Origin
From Middle English temperen, tempren, from Old English ġetemprian, temprian, borrowed from Latin temperō (“(transitive) to divide or proportion duly, to moderate, to regulate; (intransitive) to be moderate, temperate”), from tempus (“time, fit season”). Compare also French tempérer. Doublet of tamper. See temporal.
