K-T-B

K-T-B is a triconsonantal root of a number of Arabic words, typically those having to do with writing. The words for office, writer, and record all reflect this root. Most notably, the Arabic word "kitab" (book) is also used in a number of Semitic and Indo-Iranian languages, as well as Turkish. One cultural example would be the Arabic expression transliterated as "Maktoub", which may be translated as: It is written. Another would be the Koutoubia mosque of Marrakech, whose name is taken from the librarians and booksellers who once occupied that area.
