requerem

Requerem is the third-person plural present indicative form of the Portuguese verb requerer, meaning to require or to demand. It is used with plural subjects such as eles, elas, or vocês, and is common in both formal and everyday contexts in Brazilian Portuguese.

Etymology and classification: Requerer comes from Latin requirere, formed with the prefix re- (again, back) and quaerere (to seek). The form requerem reflects standard Portuguese conjugation for the -er verb class in the present indicative for a plural subject.

Usage and meaning: Requerem is a transitive verb, taking a direct object or a complement that specifies what is required. Examples include: "As regras requerem documentação." ("The rules require documentation.") and "Eles requerem mais tempo para a análise." In more complex sentences, the verb can be followed by a subordinate clause introduced by que, where the verb in the clause is in the subjunctive: "Requerem que todos estejam presentes." In such cases, the corresponding present subjunctive form would be requeiram.

Regional and stylistic notes: Requerer is a formal verb often found in legal, administrative, or technical language, though it also appears in general use. In Brazilian Portuguese, the form requerem commonly aligns with the 3rd person plural subject, as in "Eles requerem." In some contexts, synonyms such as exigir or necessitar may be used to convey similar meanings.

Overall, requerem represents a standard, formal means of expressing a requirement or demand by a plural subject in Portuguese.
