Los Mandatos Informales

Informal Commands or tú/ usted(es)-commands are directed to one ore several persons with whom you are familiar. You use formal commands with
  • friends
  • people who have the same social position or age
  • who you like
  • who you like to be close with, etc.
For formal commands we use tree different verb forms:
  • the third person singular of the present indicative when you tell one person to do something,
  • the second persons singular of the present subjunctive when you are telling one person not to do something,
  • the third person plural of the present subjunctive when you are telling several people to do or not to do something.
If you are not sure, you can also use the verb conjugator .

decir di
hacer haz
ir ve
poner pon
salir sal
ser
tener ten
venir ven

Verbs derived from the above infinitives are also exceptions. Some examples are: desdecir, maldecir, deshacer, suponercomponer, mantener, convenir, etc. Sometimes one or several pronouns (me, te, le, nos, os, les, lo, la) accompany the command form:

Send me the letter. or Send it (the letter) to me.: Mándame la carta. Mándenme la carta. or Mándamela. Mándenmela.

By adding one or two pronouns at the end of the verb you would change the syllable which carries the stress of the word (when a word ends in a vowel, n or s, it's the second syllable from the end that carries the stress), and therefore you have to put an accent on the syllable which had the stress before you added the pronouns, in the case of Mándamela the first a (Manda la carta.).
 
In negative or Don't-do-it-commands the position of the pronoun follows the general rule, which means it stands before the command form:
Don't send me the letter. or Don't send it to me.: No me mandes la carta. No me manden la carta. or No me la mandes. No me la manden.
