Caput, a Latin word meaning literally "head" and by metonymy "top", has been borrowed in a variety of English words, including capital, captain, and decapitate. The surname Caputo, common in the Campania region of Italy, comes from the appellation used by some Roman military generals. A variant form has surfaced more recently in the title Capo (or Caporegime), the head of La Cosa Nostra. The French language converted 'caput' into chief, chef, and chapitre, later borrowed in English as chapter.
Caput baroniae is the seat of an English feudal barony. Caput baronium is the seat of a barony in Scotland.[a] The central settlement in an Anglo-Saxon multiple estate was called a caput, short for caput baroniae.
Caput is used in medicine to describe any head like protuberance on an organ or structure, such as the caput humeri.
The German word kaputt ("destroyed"), from which derives the English colloquialism 'kaput' or 'caput,' meaning done, or finished, is not related to this word. The origin of the German word, and consequently the English words, is a borrowing from the French: être capot, lit. 'to be bonnet' or fig. 'to be defeated'.
