‘Adeus’ is more formal and can sound overly solemn in casual conversation; use ‘tchau’ instead.
Tchauu, até logo!
Adding extra vowels is a spelling error; the correct spelling is ‘tchau’.
Pronounce ‘tchau’ like the English word ‘chow’.
The English diphthong /aʊ/ is not used in Portuguese; the correct pronunciation is /tʃaw/.

Cultural Tip
In Brazil, ‘tchau’ is the default goodbye in almost every region. ‘Adeus’ is rarely used in daily life because it can sound final or solemn, reserved for farewells that may be long‑lasting (e.g., moving away). In Portugal, you’ll also hear ‘tchau’, but ‘adeus’ is a bit more common in formal settings. When waving goodbye, Brazilians often add a hand wave or a kiss on the cheek with close friends, while ‘tchau’ itself stays the same.
