"What a beautiful scenery!" - Don't say that!

"What a beautiful scenery!" - may sound correct to most of us but it's grammatically wrong.

"What beautiful scenery!" - may sound awkward but it's actually correct.

 

Do you know why?

So, we cannot say '...a scenery' or 'sceneries'. ;)

*It's simply because 'scenery' is an uncountable noun, just like 'furniture', 'information' and 'bread'.
