I'm not sure about this example - it may be the same as the standard ninaru.
Amatuka
Yeah, it looks ninaru and kotoninaru is the same.
Miki
OK that's all tidyied up - the remaing question is whether 'ninaru' and 'kotoninaru' actually deserve separate entries.

I don't understand example ex #3704 in the context of this grammar point...

I also don't see ex [#3704] as fitting this grammar structure. And, I don't know for sure about the JLPT level, but I learned this in an upper basic course which I would guess translates to JLPT 3.

I have found references to this grammar topic in JLPT3 texts.

I agree with Amataka and Miki. ことになる is just the になる grammar used with the verb nomilizer V-ruこと.

Same as [koto ni naru], we should merge both articles. Which syntax do we use: seperated by space or in one word?

Watashi wa nihon go no sensei ni yaru koto ni naru.
