Questions & Answers about Não abro a loja na quinta-feira.
Why do we use na before quinta-feira to say 'on Thursday'?
In Portuguese, to say something happens 'on' a certain day, you use the preposition em (in/on) combined with the word for 'the' (o or a). All days ending in -feira (Monday through Friday) are feminine nouns, so you use em + a, which combines to make the word na.
Do I always have to say the full word quinta-feira?
Not always! In everyday spoken Portuguese, it is very common to drop the -feira and simply say quinta. You could just as easily say Não abro a loja na quinta.
Where is the word for 'I' in this sentence?
How do we make a sentence negative in Portuguese?
It is very simple: just put the word não (no/not) directly in front of the verb. Unlike English, which needs helper verbs like 'do not', Portuguese just uses não abro to mean 'I do not open'.
