What does koto mean? Koto is used in so may phrases...does it just mean 'things'? If I could think of some good sentence examples I would, but I don't know exactly what it is, so I find it difficult to use it myself. I know it can nominalize a verb like 'no' can (食べること and 食べるの are the same, right?), but it's used in other situations too. ありがとう。 Alright, thanks for the answers. I knew about ~koto ga aru, but I didn't know about the related to construction. That must be what I've been hearing. I haven't used these forums before, so I don't know if you can ask another question in the same thing, but I was wondering when do you use no at the end of a question? What's the difference between no and ka? Formality? Can no only be used with dictionary forms and ka only with ~masu forms?
