hi Pedro

wanna= want to

gonna= going to

gotta= got to

And it's the same for "wanna." It's just sloppy/really informal English.

Querer + a = want to = wanna

"I want to stay in bed this morning." = "I wanna stay in bed this morning."

ir+a+infinitive=going to=gonna Por ejemplo "voy a ir a la playa"=I'm going to go the beach=I'm gonna go to the beach.

Bueno en Italiano gonna significa falda jejeje
