dear teachers, here are my questions:


I can't agree with such/such an idea.


and why do we choose either of them? does it have anything to do with the noun being countable or non? what about the following sentence:

I never heard such/such a bad news.



thank you

I can`t agree with you on such ideas / such an idea / such an awful idea.
I never heard such bad news - no article when you have an uncountable noun or a noun in the plural.
I never heard such a bad piece of news / such bad pieces of news.

It was such bad weather.
It was such a bad day.
