Right, just thought I would drop a note that the link in the sidebar to The Foreigner is fixed. Though the original site died, The Wayback Machine has come to the rescue. The Foreigner is a great Japanese guide in that it teaches you all the technical terms for conjugations, among other things.
Hopefully next time I make a book review I will remember that the masu form is ren'youkei, not rentaikei*. Ha ha. You know how that goes.
*Disclaimer: Just because you know the Japanese word for a conjugation doesn't mean you can have a linguistic discussion with a native. It's like talking about a dangling participle with an English speaker. Still, it's good to know your stuff.
