  • /ɹɪˈfaɪn/[1]

Etymology

It is formed from English re- + fine,[2][3][4][5][6] the obsolete verb fine, to make fine, from the adjective fine in the sense "delicate";[4][7] the prefix is perhaps intensive here.[4][3] Several dictionaries add that it was influenced by French raffiner,[6][8][7][9] formed from re- and affiner,[2] and Skeat calls it coined in English but imitated from the French word.[9] The OED compares Catalan refinar (1575), Spanish refinar, Portuguese refinar (1589), Medieval Latin refinio (“to separate metal from ore”) (about 1295, in a British source) and Middle French refiner (“to refine sugar”) (before 1469), which the French raffiner replaced; it also records an isolated English borrowing of the French verb in 1551.[2] The adjective fine is from Old French fin (“perfected, of the highest quality”).[4]

Earliest recorded meaning

To free from impurities, to purify: about 1572, in Paynell's translation of the Treasurie of Amadis of Fraunce,[2] the year Merriam-Webster also gives.[10] Barnhart dates the verb to 1582, though refined is perhaps implied earlier, in 1574,[3] and Etymonline dates it to the 1580s, of metals.[4]

Semantic evolution

The OED's earliest technical senses are the purifying of metals (1579) and of substances such as sugar (1582);[2] Etymonline dates the sugar sense to the 1610s.[4] Already in the 1580s and 1590s the word was used of language, style, the mind and morals: to polish a language (1582), to clear the spirits from dullness (1589) and to purify morally (1594), all now obsolete.[2][6] The sense of freeing people or manners from coarseness, making them cultured, is recorded from 1592,[2] and Barnhart finds refined in the sense "cultivated, elegant" in Shakespeare's Love's Labour's Lost (1588).[3] The sense of improving a method or product by small changes also dates from 1592, and intransitive refine on or upon, to improve on something by making fine distinctions, from 1659.[2][11] Johnson (1755) gave first the sense of purifying and clearing from dross, quoting the Book of Zechariah.[12] The derivative refinement is recorded from 1611, in Cotgrave, and its senses of elegance, subtlety and improvement in Swift between 1708 and 1710; refinery dates from 1727.[3]
