Hello! I've been studying the Haitian Creole language and I really like this language and it's fantastic that I can talk to Haitian friends in their mother tongue. I want to know the difference between PRAL and VA (or, A).

That is awesome :)

Va, a, or ava – future tense – aux: will or shall

Nou va kite demen.

N’a kite demen

N’ava kite demen.

We will leave tomorrow.

We shall leave tomorrow.

Pral, prale – to be + going to

M pral pale avè l pou m ka fè l konnen sa m peze.

Or 

M prale pale avè l pou m ka fè l konnen sa m peze.

I’m going to talk to her to let her know what I’m made of.
