  • UK: /ˈɹɛd͡ʒ.ɪ.mən/[1]
  • US: /ˈɹɛd͡ʒ.ɪ.mən/, /ˈɹɛd͡ʒ.ə.mən/[1]

Etymology

It is partly borrowed from Anglo-Norman regimen (“government, administration; medical treatment”) and partly borrowed from Latin regimen (“control, management, guidance”).[2][3][4] The Latin noun is formed from regō (“to rule, direct”) with the suffix -men,[2][5] and in post-classical Latin it also meant a course of medical treatment, and in grammar the relation of a word to the word that governs it.[2] Etymonline traces the verb to Proto-Indo-European *reg- (“to move in a straight line”).[3] The Old French noun is recorded for government from about 1265 and for medical treatment from 1314;[2] the same Latin noun gave régime, the source of regime, and is related to regiment and regent.[2][6][7]

Earliest recorded meaning

A course of diet and way of living kept for the sake of health: before 1400, in a translation of Lanfranc's Science of Cirurgie.[2][4][6] Etymonline dates it to about 1400.[3]

Semantic evolution

The word entered English as a medical term, and the sense "the action of governing" followed in the 15th century; the OED's first example is from Gilbert Hay's Buke of the Law of Armys (1456),[2][3] and that sense is now rare.[2][8] From 1531 grammarians used it for the government of one word by another.[2][7] The extended sense, any systematic course of action adopted for a purpose, is first recorded in Johnson's Rambler in 1751.[2][3] Johnson's dictionary (1755) still defined it only as the care in diet and living that suits a course of medicine.[9] Etymonline notes that regimen, regime and regiment were long confused, and that as late as the late 19th century careful writers used regimen and regime in each other's senses.[3] Since 1797 it has also been used in physical geography for the regime of a river.[2]
