How to Say "do it" in Spanish
The most common Spanish word for “do it” is “hazlo” — use this informal command when speaking to someone you know well, like a friend or family member (addressing tú)..
hazlo
/as-lo//ˈaslo/
Examples
Si tienes deberes, hazlo ahora mismo.
If you have homework, do it right now.
Si tienes tarea, hazlo ahora mismo.
If you have homework, do it right now.
No sé si debería llamar. — ¡Claro que sí, hazlo!
I don't know if I should call. — Of course you should, do it!
El plan es arriesgado, pero si crees que funcionará, hazlo.
The plan is risky, but if you think it will work, do it.
Command + 'it' = One Word
'Hazlo' is actually two words combined: 'haz' (the command 'do') and 'lo' ('it'). In Spanish, when you give a positive command and want to add a word like 'it', 'him', or 'her', you attach it directly to the end of the verb.
The Informal 'You' Command
'Hazlo' is the informal way to tell one person to do something. You'd use it with a friend, a family member, or someone your age. It comes from the 'tú' form of the verb 'hacer' (to do/make).
Negative Commands are Different
Mistake: “A common mistake is trying to say 'don't do it' like this: 'No hazlo.'”
Correction: The correct way is 'No lo hagas'. When you make the command negative ('don't...'), the little word 'lo' jumps to the front, and the verb form itself changes.
hágalo
Examples
Si el jefe le pide que lo haga, hágalo inmediatamente.
If the boss asks you to do it, do it immediately.
