I'd like to say "look up", as in "look up at the sky." How do I say this in Spanish'
Thank you for your help! Can you tell me he difference between "vamos" and "vamanos"'
You can say: Ve hacia arriba.
Or: Mira hacia arriba.
Ve is the imperative of "ver" and is kind of a casual look.
Mira, is the imperative of "mirar" and it means that the person will watch.
Or if you just want the person to turn his (her) head up, it would be: Voltea hacia arriba.
