Differences between もの こと and の


What is the differecne between, lets say those sentences?

> 面白いものを教えてください

> 面白いことを教えてください

> 面白いのを教えてください




もの is used for tangible objects. 面白いもの could refer to some interesting object.

こと is used for intangible objects such as concepts. 面白いこと could refer to some
interesting concept.

の is used to say, for your example "interesting one." Sometimes, こと and の and
transposable.

Of course, there is more nuance to all three, but what I said should explain
your sentence:

> ”Please tell me the interesting one/‘part.’”
