> Japanese is a language isolate, a language that is not related to any other known language. Someone will reply that it's distantly related to Korean, but this is a fringe theory in linguistics that is not widely accepted When using some strict definition of "related" (e.g. "neither language is a strict descendent of the other"), that may be true, but anybody that's studied both languages has probably noticed that there's an eery similarity between the two, even if it's merely the result of many centuries of cross-pollenization.... My own experience is not so great, I've only studied Korean a bit, but I did study it in Japanese (which I know fairly well), and the similarity made it a lot easier, because so many things corresponded 1-to-1... However Korean friends that are fluent in Japanese constantly rave about how easy it was for them to learn, not just because of the huge amount of shared Chinese-derivative vocabulary (many words are completely identical, with formulaic changes in pronunciation), but because the whole structure of grammar, sentence/conversation-planning, idioms, etc, is so similar that a huge proportion of their Korean instincts pretty much just work as-is in Japanese.
