When "such a" and when just "such"

Hello everyone,
I am interested in knowing when one can use the words “such a” and when just “such”. I have read sometimes sentences like this one:
[I had never seen such a beautiful woman]
Also I have seen the following:
[I would never enter such a house]
And also
[This town is full of such houses]
What is the difference in these examples.
Thank you

singular and plural

Hi Miguel

The word such can be used to refer to the extreme degree or nature of something:
I had never seen such a beautiful woman. = She was the most beautiful woman I had ever seen.
I had never seen such beautiful women. = They were the most beautiful women I had ever seen.

[color=white].
The word such can also be used to refer to a particular type of thing (the type would be specified elsewhere in the context):
I would never enter such a house. = I would never enter that type of house.
This town is full of such houses. = The town has many houses of that type.
.

That use would be equivalent with “so beautiful a woman”, etc., wouldn’t it?

Thank you so much, Amy for the reply.
Still one more. Can one use “such” without “a” with singular words, like “I have not seen such woman”?
Regards

Hi Miguel

I definitely would not use that wording. What was the meaning you intended with “such woman”?

That would depend on the noun. It’s no problem if the noun is uncountable:

  • I can hardly imagine what it would be like to have such wealth.
  • We had such fun at the party!
  • I had never seen such chaos.
    .

Thanks a lot Yankee!
I think I got it right
