The etymology of this word comes from an invisible proto-language. If you're confident you know the etymology, feel free to add it, but reader beware should the etymology be added by someone other than the creator of the language!
I finally was able to find a language where I could coin a word in honor of my sweet boy Roman. His name is too Indo-European to use comfortably in most languages, but here it seemed all right (especially since the word for "cat" probably wasn't ever going to be used).
