Arabic Pronunciation: Solar Letters and the Shadda Secret

Solar Letters & The Silent "Lam"

Understanding Assimilation and the Shadda ( ّ )

In Arabic, the definite article is Al- (ال). However, the Lām (ل) is not always pronounced. When followed by a Solar Letter, the 'L' sound merges into the next letter, making it sound "doubled."

The Shadda ( ّ ) Rule

When the Lām is dropped, we place a Shadda on the first letter of the noun to show that it is now "stronger" or doubled. This process is called Assimilation.

Sun (Shams)

اَلشَّمْسُ

Ash-Shamsu
(The 'L' is silent)

Moon (Qamar)

اَلْقَمَرُ

Al-Qamaru
(The 'L' is heard)

Which letters are "Solar"?

There are 14 Solar Letters. They are mostly letters produced at the front of the mouth (near the teeth):

ت ث د ذ ر ز س ش ص ض ط ظ ل ن

(T, Th, D, Dh, R, Z, S, Sh, S, D, T, Z, L, N)

Pronunciation Guide

Word	With "Al-"	Pronunciation	Type
Deen (Religion)	اَلدِّينُ	Ad-Deenu	Solar
Rajul (Man)	اَلرَّجُلُ	Ar-Rajulu	Solar
Bab (Door)	اَلْبَابُ	Al-Baabu	Lunar

Practice Tip: When you see a Shadda immediately after the Lām, it is a visual cue that the Lām is silent! Try pronouncing An-Nooru (اَلنُّورُ - The Light).
