the.com/fail

means To not succeed at something you attempted — to fall short of a goal, standard, or expectation.

from From Old French 'faillir,' tracing back to Latin 'fallere,' meaning 'to deceive' or 'to trip up.' The sense shift is telling: a failure originally felt like being tricked by circumstance, not simply falling short through one's own doing. That same Latin root 'fallere' also gives English 'fault' and 'false' — a small family of words all built around the idea of something going wrong or someone being misled.
