Bonjour

1- The imperative tense is mainly  used to give orders, (make a request, give advices, express something you want as a desire, recommend something ...all kinds of commands ...)

2-  "tu" form = 2nd person singular : informal "you" (for a friend, s.o. you know well)

3- "vous" form = 2nd person plural (several persons) OR formal you ('vous de politesse' for s.o. older, for s.o. you don't know ...)

4- "nous" form = 1st person plural   ==> "let's"

5- verbs in -er = -e / -ons / -ez  (1er groupe =  speak : parler : parle / parlons / parlez  // sing : chanter :  chante / chantons / chantez )

  aller               = va  /allons / allez (irregular verb)

    verbs in -ir  = -e  / -ons       / -ez        (ouvrir = 3 ème goupe > ouvre / ouvrons / ouvrez)

so, as you can see, verbs in -ir as 'ouvrir' (3 ème goupe) and those in -er ( 1er groupe as 'chanter') have the same endings

'aller' is an irregular verb.

  [But the verbs in -ir  = -is / -issons  / -issez   (finir  = 2 ème groupe >finis / finissons  / finissez) are diffferent]

6- "avoir"

   aie   / ayons  /      ayez

  "être"

   sois  /   soyons   /soyez

7- Translate

a- (to a child)  Brush your teeth !  = Brosse-toi les dents !

b- (to a group of people) Listen to the teacher ! = Écoutez le professeur !

c- (to a group including yourself) Let's go to the movies ! = Allons au cinéma !

d- (to a child) Do your homework ! = Fais tes devoirs !

e- (to a group of people) Don't take the medicine ! = Ne prenez pas le(s) médicament(s) !

f- (to a group including yourself) Let's not suffer ! = Ne souffrons pas !

hope this helps ☺☺☺
