This is what they write about Yoda's name on wookipidia
The name Yoda may be derived from 'Yoddha', the Sanskrit word for 'warrior.' The name may also be connected to the Hebrew ???(Pronounced: "Yodea"), meaning "He knows" or "One who knows". Additionally some believe the name might also be a reference to the teachings of Yoga, an ancient eastern mind, body and spiritual practice that influenced many vital energy based martial art forms in the far east, such as Tai Chi, and almost certainly inspired many of the concepts and abilities demonstrated by both light and dark side Force users in Star Wars.
what bugs me about this reasoning is none of the sources actually is YODA it's almost and Like and derived from......
so personally I think my source is more likely to be the true one. ( unfortunately it means that yoda's name doesn't have a cool meaning )
