Mastering Register Shifts (Tu, Você, O Senhor)

• Tu: The true second-person singular. It is the standard for informal relationships (friends, family) in Portugal and in specific regions of Brazil (like Rio Grande do Sul and parts of the Northeast).
• Você: A second-person address that is grammatically third-person. In Brazil, it has become the neutral, all-purpose default, used with everyone from close friends to shopkeepers. In Portugal, its use is more restricted and can be perceived as overly direct or even rude when used with strangers.
• O senhor / A senhora: This is the next step up in formality. Literally "the gentleman / the lady," it functions as a formal you, also taking a third-person verb. It explicitly signals respect, hierarchy, or a significant age gap.

• Indicative Mood: Direct and assertive. This is the baseline for low-register, high-certainty communication. Preciso da sua ajuda. (I need your help.)
• Conditional Mood: Softens a request by placing it in a hypothetical space. This is a standard tool for formal politeness. Gostaria de falar com o diretor. (I would like to speak with the director.)
• Imperfect Subjunctive Mood: The most deferential and formal option. It creates maximum distance and is often used in expressions of wishing or in highly polite requests. Quisera saber se o relatório já foi concluído. (I should like to know if the report is finished yet.) It is often combined with se clauses: Agradeceria se pudesse me enviar o arquivo. (I would appreciate it if you could send me the file.)

• Clitic Placement (Pronoun Placement): In Brazil's spoken language, proclisis (pronoun before the verb), as in ele me disse, is the unmarked default. In formal written BP and nearly all contexts in EP, enclisis (pronoun after the verb), as in ele disse-me, is the standard. Starting a sentence with a clitic (Me disseram que...) is common in informal BP but is a significant error in formal writing. A third, hyper-formal option, mesoclisis (pronoun inside the future or conditional verb), like dir-lhe-ei (I will tell you), exists but is now confined mostly to legal texts and very solemn speeches.
• Passive Voice: The active voice (Nós resolvemos o problema) is personal and direct. To increase formal distance, you can use the passive voice. The analytic passive (O problema foi resolvido por nós) is common. For peak formality and impersonality, the synthetic passive with se (Resolveu-se o problema) is preferred, as it completely removes the agent.

When in doubt, err on the side of formality. It is much easier and more socially acceptable to be invited to a lower, more informal register (Pode me tratar por você) than it is to recover from being perceived as rude or overly familiar. This is especially true in Portugal.

In Brazil, você is almost always the safe starting point. As you get to know the person, you can listen to how they address you and how they talk to their own friends. If they and their social circle use tu, you can begin to mirror them. Outside of the tu-dominant regions, você is often used even between very close friends.

No. A gente is strictly for informal, spoken contexts or their written equivalents (texting, social media). In any form of professional or academic writing, nós is the only correct first-person plural pronoun. Using a gente immediately marks the text as non-professional.

These are specific pronomes de tratamento for high-ranking officials and professionals (e.g., Vossa Excelência for presidents and ambassadors; Vossa Magnificência for university rectors). Like o senhor, they take third-person verbs. You need to be able to recognize them, but you will almost never use them unless your profession is in law, diplomacy, or high-level government administration. The key distinction is using Vossa when speaking to the person and Sua when speaking about them.
