Requirement of の in this sentence?


I have come across this sentence:

> 毎日同じ **物** を食べる **の** は、面白くない

And I'm unclear as to why the の particle is required here since the noun has
been established using 物; is it okay to omit the の in this case or would that
grammatically invalidate the sentence?




The thing is that in this sentence, what is uninteresting is not the `物` but
the fact that you eat the same thing everyday.

Thus, you can "nominalize" the verb into `食べるの`.

After that, it's simply a matter of 「は」indicating the subject. You can thus
parenthesize the phrase as :

`「毎日同じ物を食べるの」は面白くない `

Note that this is similar, albeit with a different nuance to `食べることは` where
`こと` has the same function as `の`.
