comeuppance

Bouyed by Tejano Insider I went ahead and read this story were as I read I stumbled upon this word: comeuppance. Always being upanted by my curiosity I headed deep into the entrañas of the internet and quickly asked Merriem Webster what’s up with that word. They had this to say, yet it seems the meaning differs widely across the lexicographers web because word reference has this to say. One would think its use somewhat obscure yet the opposite is quite the contrary. Google gave less than a thousand hits shy og 600 thousand ones. So, where does this word come from? Etymology is sketchy with Merriem-Webster offering little clues.
