Preface: to avoid the annoying repetition and likely erroneous omission of quotation marks, I’m taking the liberty of using bold italics instead. Please forgive me.
There are a couple of common words in our lexicon that we rely on a lot, and they describe the fundamental purpose of Roget’s Thesaurus: synonym and antonym. Interestingly, their derivation makes them misnomers.
Looking at their etymologies, both words are derived from Greek. Synonym came from syn- and onyma, meaning with or together, and name. Similarly, antonym came from anti- and onyma, meaning against, and name. The primary definitions of synonyms and antonyms are, respectively, similar and opposite words. Name is nowhere in sight, and it’s hardly synonymous with word.
So, now that I’ve gotten that out of my system, I’m risking my poetic license to create a few related terms of my own:
Anonynym – word that has no meaning (anonym is actually a word, meaning anonymous person or pseudonym, but this is different)
Decoranym – word that just looks good
Duonym – word that has a double meaning
Lacronym – word that leaves something to be desired
Macronym – word that means everything
Manynym – word that has multiple meanings
Maximym – word that has the most meanings
Mininym – word that has little meaning
Mononym – word that has one meaning
Nanonym – word that has very little meaning
Narcissanym – word that thinks it owns the rest
Pandemoninym – word that sows confusion
Warynym – word with questionable meaning
I’m sure there are others, but I think I’ll stop here. I’m starting to strain my craninym.


Since I was little, I've been intrigued by words. My favorite is is an oldie, antidisestablishmentarianism🙂.
Bob, your mind is quite "nymble" today. :)
