What's Another Word for Synonym?

Well as most people know, this question doesn't have a real answer. Truth is, if you look up “synonym” in a dictionary, it will say something along the lines of “A word having the same meaning as another word in the language”. However, if you look up synonym in a thesaurus, you will find that the actual word synonym has no synonyms for it. It’s a little ironic I know, but I’m just answering a question, not defending the legitimacy of the entire English language... If you do want to debate the legitimacy of our language, try Webster, I hear he knows a lot about words.
