Quaranti

Quaranti is a prefix used in Italian, derived from the number forty (quaranta). It is found in various words and phrases indicating a period of forty days, similar to the Latin-derived "quarantine." The term frequently appears in historical or medical contexts referencing periods of isolation or observation. Specifically, it refers to a period of approximately forty days in length. It is often applied to the observation or isolation of people or goods suspected of carrying a contagious disease.

The word's usage has largely diminished in modern English outside of historical references and literal Italian translations, having been superseded by the more general term "quarantine," which, while etymologically related, doesn't rigidly adhere to the specific forty-day duration.
