The Elo rating system in chess is often written in capital letters, but it is not an acronym. It is named after its creator Arpad Elo.

A double twist is that in the original Hungarian his name is Élő that means "Live". For the first few decades of hearing "Élő"-score, I just assumed it meant your "live" score, as in your score at the current time. I wonder if others had that confusion too.

In chess there's even a difference between the "live elo rating" which is calculated every match, and the official FIDE rating updated every month.
