Questions & Answers about Com quem vais ao cinema?
Why does this sentence start with Com quem instead of ending with the word for "with"?
Where is the word for "you" in this sentence?
What exactly does ao mean here?
Ao is a required contraction of the preposition a (to) and the masculine "the" (o). Because cinema is a masculine word, you combine them to say "to the cinema" (ao cinema).
Could I say para o cinema instead of ao cinema?
You could, but it sounds strange for this context. With the verb ir (to go), using the preposition a implies a short, temporary visit, which makes perfect sense for watching a movie. Using para implies a longer, much more permanent stay. For typical everyday outings, always use a.
