requirere

Requirere is a Latin verb meaning to seek again, to look for, to require, or to demand. In classical Latin it covers both literal searching and figurative asking for something as a duty or necessity.

Etymology and relation: The verb is formed from the prefix re- attached to quaerere, the core verb meaning to seek. It belongs to the quaero family of verbs and is typically treated as a third-conjugation verb in grammars.

Usage and syntax: Requirere governs a direct object in the accusative for the thing sought or required (requirere aliquid). It can express a request or demand and may appear with ut followed by the subjunctive to denote that someone should do something (for example, requiro ut veniat). In compound tenses it forms the standard perfect, pluperfect, and future of the third-conjugation pattern. The passive participle is requisitus (or requisitum), used in attributive or periphrastic constructions.

Derivatives and related forms: The participle requisitus yields adjectives meaning “required” and, in certain contexts, related nouns such as requisitio, indicating a requirement or demand, though the latter is relatively uncommon in Classical Latin.

See also: quaero; requiro; requisitus; requisitio.
