✕Common Mistakes
Confirme até sexta-feira, por favor.
‘Confirme’ is the formal imperative; using it with ‘por favor’ in a casual chat can sound overly stiff.
Confirma até sexta, por favor.
Dropping ‘‑feira’ is fine in spoken language, but in written professional contexts the full day name is preferred.
Por favor, confirma até sexta-feira.
Placing ‘por favor’ before the verb is acceptable, but the most natural order in Portuguese is verb‑first, then ‘por favor’.

Cultural Tip
In Brazil, adding ‘por favor’ at the end of a request is common and softens the tone. If you’re writing to a superior or a client, switch to the formal imperative ‘confirme’ and consider using ‘por gentileza’ for extra courtesy. Also, many Brazilians shorten ‘sexta‑feira’ to ‘sexta’ in informal speech.
