Quite, rather and so with nouns
Quite can be used with a/an + noun. Before a noun with a gradable adjective, we use quite a/an.
It was quite a pleasant experience. (NOT It was a quite pleasant experience.)
Quite a/an is also used before a noun with no adjective.
The party was quite a success.
She is quite a woman!
Before a noun with a non-gradable adjective, we use a quite.
It was a quite perfect evening. (NOT It was quite a perfect evening.) (Perfect is a non-gradable adjective.)
Rather can be followed by an article + noun.
He is rather a fool.
That’s rather the impression I had.
Before a noun with an adjective, we can use a rather or rather a.
She had rather a good idea. OR She had a rather good idea.
So can be followed by an adjective + a/an + singular countable noun. Note that this is a rather formal structure.

Note that this structure is not possible without an article. If there is no article, we use such, not so.
