Questions & Answers about ¿Vas a comprar los billetes el próximo lunes?
How does vas a comprar translate to 'are you going to buy'?
This sentence uses the structure ir (to go) + a + an infinitive (the basic, unconjugated form of a verb). It works almost exactly like 'going to' in English to talk about future plans. Here, vas means 'you go', a means 'to', and comprar means 'buy'. Together, vas a comprar translates to 'you are going to buy'.
Where are the words for 'are' and 'you' in this question?
In Spanish, the 'you' is already built into the verb vas (the 'tú' form of the verb ir). Because the verb ending tells us who the subject is, the pronoun tú can be dropped. Also, Spanish doesn't use helper words like 'do' or 'are' to make questions. You simply take the statement 'you are going to buy' (vas a comprar) and ask it with a questioning tone!
I've heard entradas used for 'tickets'. Why does this sentence use billetes?
It depends on what the tickets are for! In Spain, billetes is typically used for transport, such as train, bus, or plane tickets. If you were buying tickets for an event, like the cinema, a concert, or a museum, you would use the word entradas.
