Question: In some languages "new" could be used both as a noun or as an adjective. I read that in English, "new" is only an adjective. Is it true? When I say: "a new", is it wrong? How else can I properly say something along the lines "a new"?

In other words, is it ok to say: "a new is being created"? If not, how to say it properly?

Edit:

Example - hmm, I cannot really think of one. Maybe: "a miracle is when a new comes to life out of nothing". I try to *name* the result of a creation.

The problem is, in my native language there is no distinction between "new" as a noun and "new" as an adjective. "Newness" is, if I understand correctly, the general quality of "a new" or of "something new", hence it is a bit different from what I'm looking for.

"The new" is almost perfect - but I'm not sure if I can use "the" as this is the first time I talk about that "new".

Answer: 
A bit more context would help. It sounds like you want to say:

> 
> Something new is being created.
> 
> 
> 

I cannot think of a way to use "a new" where "new" is a noun, but "the new", as in "Out with the old and in with the new." is correct. In that case, it is called, I believe, an [ellipsis](http://en.wikipedia.org/wiki/Ellipsis_%28linguistics%29).
The most common use of "new" as a noun is "out with the old, in with the new."
