mitigation

Etymology

It is inherited from Middle English mitigacioun,^[2][3][4] borrowed from Anglo-Norman mitigacion and Middle French mitigacion, and directly borrowed from Latin mītigātiō (“a soothing; a toning down”).^{[5][4][6][7][3]} The Anglo-Norman noun is recorded from the late 13th century, for the reduction of a penalty or tax;^[8] Etymonline dates it in Anglo-French to the mid-14th century.^[2] In post-classical Latin of the 5th century the word also meant relief of physical suffering.^[5] It is a noun of action from mītigō (“to soften, soothe, make mild”),^[2][3][5] formed from mītis (“mild, gentle, soft”) and agō (“to do, drive”),^[2][3] from Proto-Indo-European *ag- (“to drive”).^[2]

Earliest recorded meaning

Compassion, mercy, favour: before 1382, in the early version of the Wycliffite Bible, a sense now obsolete.^[5] Etymonline gives the late 14th century for "alleviation of sorrow, pain, or anything harsh or severe".^[2]

Semantic evolution

The main sense, the act of making something less severe, painful or harsh, is recorded from about 1400, in a translation of Lanfranc's surgery.^[5] Lydgate used it, probably, for a soothing remedy (?1435).^[5] From 1588 to 1895 it could mean the softening or qualifying of words.^[5][4] From 1622, in Bacon, a mitigation was also something that lessens severity, and later, in criminal law, the mitigating circumstances of a case as a whole.^[5] Johnson (1755) defined it as the "abatement of any thing penal, harsh, or painful".^[9] A 1737 translation of Josephus used it for the taming of an animal.^[5]
