“Greenlandic”?
That is a lame name for a language. I think that disqualifies them for nation status.
I think Greenlandic has 437 different ways to describe cold... really cold... colder... *really really* cold... coldest... amazingly cold... cold-but-not-amazingly cold... etc
How about “Greenish”? We could also start referring to those who move from Greenland to the United States as “Greenish-Americans” (at least, we could if we were the hyphenating sort, which we are not).
