buckle

Etymology

It is inherited from Middle English bukel, later bokel,^[2] borrowed from Old French bocle (“boss of a shield; buckle, metal ring”), also bucle and Anglo-Norman bucle,^[2][3][4][5] now French boucle.^[3][6][7] The French word comes from Latin buccula (“cheek strap of a helmet”), in Late Latin also the boss of a shield,^[3][6][8] a diminutive of bucca (“cheek”).^{[8][9][10][4]} Merriam-Webster explains the French sense: the boss of a shield bulges slightly from its face, rather like a small cheek, and the word was later extended to the fasteners of belts.^[11] The OED finds the relation between the Latin and the French senses obscure.^[8] Ayto notes that some have linked bucca with pock.^[10][12] The verb was formed from the noun in the late 14th century, as bokelen.^[3][2][4] Its sense "to bend out of shape" is traced by Etymonline, the Shorter Oxford, Hoad and the ODE to Middle French boucler (“to bulge”), itself from bocle,^[3][4][6][5] and Barnhart suggests it may have been borrowed again from French;^[2] the OED treats it as possibly from the French verb, which is used of a wall bulging.^[8] Weekley instead connected the "bend" sense with Dutch buigen (“to bend”) and German Buckel (“hump”), cognate with bow.^[13]

Earliest recorded meaning

A metal clasp with a spiked tongue for fastening a belt or strap: Barnhart and Etymonline date it about 1300,^[2][3] and Merriam-Webster finds it in the poem “Most i ryden” (about 1325), describing a girdle whose buckle was of whalebone.^[11] The OED's first quotation is from the Ayenbite of Inwyt (1340),^[8] where chastity is called the buckle of the girdle.^[11]

Semantic evolution

Chaucer used the noun and the participle bokelynge once each.^[14][2] The verb, at first "to fasten with a buckle" (about 1400 in the OED),^[8] took on the sense "to prepare oneself for action" in the 16th century, probably a metaphor from buckling on armour before a battle;^[3][8] from this came buckle to (1712) and buckle down, originally American, "to set to work vigorously".^[8][4] Weekley compared to gird up one's loins.^[13] From 1535 buckle also meant to come to close quarters or grapple with an opponent, a sense now dialectal.^[8][4] From the late 17th century it meant to marry, humorously or in dialect;^[8][4] Green's Dictionary of Slang has it in this sense from 1594, in Lyly.^[15] In the 18th century a buckle was also a curl of hair, and to buckle hair was to keep it in curl, both now obsolete.^[8][4] The sense "to bend out of shape or crumple, especially under pressure" appears about 1525,^[2][4] in the 1520s as "to arch the body" in Etymonline;^[3] it was used of giving way under strong pressure from the 1590s,^[3] and the noun buckle, a kink or bend produced by buckling, is dated by Merriam-Webster from 1876.^[12] In North America a buckle is also a cake with fruit, typically blueberries, and a crumbly topping, recorded from 1935.^[8][12]
