英文詞源

fail

fail: [13] Fail, fallacy [15], fallible, false, and fault all come ultimately from the same source – the Latin verb fallere. This originally meant ‘deceive’, but it developed semantically to ‘deceive someone’s hopes, disappoint someone’, and in its Vulgar Latin descendant *fallīre this meaning had progressed to ‘be defective, fail’. English acquired the word via Old French faillir. Its Anglo-Norman form, failer, came to be used as a noun, and is the source of English failure [17].

fail (v.)

c. 1200, "be unsuccessful in accomplishing a purpose;" also "cease to exist or to function, come to an end;" early 13c. as "fail in expectation or performance," from Old French falir "be lacking, miss, not succeed; run out, come to an end; err, make a mistake; be dying; let down, disappoint" (11c., Modern French faillir), from Vulgar Latin *fallire, from Latin fallere "to trip, cause to fall;" figuratively "to deceive, trick, dupe, cheat, elude; fail, be lacking or defective."

fail (n.)

late 13c., "failure, deficiency" (as in without fail), from Old French faile "deficiency," from falir (see fail (v.)). The Anglo-French form of the verb, failer, also came to be used as a noun, hence failure.
