How do you say Ross in french?

"Ross" doesn't have a direct translation in French. You'd usually use the original English name, "Ross".

However, if you want to sound more French, you could use a French-sounding name with similar meaning or sound:

* "Roux" which means "red" and could be used if Ross has red hair.

* "Rossignol" which means "nightingale" and sounds similar to Ross.

But ultimately, the best way to say "Ross" in French is simply "Ross".
