Question 4

How do you form negative tú commands?

First, drop the -o from the yo form of a regular verb in the present tense. If the verb is -ar, add -es to the end, while if the verb is -er or -ir, add -as to the end.

hablar -> hablo -> no hables
guardar -> guardo -> no guardes
prender -> prendo -> no prendas
volver -> volvo -> no volvas
pedir -> pido -> no pidas
