Forms

cento m or f[1] Old Galician-Portuguese wrote cento (1272) and çento;[2] çiento is recorded in 1275 and çeto in the 14th century.[3][2]

Etymology

It is inherited from Latin centum (“hundred”), written Old Galician-Portuguese cento in the oldest texts.[3][1][4] cem is a shortened form of the same word, from its use before a noun.[5][2] In the medieval language the short and the full form were used without distinction, and Michaëlis noted that the full form was still used as an adjective until the end of the 15th century.[5][6] Today the full form is used only before lower numbers.[5]

The same Latin word is Galician cento, Spanish ciento, Catalan cent, French cent and Italian cento.[7][8][1] The Spanish shortened form is cien.[9]

The Latin word comes directly from Proto-Indo-European, through Proto-Italic *kəntom, from *ḱm̥tóm.[1][10] De Vaan writes it *dḱmtom and lists among its cognates cét, शत (śatá), ἑκατόν (hekatón), šim̃tas and 𐌷𐌿𐌽𐌳 (hund).[10]

Earliest recorded meaning

Houaiss dates the word to 1272, from Cunha's index of medieval Portuguese, and Cunha puts it in the 13th century.[3][2] The Cantigas de Santa Maria use it on its own, as in non podian achar ontr'outras mais de cento “they could not find more than a hundred among the others”, and a cantiga of King Denis says moran ben cento naquela rua “a good hundred live in that street”.[6]

Semantic evolution

Bluteau (1712) still equates cento with cem and gives um cento de moedas de ouro “a hundred gold coins”, aos centos “by the hundred”, and the card game centos.[11] He also lists proverbs such as Quem faz um cesto, fará cento “who makes one basket will make a hundred”.[11] Morais (1813) describes counting noventa e nove, cem, cento e um, and the poetic cento e cento “in great numbers”, which Vieira and Aulete illustrate from Camões.[12][13][14]

In the modern language cento is the form of the numeral before lower numbers, the form in por cento “per cent”, and a noun “a set of a hundred”, used in counting fruit, eggs and the like.[3][15][14]
