ethic

Etymology

The noun is inherited from Middle English ethik, also etik,^[2][3] borrowed from Middle French ethique,^[4][2] the title of a study of or treatise on ethics and moral philosophy (Old French etique, about 1245, of a work by Aristotle),^[4][5] and directly borrowed from Latin ēthicē (“moral philosophy, ethics”);^[4][6][7] Latin also had ēthica from the 4th century.^[4][3] These come from Ancient Greek ἠθική (ēthikḗ), the noun use of the feminine of ἠθικός (ēthikós, “moral, showing moral character”),^[4][5][3] short for "ethical philosophy" according to the OED and Etymonline^[4][5] or for "the moral art", with τέχνη (tékhnē, “art”) understood, according to Hoad, Klein and the ODE.^[8][9][6] The Greek adjective is from ἦθος (êthos, “character; in the plural, manners”),^[4][5][7] the source of ethos.^[7] The adjective ethic has the same Middle French source, together with ēthicus (“moral, ethical”).^[4][10][11] Compare Spanish ética and Italian etica.^[4]

Earliest recorded meaning

Moral philosophy, the study of moral principles, and in early use also the title of a treatise on ethics: before 1387, in Trevisa's translation of Higden's Polychronicon.^[4] Etymonline also dates the sense "study of morals" to the late 14th century.^[5]

Semantic evolution

The adjective, "relating to moral principles", followed about 1443, in Pecock,^[4] but Hoad notes that it has mostly been replaced by ethical since the 17th century.^[8] The study itself came to be called by the plural ethics, recorded from the 15th century^[8] and usually construed as singular.^[2] The singular noun took the sense "a system of moral principles" in the 1650s, with a first record in 1659,^[4][5] and later the weaker sense of a set of social or personal values.^[4] From 1760 the adjective was also used, in rhetoric and aesthetics, of ethos as opposed to pathos.^[4]
