To say "look" in Spanish, you can use the phrase "luzño" (LOOK-oo). However, there are a few nuances to consider. For example, if you're asking someone to show something to you, it's more accurate to say "léchale" (LEH-chah-leh) or "lúmite" (LOO-mee-tay). On the other hand, if you just want to get someone's attention, a casual "la vista" (LAH-vee-stah) will suffice.
