In our previous post on how to say “the” in Arabic, we learned that the definite article is simply the prefix الـ
. You just attach it directly to the beginning of a word. Simple, right?
But if you listen closely to native speakers, you’ll notice a twist. Sometimes you hear the ل clearly, and sometimes it vanishes completely.
This isn’t a random exception designed to confuse you. It’s actually a natural, physical shortcut your mouth takes to make speaking smoother and faster. It all comes down to a brilliant system known as sun and moon letters. Mastering the Arabic sun and moon letters rules is your secret to sounding like a native.
Before we dive into the rules of pronunciation, it is crucial that you have a solid grasp of the basics. If you are not yet confident identifying the letters, start with our complete guide on how to read the Arabic alphabet first.
The vanishing sound
Think of the Arabic word for moon, which is قمر
. When you add the definite article to say “the moon,” you say القمر
. The ل sound stays crystal clear.
Now, think of the word for sun, which is شمس
. When you add “the,” you don’t hear the ل at all. Instead, it drops completely, and the first letter of the word doubles up. You say الشمس
(“ash” + “shams”).
The mouth shortcut
Do you really have to memorize two long lists of letters to know when the sound drops?
Not at all! You just need to understand how your mouth works. It’s all about where the sound is produced:
If a letter is made at the front of your mouth, like (ت (التاء
or (د (الدال
or (س (السين
, your tongue is already in position. It naturally blends into the next sound, so the ل disappears and the next letter gets emphasized. These are your sun letters.
Notice how the ل sound in السلام
is not pronounced in this video teaching common everyday phrases in Modern Standard Arabic.
If a letter is made deeper in the back of your mouth or throat, like (ب (الباء
or (م (الميم
or (ك (الكاف
, your tongue isn’t in a position to blend. So, the ل stays clearly pronounced. These are your moon letters.

Street rules vs. textbooks
If you study Modern Standard Arabic, this system is completely fixed. But in everyday spoken Arabic, native speakers love to bend the rules to make speaking even smoother!
Take the letters (ج (الجيم
and (ك (الكاف
. In Modern Standard Arabic, they are strictly moon letters. You will always hear the ل clearly, like in الجمل
(the camel) and الكتاب
(the book).
Notice how the speaker clearly pronounces the ل sound at the beginning of the video because it is followed by the letter jīm (ج)
, which is always a moon letter in Modern Standard Arabic, as in this video.
But if you are listening to Egyptian Arabic, these two letters develop a dual personality. While many people still pronounce them as normal moon letters, they can also suddenly act like sun letters! Depending on the speaker, the ل might vanish completely, and the first letter doubles up instead when saying الجمل
(“ag” + “gamal”) or الكتاب
(“ak” + “kitab”).
Pay attention to the first word in the video and notice how the ل sound is not pronounced because the speaker is using Egyptian Arabic. Listen a few more times and also notice how the letter gīm (ج)
is pronounced differently in Egyptian Arabic compared to Modern Standard Arabic and many other dialects.
In Levantine Arabic, the letter (ج (الجيم
also has this dual personality. It functions as a moon letter, but native speakers will often treat it like a sun letter and drop the ل completely when saying words like الجمل
. Sometimes, the initial vowel almost disappears entirely!
In this Syrian Arabic video, the ل sound is also dropped in the word beginning with jīm (ج)
, and the initial vowel sound is almost dropped as well.
Closing note
You don’t need to memorize the Arabic sun and moon letters today. Once you start listening to real-world Arabic, your tongue will naturally take these shortcuts because they physically make sense.
