French Verbs in the imperative mood: to Command

There are as many people who like to give orders as few people who like to obey them.
The imperative mood uses only 3 persons: tu, nous, vous.
All -er verbs make the imperative by dropping the pronoun before the verb conjugated in the present.
The "tu" person is written without the final "s".
Rester: reste, restons, restez.

There are 2 basic patterns: either the verb is alone, or the verb comes with a complement.
Each structure can be affirmative or negative.

Verb	Complement
Tiens!
Ne venez pas!
Dis	la vérité!
N'achetons pas	les tomates!

An indirect object that is fully expressed has to be added at the end of the sentence:

Verb	Direct object article+noun	Indirect object preposition+article+noun
Ne viens pas		chez Mamie!
Achète	les tomates	au (= à le) supermarché!

But when the indirect object is replaced with a pronoun, it comes before the other complement(s):

Verb	Pronoun	an object	another object
Dis-	moi	la vérité!
Achète-	leur	du chocolat	au supermarché!
