What do va mean?

Answer 1

va is a form of the verb "aller"

je vais, tu vas, il va / elle va / ça va, nous allons, vous allez, ils vont / elles vont

"va" is the form that goes with the pronouns il, elle, ça (he, she, it)

il va à la gare = he's going to the train station

elle va en ville = she's going to town

it can indicate an action in the next future:

elle va s'en aller = she's going to go

il va le faire = he's going to do it

"comment ça va ?" and "comment allez-vous, coment vas-tu?" are common greetings (how do you do?)
