Forming negative commands with reflexive verbs (L'Impératif)

Look at these negative commands (negative imperatives) that use reflexive verbs:

Ne t'assieds pas !  Don't sit down!

Ne nous asseyons pas ! Let's not sit down!

Ne vous asseyez pas ! Don't sit down!

When forbidding (negative orders) using reflexive verbs, you keep the regular order of the words in a negative statement and simply drop the subject pronoun tu/vous/nous.
Tu ne t'assieds pas -> (X) Ne t'assieds pas!

Look at these other examples:

Ne t'habille pas!Don't get dressed!

Ne te couche pas !Don't go to bed!

Ne te lève pas !Don't get up!

Remember that for -er verbs, you lose the -s in the tu form.
