- presumption
- early 13c., "seizure and occupation without right," also "taking upon oneself more than is warranted," from L.L. praesumptionem "confidence, audacity," in classical L., "a taking for granted, anticipation," from praesumere "to take beforehand," from prae "before" + sumere "to take." In English, the meaning "the taking of something for granted" is attested from c.1300. Presumptuous preserves the original sense.
