Origin: 1350–1400; aphetic variant of Middle English acloyen < Middle French enclo(y)er < Late Latin inclāvāre to nail in, equivalent to in-in-2 + -clāvāre, verbal derivative of clāvus nail
to make weary or cause weariness through an excess of something initially pleasurable or sweet
[C14 (originally: to nail, hence, to obstruct): from earlier acloyen, from Old French encloer, from Medieval Latin inclavāre, from Latin clāvāre to nail, from clāvus a nail]
1530, aphetic of Anglo-Norm. acloyer, from O.Fr. enclouer "to fasten with a nail, hinder, cripple a horse by driving a nail into the hoof," from clou "a nail," from V.L. inclavare, from L. clavus "a nail" (see slot (2)). Meaning "to fill to loathing, surfeit" is first recorded 1530.
