Requer-se que

You use requer-se que followed by a verb in the subjunctive mood. This is crucial! The subjunctive is used for uncertainty, desire, or necessity, which fits perfectly here. For example, Requer-se que os alunos estudem (It is required that students study). You’ll see it in formal documents, instructions, and official notices. It’s a way to state a requirement clearly and impersonally. It’s like saying the universe demands this action!

This phrase leans heavily towards formal and official settings. Think legal documents, academic papers, company handbooks, or government regulations. You wouldn't typically use it in a casual chat with friends unless you were joking about a strict rule. It sounds quite serious and authoritative. Using it in a very informal context might make you sound like you're quoting a rulebook, which can be funny or just plain weird.

Imagine a website's terms and conditions: Requer-se que o usuário aceite os termos. (It is required that the user accepts the terms.) Or a health and safety notice: Requer-se que todos usem capacete. (It is required that everyone wears a helmet.) It’s also common in job postings: Requer-se que os candidatos tenham experiência prévia. (Previous experience is required from candidates.) Even in academic settings, like a university's rules: Requer-se que os trabalhos sejam entregues até sexta-feira. (Assignments are required to be submitted by Friday.)

Use requer-se que when you need to state a non-negotiable requirement in a formal or official context. It's perfect for official announcements, rules, laws, contracts, or academic policies. Think about situations where clarity and authority are key, but you don't need to specify *who* is imposing the rule. It’s the voice of the regulation itself! It’s also great when you want to sound extra professional or perhaps a little bit intimidating (in a good way, like a strict but fair teacher).

Avoid requer-se que in casual conversations with friends, family, or colleagues unless you're being deliberately humorous. It sounds too stiff and formal for everyday chat. Don't use it for simple suggestions or personal preferences. If you're just asking a friend to bring snacks to a party, you wouldn't say, Requer-se que tragas os salgadinhos. You'd say, Traz os salgadinhos, por favor! It's also not the best choice for expressing a personal need; Eu preciso de ajuda (I need help) is much more direct.

One common slip-up is forgetting the subjunctive mood after que. For instance, saying Requer-se que os clientes pagam is incorrect. The verb should be in the subjunctive. Another mistake is using it too informally, making your speech sound unnaturally stiff. It’s like wearing a tuxedo to a beach party – technically clothing, but not quite right!

While requer-se que is standard, you might sometimes see variations like é necessário que (it is necessary that) or é preciso que (it is necessary that), which are slightly less formal but convey a similar meaning. In very informal spoken Portuguese, people might just say tem que (has to), which is much more direct and casual. Regional differences are subtle here; the core meaning remains, but the frequency of use might vary. Think of requer-se que as the formal cousin of precisa-se que.
