Questions & Answers about Podes fumar na rua.
Why is the word 'you' missing from the sentence?
How do we use 'poder' (can) with another verb like 'fumar' (to smoke)?
When you want to say you 'can' do something, you change the verb poder to match the person (here, podes for 'you'), and leave the second verb in its original dictionary form, called the infinitive (here, fumar). You do not need any linking words between them.
Why does it say 'na rua' instead of 'em a rua' for 'in the street'?
Na is a mandatory combination (contraction) of the preposition em (in/on) and the feminine word for 'the' (a). Because rua (street) is feminine, 'in the street' merges em + a to make na rua.
