なん、なんで、なんとか..
 

皆さんこんにちは、ちょっと問題がありますね。助けて ください。

First of all, what's the difference between なん and なに? They both can be written in 何...

Sometime I see/hear people say XXX なんです。
For example りんごが好きなんです。

Also, there is なんとか、なんで (<- I heard it from a JPOP song 「愛なんで」)... etc etc.. I am getting confused because you can't look it up in a dictionary...

お願いしますね！

Oops one more thing, from a JPOP song I heard 「なんとかなるさ」what does that mean?

何 can be read なん or なに

りんごが好きなんです. This なん has nothing to do with 何.

This is the ~んです form used with nouns and な adjectives. so な＋んです.

いきたいんです。たべたいんです。好きなんです。

All the same forms...

なんで means "why"

なんとか is a filler word meaning "something" when, for example, you can't think of the right word or name.

"What was that robot movie called again? "なんとか・E"?

And all grammar goes out the window with music.

It means "Things will work out somehow."

So what's the ん means in here？And how about なんだか____？
