Forms

raison f (plural raisons)[1]

Etymology

It is inherited from Old French raison, inherited from Latin ratiō (“reckoning, account; reason”) (accusative “ratiōnem”).[2][3][4][5][1] The Latin noun is from “ratum”, the supine of reor (“to reckon, think”), itself old and of unknown origin.[3][6] “Ratio” first meant “account, calculation”, then the faculty of reckoning and reasoning, and in philosophy it translated Ancient Greek λόγος (lógos), which meant both “account” and “reason”.[3][4]

Cicero used it for the argument that justifies an action, whence Medieval Latin “dispute, discussion” (about 600) and Old French “speech, discourse”.[4][3] Its learned doublet is ration.[1][3] Cognate with Italian ragione, Occitan rason, Spanish razón and Portuguese razão.[7][8]

Earliest recorded meaning

About 980 the Passion of Clermont opens with vera raizun, “a true account”, in the sense “speech, story”; the same text has de raizon “rightly”.[2][9]

Semantic evolution

By the 12th century the word had most of the senses of Latin ratio.[3] The sense “what is right, just” gave est raison que “it is right that” (about 1130) and avoir raison (about 1180), as opposed to tort.[2][3] About 1170 it named the faculty of judging well and the discursive intellect, as in Chrétien de Troyes.[2] The sense “account, reckoning” survived in the livre de raison, a household account book, until the 16th century.[4][3]

Raison “cause, motive” is found about 1112.[2] Bloch and Wartburg note that the Middle Ages confused Cicero's distinction between ratio, the reason one gives, and causa, the real cause; the borrowing of cause at the Renaissance restored it.[4][3] Later phrases include âge de raison (1690), mariage de raison (1826) and raison pure from Kant (1810).[2]
