I have a question concerning the Grinch. In the e-mail it says that it was just a word Dr. Seuss made up, and yet, according to my Larousse: grinche, adj (Helv) grumpy, grouchy. The "Helv" means it is Swiss French.

I find this to be quite a coincidence. Does anyone have more info on how he might have come up with his name?
