✕Common Mistakes
Oi? Está aí?
Using the full form está makes the phrase sound more formal; the casual vibe of Oi? Tá aí? is lost.
Oi? Tá aí??
Doubling the question mark is unnecessary in Portuguese punctuation.
Oi? Tá aí!
An exclamation changes the meaning to “Hey! You’re finally here!” – not a check‑in question.

Cultural Tip
In Brazil, “Oi” has largely replaced the older “Olá” in everyday speech. Adding “Tá aí?” after the greeting signals that you expect an immediate response, so a quick “Tô aqui!” (I’m here!) is the polite reply. The tone should be friendly; a flat or demanding tone can sound rude.
