Negative Informal (Tú) Commands


Negative informal commands, also called negative tú commands are used to tell a friend, family member of the same age or younger, classmate, child, or pet not to do something.

No compres la camisa.
Do not buy the shirt.
No aprendas español.
Do not learn Spanish.
¡No escribas el ensayo!
Do not write the essay!

Always make sure you have a no  or another negative word such as nunca  (never) in front of the verb when forming a negative informal command.

Negative Informal Imperative Forms

The negative informal imperative, yet another term used to describe negative tú commands, is formed differently than the affirmative informal imperative. It is actually formed much like the negative formal imperative in that it uses the present subjunctive form of the verb. Another way to form the negative informal command if you already know your formal commands is to add an -s to the end of the negative formal command.

Irregular Negative Informal Commands

If a verb is irregular in the present subjunctive, it maintains the same irregular form in the negative informal command.

No hagas la tarea.
Don't do the homework.
No seas injusto.
Don't be unfair.

Pronoun Placement

In negative informal commands, the pronoun goes between the negative word (like no or nunca) and the verb.

Nunca les compres dulces a los niños.
Never buy candy for the children.
Nunca se los compres.
Never buy it for them.
