jamais
Jamais is a French adverb meaning "never." It is used to express that something did not happen at any time and is the standard negator in negative clauses. In addition to its use in ordinary sentences, jamais can appear in emphatic or exclamatory forms, such as the standalone interjection "Jamais!" meaning "Never!" It also features in fixed expressions such as à jamais (forever) and jamais de la vie (never in my life).
Etymology and history: The word derives from Old French forms such as jamai or ja mais, built
Usage and syntax: Jamais is normally used with the negation ne in standard French: Je ne mange
Cross-linguistic note: Cognates exist in other Romance languages, reflecting Latin iam; equivalents include nunca in Spanish
