Word History

Etymology

Noun

Middle English tempure, tempyr, temper "moderation, mixture of things in proper proportion, mental state," probably noun derivative of tempren, temperen "to mix with, soften, moderate" — more at temper entry 2

Verb

Middle English tempren, temperen "to be mixed with, mix with, soften, moderate, regulate, tune," in part going back to Old English temprian "to mix with, moderate," borrowed from Latin temperāre "to exercise moderation, restrain oneself, moderate, bring to a proper strength or consistency by mixing, maintain in a state of balance," perhaps derivative of temper-, variant stem of tempor-, tempus "period of time"; in part borrowed from Anglo-French temprer, tremper, going back to Latin temperāre — more at tempo

Note: The derivation of temperāre from temper- and hence tempus is based on the hypothesis that the original meaning of the noun was "extent, measure"; however, it is not entirely certain that the meanings "to restrain" or "to bring to a suitable state by mixing" (whichever might be the original meaning of temperāre) are consonant with the idea of measuring.
