Pronunciation
Forms
caput n (genitive capitis); third declension[1] Inscriptions have the spelling kaput, and Catullus and Ovid use an ablative capitī.[2]
Etymology
It is inherited from Proto-Italic *kaput (“head”), inherited from Proto-Indo-European *káput (“head”).[3][1] Cognate with Gothic 𐌷𐌰𐌿𐌱𐌹𐌸 (haubiþ), Old English hēafod and Old High German houbit, all meaning “head”, and with Old Irish cúach (“cup”) and Welsh cawg (“cup”); de Vaan remarks that words for “cup” often come to mean “head”.[3][1] The OLD and Pokorny also compare Sanskrit कपुच्छल (kapúcchala-, “hair at the back of the head”).[2][4] In the compounds anceps, biceps and praeceps the suffix vowel is weakened, while sinciput keeps the u of the simple word.[3]
Earliest recorded meaning
The Twelve Tables (c. 450 BC) use it in the phrase de capite civis, of a citizen's life or civil standing,[2][3][5] and Naevius has the plain sense of the head, covered in mourning.[2][5]
Semantic evolution
Besides the head of a person or animal, it stood for the seat of understanding, for a person's life, and for the life or civil status forfeited by a condemned man, so that capitis damnare meant to condemn to death or exile and capite deminutus described someone stripped of civil rights.[2][6] It also meant an individual, counted “per head” (in capita), and the capite censi were the citizens too poor to be rated by property.[2]
From the body it passed to the top or end of a thing: the summit of a mountain, the head of a boil, a projecting lobe of the liver in divination, the ends of a beam, the mouth or the source of a river, and the starting point of a road.[2] Figuratively it was the origin of anything, a ringleader (scelerum caput in Plautus), the leading person of a state, the capital city, the essential point, the beginning of a speech, a heading, a clause or section of a law, and the principal of a loan as opposed to interest.[2][6]
In medieval Latin it named the opening of a text, the first day of a period (caput ieiunii, Ash Wednesday), the choir of a church, the capital of a province or diocese, the mother house of an abbey and a chief manse.[7][5] Neo-Latin writers used it for a coin bearing a head, the Italian testone.[8] Every Romance language keeps it, from Romanian cap to Italian capo and Old French chief.[9][1] In modern anatomy caput names a head-like protuberance of an organ or bone.[1][10]

Usage notes
Capital punishment was in theory the loss of one's caput, but through most of the Classical period Roman citizens went into exile instead of being executed.[2]
