How do you spell say la v in french?

"Say la v" doesn't make sense in French. It's possible you're trying to say something else.

Could you clarify what you want to say?

For example, are you trying to say:

* "S'il vous plaît" (Please)?

* "C'est la vie" (That's life)?

* "La vie" (Life)?

Please provide more context so I can help you accurately translate it into French.
