Countable in singular used without articles. Apple pie, red car, picked fence.

Something similar to " Noble, peasant, warrior, priest, all hated the new law"

What is the justification for using these nonuns without articles?

That example is treating those nouns like some kind of collective noun (although we wouldn't normally consider them collective nouns). We can use the zero article with collective nouns when making general statements about the group as a whole.

However we could also just as easily pluralize those same nouns. As plurals, the zero article would still apply when making broadly-applied generalizations about the group as a whole.

I think you would benefit from some self-guided research into the so-called "zero article". Try looking through some of the resources on this site first.

Since this thread seems to be going nowhere, as well as the OP failing to heed repeated feedback about making the same basic errors, I'm going to close this thread. Anyone who feels they have a valid reason can petition a mod via PM to reopen the thread.

@Vladv1, research the zero article, and if you still have questions, you may start a new thread about specific uses of it, not broad cases of "give me all examples" that you frequently ask for.

If you don't want those new threads summarily deleted or locked, be sure to carefully proofread and apply the extensive feedback you've gotten on proofreading your own posts before submitting them. If you can't (or won't) demonstrate some uptake on our feedback (not just the topic you're fixated on), then why should volunteers bother additional time?
