K-T-B

K-T-B is a triconsonantal root of a number of Semitic 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 Mishnaic expression Katuv or the cognate 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.

The Hebrew fricatives transcribed as "ḵ" and "ḇ" can also be transcribed in a number of other ways, such as "ch" and "v", which are pronounced [χ] and [v], respectively. They are transliterated "ḵ" and "ḇ" on this page to retain the connection with the pure consonantal root k-t-b. Also notice that in Modern Hebrew, there is no gemination. In Hebrew, the root is used with the meaning of 'writing' but not for the noun for 'book', which is sefer. To a lesser extent in Hebrew, the word "Katuv" as a noun refers to the Tanakh.

Contrastive Arabic-Hebrew

A contrastive presentation of part of this can be as follows:

Other languages

In Tigrinya and Amharic, this root survives only in the noun kitab, meaning "amulet", and the verb "to vaccinate". Ethiopic-derived languages use a completely different root (ṣ-ḥ-f) for the verb "to write" (this root exists in Arabic and is used to form words with a close meaning to "writing", such as ṣaḥāfa "journalism", and ṣaḥīfa "newspaper" or "parchment"). In Persian, the word Kitab is used to refer to a religious text only.
