Two words A and B are synonyms if they mean the same thing, and antonyms if they mean opposite things. But is there a word to describe the relationship where A means "neither B nor its opposite"?
For example: "Indifference" means "neither love nor hate".
I would like to be able to use it in sentences of the form: "What is a `neutralnym' for love?"
(The wikipedia page for the -onym suffix says that "anonym" is already taken, sadly, as this would have been a good neologism. That's why I used "neutralnyms" even though it mixes Latin and Greek roots.)
Edit: A further more example to illustrate what I am asking.
right and wrong are antonyms, and ambiguous is a neutralnym of both.
