adj. accepted as true or as certain to happen, without proof

The word assumed traces back to Latin assumere ("to take up, adopt"), combining ad- (toward) and sumere (to take). It entered Middle English via Old French assumer, initially meaning "to take up or adopt a role." Over time, it expanded to include the sense of "accepting something as true without proof," reflecting the idea of "taking on" an idea or identity.
