Forms

quarantaine f (plural quarantaines)[1] Old French quaranteine.[2][3] Anglo-Norman spellings include karanteine, quarenteine and quarantine.[4]

Etymology

It is formed from French quarante + -aine.[5][2][6][1] Quarante comes from Vulgar Latin quaranta, the popular form found in inscriptions from Gaul, for classical quadrāgintā (“forty”).[6] Wiktionary takes the medical sense, isolation against contagion, as a calque of Italian quarantena.[1]

Cognate with Occitan quarantena and Spanish cuarentena.[3]

Earliest recorded meaning

The TLFi's first record is in Guernes de Pont-Sainte-Maxence's life of Thomas Becket (about 1174–76), meaning “a number of forty”;[5] Littré quotes it: E quant la quaranteine des meis fust trespassée “and when the forty months had passed”.[3] The Anglo-Norman Dictionary has records from as early as 1121–25.[4]

Semantic evolution

From the number, the word soon came to mean a period of forty days (1180–90), and in particular Lent, the forty days of fasting (about 1200).[5][7] In feudal law, the quarantaine du roi was the forty days set by Louis IX during which an offended man could not take revenge.[3] Anglo-Norman also used it for a furlong and a square measure of land.[4]

The sense that dominates today, the isolation of up to forty days imposed on travellers coming from a place struck by a contagious disease, is recorded in 1635.[5][7] It gave the figurative mettre en quarantaine, to shut someone out of a group, recorded from 1772.[7] Since Furetière (1690) it has also meant an age of about forty.[7]
