)
kasra, even though they are grammatically in the genitive case. These include nouns ending in أَلِف مَقْصُورَة (e.g., مُسْتَشْفَى - hospital) or أَلِف مَمْدُودَة (e.g., صَحْرَاءُ - desert), and الاسْمُ المَنْقُوصُ (e.g., القَاضِي - the judge).
ذَهَبْتُ إِلَى الْمُسْتَشْفَى. (I went to the hospital.) - المُسْتَشْفَى is genitive, but the kasra is 'estimated' (مُقَدَّرَةٌ).
المَمْنُوعُ مِنَ الصَّرْفِ)
tanwīn and take a fatḥa (ـَ) instead of a kasra in the genitive case when they are indefinite or not part of an idafa. For example, مَرَرْتُ بِأَحْمَدَ (I passed by Ahmad) where أَحْمَدَ is a diptote.

Meanings
The Genitive case (Al-Jarr) is used to mark nouns that are governed by prepositions or that act as the second part of a possessive construction.
Prepositional Genitive
Nouns following particles like 'fi' (in), 'min' (from), or 'ila' (to) must be in the genitive case.
“أذهب إلى المدرسة (I go to school)”
“خرج من الغرفة (He left the room)”
Idafa (Possession)
When two nouns are linked to show possession, the second noun (the possessor) is in the genitive case.
“سيارة الرجل (The man's car)”
“باب البيت (The house's door)”

Smart Tips
Always pause and check the last letter of the noun.
Check if you added 'al-' to the first word—if so, remove it!
Remember to add the 'n' sound (tanwin).
Check if the plural is sound or broken.
Pronunciation
Kasra
A short 'i' sound like in 'sit'.
Tanwin Kasr
An 'in' sound at the end of the word.

Memorize It
Mnemonic
Genitive is the 'i' case. Think: 'I' am in the 'i' case.
Visual Association
Imagine a house (bayt). You are inside it, and the floor is made of 'i' tiles. Every time you step on a preposition, you land on an 'i' tile.
Rhyme
When you see a preposition, give the noun an 'i' position.
Story
Ahmed walks into a house. He says 'Fi al-bayti'. He sees his friend's cat, 'Qittat al-sadiqi'. He is happy because he used the 'i' sound correctly.
Word Web
Challenge
Write 5 sentences using different prepositions and check if you used the -i ending.
Cultural Notes
In speech, case endings are often dropped entirely.
Similar to Levantine, endings are rarely pronounced.
Endings are strictly observed in formal speech and writing.
The Genitive case is a remnant of the Proto-Semitic case system.
