Kamal ad-Din

Kamal ad-Din (, ''Kamāl ad-Dīn'') is a male Muslim given name or surname (''laqab'' in Arabic), meaning "perfection of the religion" in Arabic.

The name is formed from the elements ''kamāl'' (), ''al-'' (), and ''dīn'' (). It is often transliterated as Kamāl al-Dīn, but because the letter ''dāl'' (, ''d'') is a sun letter, the ''lām'' (, ''l'') of ''al-'' assimilates into the first letter of ''dīn'' in pronunciation, resulting in a doubled consonant.

In Classical Arabic the pronunciation of the name changes depending on its function. Thus, the nominative case of the name is Kamaluddin (''Kamālu’d-Dīn''), the accusative case is Kamaladdin (''Kamāla’d-Dīn''), and the genitive case is Kamaliddin (''Kamāli’d-Dīn''). Provided by Wikipedia
