Pronunciation

Forms

pur (feminine pure, masculine plural purs, feminine plural pures)[1]

Etymology

It is inherited from Latin pūrus (“spotless, unstained; clean, clear; unmixed”).[2][3][4][5][1][6] The Latin word belonged above all to religious language, like its Greek counterpart Ancient Greek καθαρός (katharós), and goes back to an Indo-European root seen in Sanskrit पूत (pūtá, “purified”).[3][7] A comparison with Old Irish úr (“green, fresh”) remains hypothetical.[3]

Cognate with Romanian pur, Occitan pur, Catalan pur, Italian puro, Spanish puro and Portuguese puro.[7]

Earliest recorded meaning

The Passion de Clermont (late 10th century) uses pura in the abstract sense “complete, unmixed”, of faith.[2][3][8]

Semantic evolution

Wace (about 1130–1155) has it in the moral sense “spotless, chaste”, and in Chrétien de Troyes (1170–1176) it is “unmixed” and “flawless”: vin pur, air pur.[2][8] Pur de “free from” dates from about 1225.[2] Before a noun it means “nothing but”, as in Oresme's pure perece (1370), en pure perte (1509) and pur et simple.[2][3]

Philosophy speaks of état de pure nature (1736), and la Raison pure translates Kant, opposed to practical, science pure and art pur are pursued for their own sake.[3][7] A writer's style is pur in Richelet (1688), and de pure race is in Hugo (1832).[2] In 1721 Montesquieu used un pur for one who professes orthodox doctrine; today pur et dur describes an uncompromising militant.[2][1]
