Question: gawain how do you say it?
Answer: The American Heritage Dictionary has four different pronunciations listed (gə-w”n', gä'w”n', gou'ən, gä'wən), and a lot of other sources seem to have multiple pronunciations as well. I have no idea which one is right, but I think, if I saw the name on paper, I'd most likely pronounce it as GAH-win.
