Also, although it's technically right, 'senpai' is the wrong romaji...
The 'n' turns into an 'm' when it's next to a 'p' or a 'b' ...

Although I realize many people romanize it that way, it really confused
me when I was first learning the kana. I therefore adopted the method
used in my first Japanese/English dictonary which was to always use 'n'
even before 'm', 'b', or 'p'. It makes sense to me, and makes it easier
to find things in unromanized Japanese/English dictionaries.

But no-one says 'senpai' ... that's wrong... it's said with an 'm'...
