requérir

Requérir is a French verb meaning to require, to demand, or to requisition. In modern use it often expresses necessity or prerequisites, as in “Cette tâche requiert de l’expérience.” It can also mean to call for or to summon, particularly in formal or legal contexts, and to requisition resources or personnel, such as “requis des preuves” or “réquisition des vivres.” In everyday speech, more common verbs are exiger or avoir besoin de.

Etymology and sense: The verb comes from Old French requérir, itself from Latin requirere “to seek again, to search for.” The sense evolution covers both needing something and summoning or calling for aid or resources.

Conjugation and usage notes: Requérir is a regular -ir verb in its conjugation, with some orthographic accents in the present and other tenses. Present indicative: je requiers, tu requiers, il requiert, nous requérons, vous requérez, ils requièrent. Imperfect: je requérais, tu requérais, il requérait, nous requérions, vous requériez, ils requéraient. Past participle: requis (masc.), requise (fem.). Compound tenses use avoir: j’ai requis, il a requis. Future: je requérirai, tu requéreras, il requérira, nous requérirons, vous requérerez, ils requériront. Subjunctive present: que je requière, que tu requières, qu’il requière, que nous requérions, que vous requériez, qu’ils requièrent. The verb also appears in literary passé simple as requirí, requirá, but the compound past (passé composé) with avoir is standard in contemporary usage.

Notes: The verb remains somewhat formal or legal; in common prose you will often find exiger or nécessiter as alternatives.
