The dictionary contains many words which start with "non", e.g. non-acceptance or nonacceptance (with a hyphen and without it). I tried to find out if I can build a new word by using the word "non" and a project's name (we can also generalize the project to any organizational group, but I'll use the term 'project' here), but didn't find enough useful information, therefore I'd like to ask you.
If I want to say that something does not belong to a project and the project is called "ABC", then is it correct to say:
This is a non-ABC thing.
Or maybe you have some better proposals how such things can be described in a shorter way than
This is a thing which does not belong to ABC.
I mean in this situation something what is not a part of the project ABC, i.e. is not contained in the project ABC.
Please note that the name of the project ABC is a noun and not an adjective. My main concern is that maybe the nouns have to be treated differently in order to build a "non-..." word.
