ラテン語のquadraginta「四十」から、quadr-「四」、-gin「十」、語源はten「学部長」と同じ。 現在の意味は、17世紀にイタリアのヴェニスの港がペストの侵入を防ぐために、ペスト発生地域からやってくる商品や物品に課した40日間の検疫に由来する。

quarantine

quarantine: [17] Quarantine denotes etymologically a period of ‘forty’ days. It goes back ultimately to Latin quadrāgintā ‘forty’, whose Italian descendant quaranta formed the basis of the noun quarantina ‘period of forty days’. English used it originally for a ‘period of forty days’ isolation’, but gradually the stipulation of the number of days faded out.
