Gonna, wanna, gotta

Lesson 7

I am going to play.
I am gonna play.
 
I want to play.
I wanna play.
 
I have to play.
I gotta play.
 
When we speak, we very often use gonna, wanna and gotta instead of going to, want to and have to. When we write, it is correct to use going to, want to and have to.
Examples

I’m gonna continues on my journey.
You’re gonna cry.

You can see more examples in the book The Little Prince.
