Requereixen

Requereixen is the third-person plural present indicative form of the Catalan verb requerir, meaning "they require." The verb denotes a necessity or prerequisite and can govern a direct object or a subordinate clause.

Etymology: Requerir derives from Latin requerere, built from re- (again) and quaerere (to seek or ask). It entered Catalan through historical contact with other Romance languages and evolved into the modern verb form requerir, with requereixen as the corresponding plural present.

Usage: It is used in formal, administrative, legal, and academic language to express prerequisites or obligatory conditions. It is transitive and typically followed by a noun or a clause introduced by que. Examples: "Aquest projecte requereix inversions addicionals." "Les lleis requereixen una avaluació detallada." "Algunes activitats requereixen permisos." In everyday speech, synonyms such as necessitar or exigir may be used, but requieren different nuances: exigir often carries a stronger sense of demand, while necessitar emphasizes need.

Conjugation notes: The infinitive is requerir, and the past participle is requerit. In present indicative, the forms include jo requereixo, tu requereixes, ell requereix, nosaltres requerim, vosaltres requeriu, ells requereixen. Requereixen specifically marks the third-person plural present.
