Re: Grammar question: toru -> tori
Thanks Josh. I was actually aware of tori being the -masu stem of toru, but the books I checked did not mention that this stem could be used for nominalizing. (The primary reference I checked being Chino's “Japanese Verbs at a Glance.”)
I guess my confusion with the -te form comes from the numerous examples like -te kudasai, -te aru, -te mo ii, -te oku, etc., where it is used very much like a gerund.
