What Are Sun Letters and Moon Letters?
Definition of Sun Letters (الحروف الشمسية)
Sun letters, known in Arabic as “al-ḥurūf ash-shamsiyyah,” are a group of consonants that, when they immediately follow the definite article “ال” (al-), cause the “l” sound in “al-” to assimilate. Instead of pronouncing the “l,” the following Sun letter is doubled or stressed. This phenomenon is called “assimilation” or “idgham.”
Definition of Moon Letters (الحروف القمرية)
Moon letters, or “al-ḥurūf al-qamariyyah,” are the remaining consonants in Arabic. When these letters follow the definite article “ال” (al-), the “l” sound is fully pronounced, and no assimilation occurs. The name “Moon letters” comes from the word “قمر” (qamar), meaning “moon,” which begins with a Moon letter.
List of Sun and Moon Letters
Sun Letters
There are 14 Sun letters in Arabic. They are:
ت (ta), ث (tha), د (dal), ذ (dhal), ر (ra), ز (zay), س (sin), ش (shin), ص (sad), ض (dad), ط (ta), ظ (dha), ل (lam), ن (nun)
A mnemonic to remember them is the phrase: “تَثْرُ دِزْ سَشْ صَضْ طَظْ لَن” (pronounced: t-th-r-d-z-s-sh-s-d-t-dh-l-n).

ا (alif), ب (ba), ج (jim), ح (ha), خ (kha), ع (ain), غ (ghain), ف (fa), ق (qaf), ك (kaf), م (meem), هـ (ha), و (waw), ي (ya)
A common mnemonic is: “ابغ حجك وخف عقيمه” (pronounced: abgh hajjaka wakhaf aqeemahu).
How the Definite Article Works with Sun and Moon Letters
With Sun Letters
When the definite article “ال” precedes a Sun letter, the “l” sound merges into the Sun letter. For example:
– The word “السماء” (the sky) is pronounced “as-samā’” not “al-samā’”.
– “الشمس” (the sun) is pronounced “ash-shams” not “al-shams”.
The Sun letter is then pronounced twice, with a “shadda” (a diacritical mark indicating doubling) in written Arabic.
With Moon Letters
With Moon letters, the “l” in “ال” is clearly pronounced. For example:
– “القمر” (the moon) is pronounced “al-qamar.”
– “الولد” (the boy) is pronounced “al-walad.”
No assimilation occurs, and the pronunciation remains straightforward.
Why Are Sun and Moon Letters Important for Arabic Learners?
Correct Pronunciation
Distinguishing between Sun and Moon letters is key to correct pronunciation, which is crucial for being understood and for understanding others in Arabic. Assimilating or not assimilating the “l” sound can change the meaning of words or make your speech sound unnatural.
Reading and Writing Proficiency
Recognizing the difference helps when reading Arabic aloud, as you’ll know when to double a consonant or pronounce the “l.” In writing, especially with diacritics, knowing when to add a “shadda” can improve your accuracy.
Listening Skills
Understanding this rule aids in listening comprehension since native speakers always apply this assimilation rule, and recognizing it will help you follow conversations more easily.
