Grammar explanation 

We can use so and such to intensify adjectives, adverbs and nouns.

Adjectives and adverbs

We can use so with an adjective or adverb to make it stronger.

It's so hot today!
She looks so young in that photo.
He walks so slowly. It's so annoying!

If we are using the comparative form of the adjective or adverb, we use so much to make it stronger.

They were so much more innocent when they were younger.
I work so much more quickly when I can concentrate.


With a noun or adjective + noun, we use such to make it stronger. 

You're such an angel!
It's such a hot day today!
They're such lovely trousers. Where did you buy them?

However, when we use much, many, little and few with a noun, we use so to make it stronger.

There are so many people here!
I've had so little time to myself this week.

Saying the result

We often use these so and such structures with that and a clause to say what the result is.

It was so cold that the water in the lake froze.
He was such a good teacher that we all passed the exam.
There's so much noise that I can't think!

why is My cats have got so gorgeous eyes wrong? Can't we say very/so gorgeous?

Hi bahar-1,

It's because "gorgeous" is part of a noun phrase: "gorgeous eyes". We need "such" because of the noun "eyes". 

But "so" can be correct if we rewrite the sentence --> "My cats' eyes are so gorgeous". Here, "gorgeous" is by itself, not part of a noun phrase, so "so" is the right word to use.

I assume 'gorgeous' is an adjective, logically, we shall used 'so' to emphasis the meaning.
However, 'gorgeous' come after 'eyes'.
'gorgeous' is an adjective to describe the 'eyes', so we should treated 'gorgeous eye' as a noun.
So, 'such' is the correct answer is this case.

I'm doing some exercises about key word transformation and I got one aswer correct and one incorrect on the same matter. Could you please explain why?

He was the kindest person I had ever seen. (SUCH)
I had never seen such a kind person before. (Got it correct)

This is the strangest music I have ever heard. (STRANGE)
I have never heard such strange music before. (Got it wrong because I answered "...such a strange...")

Hi  jacksondjackson,

The reason one is correct and the other not is related to the nouns in the sentences: person and music.

Person is a countable noun, so 'a' is needed. Music is uncountable so no 'a' is used. You would need to say 'such a strange piece of music'.

i got wrong in number 7.I thought so but the answer is such.Can anyone explain me please?

Hi Khine Zin Nyein,

It's because there is the noun 'students' in the phrase: "such hard-working students".

Use 'so' if there is just an adjective in the phrase, e.g. "I've never had students who are so hard-working".

Does that make sense?
