What does James mean in ancient Greek?

Answer 1

James. James is an English name, therefore it does not change spelling when written in another language. It goes for all names - if, for example, you had a Greek pen-pal, you would write their name the right way (the Greek way) even if your letter was in English.

Answer 2

James in Greek is Yakavos, which in turn in Doric Greek means 'calm of the sea'.
