rápida resposta

You can use it as a noun phrase. Usually, you pair it with the verb ter (to have). For example, "Você teve uma rápida resposta." You can also use it to thank someone. Just say, "Obrigado pela rápida resposta." It works for emails, texts, or even verbal answers. It is simple, clean, and very effective.

Use it in the office when a colleague emails back. Use it when a friend replies to your dinner invite. It is perfect for customer service situations. If a waiter brings your drink fast, you can mention it. It is a great way to show appreciation. It makes the other person feel like a pro.

Don't use it for physical speed. If a car is fast, don't use this. That would be carro rápido. This phrase is specifically about communication or solutions. Also, avoid it if the answer was fast but wrong. It implies quality and speed together. Using it sarcastically might come off as a bit rude.
