Affirmative Tú Commands
In Spanish, we use Affirmative Tú Commands (A.T.C.'s) when we want to tell SOMEONE to do
SOMETHING.
A Few Notes To Remember :
1. These are TÚ commands - meaning that they are INFORMAL!
2. We use A.T.C.'s to address only ONE person
3. We can only use an A.T.C. to tell someone to do something - we can't tell someone NOT to do something (yet!).
How to use an Affirmative Tú Command :
Conjugate the verb in the 3rd Person Singular - this is the command! (It's that easy.)
For example : Clean the kitchen.
In Spanish the verb for "to clean" is "limpiar."
All we have to do is conjugate limpiar in the 3rd person singular: "Limpia"
Final Answer : Limpia la cocina.
Now for the 8 Irregular Affirmative Tú Commands:
We use these 8 irregular A.T.C.'s instead of conjugating their verbs in the 3rd person singular. Unfortunately, all you can do is memorize them!
1. Hacer - Haz
2. Decir - Di
3. Poner - Pon
4. Venir - Ven
5. Ir - Ve
6. Ser - Sé
7. Tener- Ten
8. Salir - Sal
Using Affirmative Tú Commands with a Direct Object Pronoun (D.O.P.):
If we want to be more specific with our command, we can use a direct object pronoun. We do it by simply attaching the D.O.P. to the end of the command so that it is all one word!
For Example: Tell me.
The verb in Spanish for "to tell" is "decir" - this happens to be one of our irregulars!
We will write our command: Di

And then we determine our direct object pronoun (in this case, it looks the same although it is pronounced differently!): Me
Final Answer (simply put the two together): Dime. (Pronounced "dee-may")
The Final Note about Affirmative Tú Commands with a Direct Object Pronoun:
If our A.T.C. has a D.O.P., and it is three syllables long or longer, we have to place an accent mark in the command!! Where, you may ask? On the 3rd to last syllable!
For Example: Lets re-write the command "Limpia la cocina" by replacing "la cocina" with its corresponding direct object pronoun, "la"
It becomes: "Limpiala" - now we just have to place our accent mark on the 3rd to last syllable:
Lím-pia-la
3 2 1
Final Answer: Límpiala.
Now you're done!
Acabar + de + Infinitive
We use Acabar+de+infinitive to indicate that someone has JUST done something. To use this phrase appropriately is very simple:
1. Conjugate Acabar based upon the subject of the sentence (WHO just did it)
2. Write the word “de”
3. Write the INFINITIVE (NON-CONJUGATED) form of the verb for the action that was just done.
That’s it!
