Politeness markers and cultural tips
Brazilian Portuguese uses certain words and constructions to sound more polite. These help you come across as respectful and cooperative.

Common mistakes to avoid
Beginners often make a few predictable errors. Watch out for these so your messages sound natural.
Overusing formal verbs in casual contexts can make you sound stiff. For friends, prefer mandar or te explico instead of enviar and overly formal constructions.
Forgetting to specify text or voice can create confusion. If you promise a message, say if it will be an áudio or a typed mensagem.
Not giving a time frame can leave people waiting. Even a vague timeframe like mais tarde helps manage expectations.
Alternative ways to say it with different verbs
Portuguese offers multiple verbs with slightly different tones. Here are alternatives and when to use them.
Esclarecer — to clarify
Use when you want to emphasize clarity and formality: Vou esclarecer por mensagem os pontos pendentes.
Informar — to inform
