What does the last の in "おどるのはたのしいのです。" mean/do?


I'm having trouble understanding the grammar of this sentence:

> おどるのはたのしい **の** です。

I understand it means, "Its fun to dance," but I'm struggling to understand
why **の** is placed here: おどるのはたのしい **の** です。




It's something called an explanatory-の.

  * [What is the meaning of ～んです/～のだ/etc?](https://japanese.stackexchange.com/q/5398/5010)
  * [Wasabi: Explanatory のだ (んだ)](https://www.wasabi-jpn.com/japanese-grammar/explanatory-noda/)

So the last の turns "It's fun to dance" into "It's that it's fun to dance".
This の is a kind of a nominalizer that wraps everything before it and forms a
noun clause.

  * 楽しい。  
Fun.

  * 踊るのは楽しい。  
Dancing is fun.

  * [踊るのは楽しい **の** ]  
[ **that** dancing is fun]

  * [踊るのは楽しい **の** ]です。  
(It) is [ **that** dancing is fun].

Note that you need some context for this sentence to make sense. For example,
when the listener is wondering why you're dancing, you can say this to explain
the reason.
