    I'm surprised to see ぬ in the top 50. Where does it come from...

    This seems strange to me. It's like saying "... although if you count articles and prepositions, then the is probably the most common." for English. Particles, auxiliaries, prepositions, and articles are just kinds of words. Then again the OP didn't specify. Commented Mar 30, 2014 at 7:23

    @hippietrail It depends on your theory of grammar. Do you consider 及ばない one word or two? Is 私の one word or two? The truth is, "word" isn't well-defined.

  • @snailboat: That is certainly true, which is why an answer shouldn't be based on one arbitrarily chosen definition of "word". At least you hedged your bets and gave both answers though (-: Commented Mar 30, 2014 at 9:29
