"What time do you want to eat breakfast?"
Translation:¿A qué hora quieres desayunar?
Why do we not need "a" before "desayunar" in this sentence? In a prior similar sentence, I left out the "a" and it was counted wrong.
It depends on the word. Ayudar and empezar, for example, require the "a" before an infinitive. Querer does not.
