Is it derived from Latin?
I'm assuming as a large part of the English language is I'm just thinking maybe it could be a bastardization of a phrase that makes more sense

Only ~35% is latin, another very large chunk is greek, and then you have French and German influences. It's an awful language. Heh
Don't forget Norse 😁
