noun + の + verb + こと VS noun + を + verb + こと


I was just wondering if the following sentence was correct:

> 日本語の話すこと

It doesn't sound wrong to me, as the whole「話すこと」part becomes a noun, but I'm
not quite sure.

I think the more standard way to say it would be:

> 日本語を話すこと

Then the verb 「話す」is not a part of the noun「こと」

What do you think?




日本語を話すこと is "the act of speaking Japanese". This is a well formed, perfectly
normal phrase (not sentence).

日本語の話すこと is grammatical but weird. If we treat の as the possessive particle
then we have "the act of speaking which is the Japanese language". This makes
no sense to me. I cannot think of a way to parse it that does make sense.

If we treat の as the subject particle ([see
this](https://japanese.stackexchange.com/questions/12825/how-does-

then we have "the act of the Japanese language speaking". I could possibly
imagine this in some poetic context but I don't think you would find it in
everyday life.
