Inherited from Middle French faillir, from Old French falir, from Vulgar Latin *fallīre, from Latin fallere. See also falloir.
faillir
This verb has two conjugations, one is older and irregular, but is in modern usage giving way to a conjugation like that of finir. It is hardly used except in the infinitive, past historic, and the composed tenses. The third-person singular present indicative faut is also found in certain set phrases.
