In reading the Associated Press Stylebook 2008 again, I see that North America includes Canada, Mexico, the United States and the Danish territory of Greenland.
Greenland? In North America? I guess I just thought it was . . . somewhere else.
And, the stylebook explains, “when the term is used in more than its continental sense, it also may include the islands of the Carribean.”
Greenland and — sometimes — the Carribean islands? North America a lot bigger than I thought!
