Etymology

It is Middle English afere, borrowed from Anglo-Norman afere, borrowed from Old French afaire (“business, event; rank”) (modern French affaire),[2][3][4] from the phrase à faire (“to do”),[2][3][5] from Latin ad (“to”) and facere (“to do, make”),[2][4] from PIE Proto-Indo-European *dʰeh₁- (“to set, put”).[4] The spelling with one f was remodelled as affaire in Middle French after Latin words in aff-, and Caxton popularized it in England.[2][4]

Earliest recorded meaning

What one has to do, business: about 1300 in the OED and Etymonline,[6][4] probably before 1300 in Barnhart, in the plural aferes, things to do.[2] The OED calls it originally a northern word.[4]

Semantic evolution

Its history runs parallel to that of ado, from Old Norse at “to” and do, and to that of to-do.[7][2][3] The ordinary business of life is from 1484, commercial or professional business from 1519, and public business, the affairs of a nation, from 1605.[6] A thing that concerns someone, as in that's my affair, is from 1611.[6] Vaguely, any proceeding or event, in romance or war, is attested by 1702,[4][6] and of a material thing, as the house was a wooden affair, from 1802.[6] A love affair is from French affaire de cœur, used in English from 1809;[4] to have an affair with someone is by 1726, and earlier to have an affair of love (1716).[4] An affair of honour, a duel, is now archaic.[8]
