I'm looking for words similar to female, that can act as nouns and adjectives, but a) can so so only without changing form, and b) are unable to act as other parts of speech.
Is there a class or category for this sort of words?
P.S. I've used the Moby Part-Of-Speech database to filter a corpus of total 233,357 words to a list of just 5,423 words that are both nouns and adjectives (presumably, in the same form)...so (@Ricky) it's not quite "a hell of a list," but still one to reckon with. ;) For future reference, here's my list: https://pastebin.com/fG5gUeHP
