Today's weird word is aristology. When I saw this one, I figured it had to be the study of something, especially with the "ology" hanging on the end.
I had no idea what the root word "arist" was though. Turns out, Ariston is Greek for dinner. Therefore, those who study dining are Aristologists and the art of dining is aristology.
Hmmm... who do you think might be hiring for me to be an aristologist?
Rare. the art or science of dining. — aristologist, n.
