Être
Être is the French verb meaning “to be.” It is indispensable and one of the most irregular verbs in the language. It functions as a copular verb, linking the subject with a predicative complement, and as an auxiliary for the formation of compound tenses, notably the passive voice. The verb traces back to Latin esse, through Old French estre; its cognates include Spanish ser/estar and Italian essere.
