Etymology

It is inherited from Middle English failen,[2][3] borrowed from Old French faillir (“to be lacking, miss, not succeed; to run out; to err; to let down”), falir,[4][2] from Vulgar Latin *fallīre,[2][3] an alteration of Latin fallere (“to trip, cause to fall; to deceive, cheat; to be lacking or defective”).[4][2][5] De Vaan traces fallere to a root meaning “to stumble”, compare Sanskrit skhalate “stumbles, fails” and Greek sphállein “to throw down”, so that “deceive” would be a metaphor from “stumble”.[4] It replaced Old English ābrēoþan.[4] The noun, as in without fail, is from Old French faille.[2][6] It is related to false, fault and failure.[2][7]

Earliest recorded meaning

“To be unsuccessful; to cease to exist or function, come to an end”: probably before 1200, in the Ancrene Riwle,[2] about 1200 in Etymonline.[4]

Semantic evolution

“To fail in expectation or performance” is from the early 13th century.[4] Of supplies of food or goods, “to run short”, it is from the mid-13th century,[4] and of crops and of strength or courage, “to grow feeble”, from about 1300.[4] Of material objects, “to break down”, it is from the late 14th century.[4] The noun, without fail, is from about 1275,[2] 1297 in the OED.[8] The academic fail, a grade below the pass mark, is from 1944.[8] Failure is from 1660, replacing failer (1643), an Anglicized law-French word.[2] In Scotland, a fail was also a sod of turf, of unknown origin.[9][8]
