Como?

Use Como? when you genuinely need to know the 'how' of something. Did someone explain a process too fast? Como? Did you see something unusual? Como? Did your friend say something confusing? Como? It’s a fantastic way to prompt someone to elaborate or rephrase. It’s also great for asking about someone's well-being, although Tudo bem? is more common for that. You can even use it to express surprise, like 'How did that happen?!'

Como? is wonderfully flexible. In its purest form, it leans towards informal, like when you're texting a buddy or asking a quick question in a casual setting. However, its very simplicity allows it to be used in slightly more formal situations if the context is clear and the tone is right. You wouldn't use it in a super formal speech, but asking a shopkeeper 'How does this work?' with a polite tone is totally fine. It’s the Swiss Army knife of Portuguese questions!

Imagine you're watching a cooking show, and the chef suddenly adds a mystery ingredient. You'd probably lean closer and whisper, Como? Or maybe your friend tells you they finished a marathon in record time – you might exclaim, Como? It's that 'Wait, what?' moment captured in a single word. On an app like Duolingo, this is one of the first question words you'll encounter. Even on Netflix subtitles, you'll see it pop up when a character is confused.

Use Como? when you need to understand the *way* something is done. For example, if someone tells you to abra a porta (open the door) but doesn't specify how, you might ask Como?. It's also great for asking for a repetition or clarification when you missed something. If someone asks you Você entendeu? (Did you understand?) and you didn't, Como? is a polite way to signal you need them to explain again. It’s your default for 'say again?' or 'explain that bit'.

Avoid using Como? as your *only* word when asking about someone's general well-being in a formal setting. While it *can* mean 'how are you?', it's often too abrupt. Stick to Como você está? or Tudo bem? for that. Also, if you're in a very serious, high-stakes meeting, relying solely on Como? might seem a bit too casual. You'd want a more complete sentence to show you're fully engaged. Don't use it when you're asking 'what' – that's O quê?.

Learners often use Como? when they mean 'What?'. Remember, Como? is about the *how*, while O quê? is about the *what*. Another common slip is using it as a full greeting. While it can sometimes imply 'How are things?', it's better to use a fuller phrase like Como vai? or Tudo bem? for greetings. It’s like trying to start a car with just the key fob – you need the whole ignition sequence!

In Portugal, you might hear Como é que é? which is a bit more elaborate but serves a similar function of asking 'How is it?' or 'What's that about?'. In Brazil, especially in informal contexts, you might hear Como assim? which specifically means 'How so?' or 'What do you mean by that?', expressing surprise or disbelief. These variations add color and regional flavor, like different toppings on the same pizza!
