Pou ki sa ou di "ANNOU ALE" (Let's go) and then "KITE M KONNEN" (Let me know). Why can't you say "ANNOU KONNEN" for LET ME KNOW?

Let us and let me are two different things.  Aren't they?

Let us (Let's) [sort of a command] in Haitian Creole is Annou, Ann, and sometimes Kite nou

1. Let's meet later.
    Annou rankontre pita.

2. Let's help them
    Ann ede yo

3. Let's pray.
   Annou lapriyè.

4. Let's get it done.
    Kite nou fini l.

It is different form Let me (permit me)
