American English versus British English.
There are different dialects for most languages. Makes sense to me. Is there a native language still spoken in Scotland? I mean, I'm aware of Gaelic in Ireland, but I haven't heard of a native language for Scotland.
EDIT: Google, you make me feel dumb sometimes.

EDIT2: I knew this, too, but my bain's RAM was broken. I've been to Iona, Scotland, but it was years ago, and learned about Gaelic for the first time during my visit.
