What Are Sun and Moon Letters in Arabic?

In Arabic, the alphabet is divided into two categories known as sun letters (الحروف الشمسية) and moon letters (الحروف القمرية). This classification is based on the phonetic behavior of letters when preceded by the definite article “ال” (al-), which means “the” in English.

The distinction affects how the “ل” (lam) in the definite article is pronounced. With sun letters, the “ل” is assimilated or merged into the following letter, causing a doubling of the sun letter’s sound. With moon letters, the “ل” is pronounced clearly, and the sun letter retains its original sound.

Why Is This Important?

• Correct pronunciation: Mastering sun and moon letters ensures accurate articulation of words.
• Proper reading and writing: Understanding these letters helps in reading Arabic fluently and writing correctly.
• Improved listening skills: Recognizing the difference aids in better comprehension during conversations.

List of Sun and Moon Letters

Arabic has 28 letters, split into 14 sun letters and 14 moon letters. Knowing this list is fundamental to applying the rules of the definite article correctly.

Sun Letters (الحروف الشمسية)

Sun letters cause the “ل” in “ال” to be silent, and their initial consonant is doubled (geminated). The sun letters are:

• ت (ta)
• ث (tha)
• د (dal)
• ذ (dhal)
• ر (ra)
• ز (zay)
• س (sin)
• ش (shin)
• ص (sad)
• ض (dad)
• ط (ta)
• ظ (za)
• ل (lam)
• ن (nun)

Moon Letters (الحروف القمرية)

Moon letters do not assimilate the “ل” in “ال”; both the “ل” and the moon letter are pronounced clearly. The moon letters are:

• ا (alif)
• ب (ba)
• ج (jim)
• ح (ha)
• خ (kha)
• ع (ain)
• غ (ghain)
• ف (fa)
• ق (qaf)
• ك (kaf)
• م (mim)
• ه (ha)
• و (waw)
• ي (ya)

Rules for Pronouncing the Definite Article with Sun and Moon Letters

Definite Article with Sun Letters

When a word begins with a sun letter, the “ل” in the definite article “ال” is silent, and the sun letter is doubled. This doubling is represented by a diacritical mark called shadda ( ّ ) above the sun letter.

Examples:

• الشمس (ash-shams) – the sun
• النهار (an-nahar) – the daytime
• الرجل (ar-rajul) – the man

Notice how the “ل” is not pronounced, and the sun letter is pronounced with emphasis due to gemination.

Definite Article with Moon Letters

When a word begins with a moon letter, the “ل” in “ال” is pronounced clearly, and the moon letter is pronounced normally without doubling.

Examples:

• القمر (al-qamar) – the moon
• الباب (al-bab) – the door
• الماء (al-maa’) – the water

In these examples, both the “ل” and the moon letter are articulated distinctly.

How to Identify Sun and Moon Letters in Words

Since the sun and moon letter classification depends on the first letter of the word following “ال,” knowing the alphabet and these groups is vital. Here are tips to identify them:

• Memorize the lists of sun and moon letters.
• Check the first letter of the noun or adjective after the definite article.
• Apply the assimilation rule for sun letters and the clear pronunciation rule for moon letters.

Practice with words and sentences will help internalize these rules.

Many learners struggle with the sun and moon letters because the distinction is subtle but impactful. Common errors include:
