However, it's not typically used in everyday conversation. It's a grammatically correct phrase, but it's not common to use "yes" with a pronoun like "you".
It's likely that you've encountered this phrase in a context where it's used for emphasis or as a way to draw attention to "you" specifically.
To understand the meaning better, you'd need more context. For example:
* "Oui, vous êtes le gagnant!" (Yes, you are the winner!) - Here, "oui vous" emphasizes that the person being addressed is the winner.
* "Oui, vous pouvez me parler." (Yes, you can speak to me.) - Here, "oui vous" emphasizes that the speaker is giving permission to the person addressed to speak.
If you could provide more context about where you saw or heard "oui vous," I could give you a more precise explanation.
