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 represent all coronal consonants except ج ǧīm (see below). Since the article al- ends in a coronal consonant, it lends itself to assimilation with these sounds.
The sun and moon letters are as follows:
| Sun letters | ﺕ | ﺙ | ﺩ | ﺫ | ﺭ | ﺯ | ﺱ | ﺵ | ﺹ | ﺽ | ﻁ | ﻅ | ﻝ | ﻥ |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| t | ṯ | d | ḏ | r | z | s | š | ṣ | ḍ | ṭ | ẓ | l | n | |
| Moon letters | ء | ﺏ | ﺝ | ﺡ | ﺥ | ﻉ | ﻍ | ﻑ | ﻕ | ﻙ | ﻡ | ﻭ | ﻱ | ه |
| ʾ | b | ǧ | ḥ | ḫ | ʿ | ġ | f | q | k | m | w | y | h |

Famous quotes containing the word rule:
“Every man needs slaves like he needs clean air. To rule is to breathe, is it not? And even the most disenfranchised get to breathe. The lowest on the social scale have their spouses or their children.”
—Albert Camus (1913–1960)
“While Michael Angelo’s Sistine roof,
His “Morning” and his “Night” disclose
How sinew that has been pulled tight,
Or it may be loosened in repose,
Can rule by supernatural right
Yet be but sinew.”
—William Butler Yeats (1865–1939)
“When any practice has become the fixed rule of the society in which we live, it is always wise to adhere to that rule, unless it call upon us to do something that is actually wrong. One should not offend the prejudices of the world, even if one is quite sure that they are prejudices.”
—Anthony Trollope (1815–1882)
