Synonym translates one word to one other word, so it won't help you
here. You could use the contrib/dict_xsyn module, which does exactly
what you suggest. Or if you want to stick to features that are in core,
the thesaurus dictionary would do, though it seems to be a bit more
complicated to set up.
