"je vais m'arrêter de parler"
Vous allez vous arrêter de parler.
quand allez-vous l'arrêter?
You can say "Je parle" which means "I am speaking" in French.
That's an odd usage but the gist is" Stop speaking French".
No, it's not correct. You shall say: It's French speaking. For example, you can say: Quebec, it's a French speaking area/region/province.
I am assuming you want to say "Yes, I am speaking French" in French. In that case, it would be: Oui, je parle français.
English speaking Canadians say "Easter" French speaking Canadians say "Pâques"
Stop it! is 'arrête !' or 'arrête ça !' in French.
"Stop" in French is "arrêt" or "stop."
Je parle en français.
In French, you would say "your grandmother" as "ta grand-mère" if you are speaking informally, and as "votre grand-mère" if you are speaking formally.
Ca man ca vas - That's how you say (How is it going) in french.
