I was just typing a work ticket into my system in faux Elizabethan English (because, you know, it's a slow day), and was thinking about the "Y" like character that used to be used to represent a "th" sound (the name of the character is escaping me at the moment, but you know what I'm talking about). Anyway, it dawned on me that since "Thule" was a word that meant...what, cold? winter? something like that, anyway, it was possible that the word "Yule" was actually "thule", and had just been taken into modern English with a "Y" sound by mistake.
So, am I on to something, or did I just make up my own folk etymology for the word "Yule"?
