The Arabic Definite Article ال

In this Arabic grammar lesson, we will study the Arabic definite article, written ال. This topic is essential for students who want to learn Arabic online, understand the difference between definite and indefinite nouns, and improve their Arabic reading skills.

The Arabic definite article ال usually corresponds to “the” in English. It is very common in Modern Standard Arabic, Arabic grammar and Quranic Arabic texts.

What Is the Arabic Definite Article?

The Arabic definite article is made of two letters: ا and ل. It is often called alif lam.

When it is added before a noun, it makes the noun definite.

• كِتَابٌ: a book;
• الْكِتَابُ: the book;
• قَلَمٌ: a pen;
• الْقَلَمُ: the pen.

Definite and Indefinite Nouns in Arabic

An indefinite noun refers to something in a general way. In Arabic, it often carries tanwin at the end.

• كَلْبٌ: a dog;
• كِتَابٌ: a book;
• مَسْجِدٌ: a mosque.

A definite noun refers to something specific. It is often preceded by the article ال.

• الْكَلْبُ: the dog;
• الْكِتَابُ: the book;
• الْمَسْجِدُ: the mosque.

How to Use ال in Arabic

To make a noun definite in Arabic, you generally add ال to the beginning of the word.

Why ال Removes Tanwin

In Arabic, a noun generally cannot take both the definite article ال and tanwin at the same time.

Tanwin often marks an indefinite noun, while ال marks a definite noun. This is why tanwin disappears when the definite article is added.

• كِتَابٌ becomes الْكِتَابُ;
• قَلَمٌ becomes الْقَلَمُ;
• بَيْتٌ becomes الْبَيْتُ.

Arabic Moon Letters

Moon letters are letters before which the ل of the article ال is pronounced.

Examples:

• الْقَلَمُ: the pen;
• الْبَابُ: the door;
• الْكِتَابُ: the book;
• الْقَمَرُ: the moon;
• الْمَسْجِدُ: the mosque.

In these examples, the sound of the letter ل is pronounced clearly.

Arabic Sun Letters

Sun letters are letters before which the ل of the article ال is not pronounced. The following letter is doubled with a shadda.

Examples:

• الشَّمْسُ: the sun;
• الطَّبِيبُ: the doctor;
• السَّمَكُ: the fish;
• الرَّجُلُ: the man;
• التَّاجِرُ: the merchant.

This rule is very important for Arabic pronunciation and correct Arabic reading with the definite article ال.
