I am arguing with some douchebag at my school on the spelling of "padawan". He spelled it "padawon" and I told him it was "padawan". He told me that spelling came around after The Empire Strikes Back. I'm not entirely sure about that, but regardless I think it is irrelevant as it has been spelled "padawan" for as long as I can remember and that spelling is widely accepted as the true one. So, which one is it?
