Forms

acheter[1] Old French acheder (10th century), achater and acheter (12th century); Anglo-Norman and Picard acater.[2][3][4][5]

Etymology

It is inherited from Old French achater, inherited from Vulgar Latin *accaptō (“to take to oneself; to acquire”), formed from ad- and captō (“to try to seize”) (see capter).[2][6][3][7][1] Some take “*accaptāre” as a remaking of classical Latin acceptō (“to receive”) after “captāre”; others as a compound of “captāre” itself.[8][2][9] It is a doublet of accepter.[1]

Classical Latin used emō (“to buy”), replaced after the 2nd century by comparō (“to procure”), whence Italian comprare and Spanish comprar, “*accaptāre” is behind southern Italian “accattari” and Old Occitan acaptar.[8][2][9] Bloch and Wartburg think Italy may owe the word to northern Gaul, or the reverse.[8] Littré derived it instead from “ad” and “caput” “head”.[5]

Earliest recorded meaning

It is first found in the 10th century as acheder in the Sermon on Jonah.[3][6]

Semantic evolution

The first idea, “to take, obtain”, was overlaid in the middle of the 12th century by that of an exchange for money.[2] Figuratively, as in acheter trop cher sa tranquillité, it has been used since 1160; with a person as object it meant “to win over” at the end of the 12th century, and later “to bribe”.[2][3] Buying something for another, acheter un vélo à son fils, seems recent.[2] Old French also had comperer, from comparāre, in the sense “to pay dearly for”.[8] Derivatives include achat (1178, acat), acheteur and racheter (12th century).[8]
