🗨In Conversation
Você vai ficar quanto tempo?
How long are you going to stay?
Vou ficar uma semana.
I’ll stay for a week.
✕Common Mistakes
Vou ficar de uma semana.
‘de’ is not used to indicate duration with ‘ficar’. Use ‘por’ or omit the preposition.
Vou ficar um semana.
The noun ‘semana’ is feminine, so the article must be ‘uma’, not ‘um’.
Ficarei uma semana.
While ‘ficarei’ (future simple) is grammatically correct, beginners usually prefer the periphrastic future ‘vou ficar’ for spoken Portuguese.
↔Alternatives
Vou permanecer uma semana.
I will remain for a week.
Vou ficar por uma semana.
I will stay for a week.
Vou ficar sete dias.
I will stay seven days.
Cultural Tip
In Brazilian Portuguese it’s common to add the preposition ‘por’ before a time span (e.g., ‘vou ficar por uma semana’), but the preposition can be omitted without sounding odd. Also, ‘ficar’ can mean ‘to become’ in other contexts, so be sure the surrounding words make the staying meaning clear.
