Al-Katib

The word

Lisān al-ʿArab starts k-t-b where a modern reader would not: al-katb is joining one thing to another, and kataba al-siqāʾ is he stitched the waterskin closed with two thongs. Writing is that same joining, of letter to letter, which is why the lexicon can put kitāb and katība — a squadron, a body gathered together — under one root. The kātib is the one who does it, and the noun covers the copyist, the clerk who keeps a register, and the man who drafts correspondence.

A trained hand and a name

The last of those was a profession with a training behind it, and Ibn Khaldūn treats the chancery and the writing of letters among the offices of settled rule, requiring of the man who holds it a command of language and of form beyond the mere ability to write. A father known by that skill left the word to his sons, whether he sat in a dīwān or wrote deeds and letters for the people of a market. The name records the calling, and nothing beyond it.

Bearing the name

A family name of this kind records a title, an office or a form of address that was applied to an ancestor and then stayed with his descendants. It is not a lineage in itself, and it confers nothing: no one bearing it today holds an office, a rank, a religious standing or a descent by virtue of the name. It attaches to no tribe, and two families bearing it need have no connection to one another beyond the word itself.
