The short answer
Como assim? often means “How so?” or “What do you mean?” It signals that you want the speaker to explain a detail, clarify a surprising statement, or give an example. Tone matters: with a curious voice it is a natural request for clarification; a sharp tone can sound impatient.
Use como assim? when you need more context
You can repeat the key information after the phrase to show exactly what confused you. A short follow-up keeps the conversation moving and makes the request clearer.
Como assim, o restaurante fechou?
What do you mean, the restaurant closed?
Como assim você vai embora hoje?
How so—you’re leaving today?
Como assim? Pode explicar melhor?
What do you mean? Could you explain a little more?
Ask a more specific follow-up if needed
Como assim? is useful in casual conversation, but a specific question can help when you need practical information. Ask what changed, when something happened, or which detail the other person means.
Como assim o horário mudou? Qual é o novo horário?
What do you mean the time changed? What is the new time?
Como assim não tem ingresso? Acabou hoje?
What do you mean there are no tickets? Did they sell out today?
Put it into practice
Use como assim? to invite an explanation, then add a focused follow-up question. A curious tone makes the phrase sound open rather than confrontational.
