History
Etymology
Recorded since 1596, from Middle French hypothese, from Late Latin hypothesis, from Ancient Greek ὑπόθεσις (hupóthesis, “base, basis of an argument, supposition”, literally “a placing under”), itself from ὑποτίθημι (hupotíthēmi, “to set before, suggest”), from ὑπό (hupó, “below”) + τίθημι (títhēmi, “to put, place”). Compare hypothec.
