Sun and moon letters
In Arabic and Maltese, the consonants are divided into two groups, called the sun letters or solar letters (Arabic: حروف شمسية ḥurūf šamsiyyah) and moon letters or lunar letters (حروف قمرية ḥurūf qamariyyah), based on whether or not they assimilate the lām (ﻝ l)[1] of a preceding definite article al- (الـ). These names come from the fact that the word for "the sun", aš-šams, assimilates the lām, while the word for "the moon", al-qamar, does not.

[edit] Rule
When followed by a sun letter, the l of the Arabic definite article al- assimilates to the initial consonant of the following noun, resulting in a doubled consonant. For example, for "the Nile", one does not say al-Nīl, but an-Nīl. When the definite article is followed by a moon letter, no assimilation takes place.
Sun letters represented coronal consonants in the classical language. Since the article, al-, ends in a coronal consonant, it lends itself to assimilation with these sounds.
The 14 sun letters are ﻥ ﻝ ﻅ ﻁ ﺽ ﺹ ﺵ ﺱ ﺯ ﺭ ﺫ ﺩ ﺙ ﺕ; transliterated from left to right t, ṯ, d, ḏ, r, z, s, š, ṣ, ḍ, ṭ, ẓ, l, n.
The 14 moon letters are ه ﻱ ﻭ ﻡ ﻙ ﻕ ﻑ ﻍ ﻉ ﺥ ﺡ ﺝ ﺏ ء; transliterated from left to right ʾ, b, ǧ, ḥ, ḫ, ʿ, ġ, f, q, k, m, w, y, h.
[edit] Ǧīm
The letter ج ǧ has three standard pronunciations: [ɡ], [ʒ] or [d͡ʒ] in accents of Modern Standard Arabic as well as varieties of Arabic today. However, it represented a palatalized voiced velar plosive, /ɡʲ/ or /ɟ/, in the Koranic Arabic. As a result, its sound does not assimilate the article in formal Arabic and it is classified as a moon letter; it still forms a natural class in varieties like Egyptian Arabic where it is pronounced [ɡ].
[edit] Orthography
In the written language, the ال al- is retained regardless of how it is pronounced.[1] When full diacritics are used, assimilation may be expressed by putting a šaddah on the consonant after the lām, and non-assimilation by placing a sukūn over the lām.
