[1250–1300; Middle English faute < Anglo-French, Middle French « Latin fallere to be wrong]
syn: fault, foible, weakness, failing, vice refer to human shortcomings or imperfections. fault refers to any ordinary shortcoming; condemnation is not necessarily implied: Of his many faults the greatest is vanity. foible suggests a weak point that is slight and often amusing, manifesting itself in eccentricity rather than in wrongdoing: the foibles of an artist. weakness suggests that a person is unable to control a particular impulse or response, and gives way to it: a weakness for ice cream. failing is particularly applied to humanity at large, suggesting common, often venial, shortcomings: Procrastination is a common failing. vice is the strongest term and designates a habit that is detrimental, immoral, or evil: to succumb to the vice of compulsive gambling.
