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: 
English like many languages allows substantive adjectives, i.e. adjectives that are used in place of nouns. Using the definite article (*the*) is usually helpful to indicate that you are using such an adjective:

> 
> Out with the old, in with the new.
> 
> 
> What becomes of the broken-hearted?
> 
> 
> Soak the rich.
> 
> 
> Fortune favors the bold.
> 
> 
> 

As "A new is being created" uses the indefinite article (*a* / *an*), I think it would confuse most English-speakers, who would ask "a new what?" If you want a generic message indicating that something new is being created, you could try to find a generic term for whatever it could be:

> 
> A new item is being created.
> 
> 
> 

Since the act of creation implies newness in itself (one does not by definition create old or existing things), perhaps you can reword to replace one or the other. A software status message could be as simple as

> 
> Creating …
> 
> 
>
From Merriam-Webster:

> 
> **new**, *noun*
> 
> 
> **1** : a new thing : something new {the *new* ever supplants the old}; especially : the first phase {in the *new* of the moon}
> 
> 
> **2** : FRESHNESS, NEWNESS {wear the *new* off these shoes}
> 
> 
> 

Note that Merriam-Webster lists adjective, noun, and adverb forms of *new*. (The adverb is usually used in combination, as in "*new*-mown grass.")

For your sentence, you could say something like, "This is the creation of *the new*."
