alt Hacker NewsBritannica lays it out for you, and yet you tilt at someone that lives there (vidarh) telling you the same?
> Scandinavia, part of northern Europe, generally held to consist of the two countries of the Scandinavian Peninsula, Norway and Sweden, with the addition of Denmark.
You've been found wanting in your claims.
> Some authorities argue for the inclusion of Finland on geologic and economic grounds and of Iceland and the Faroe Islands on the grounds that their inhabitants speak North Germanic (or Scandinavian) languages related to those of Norway and Sweden. Typically, when these other areas are added to Norway, Sweden, and Denmark, the group is called the "Nordic countries.”
The second quote you posted appears to directly support my stance, and that you think it shows my claim wanting throws your comprehension of the discussion into question.
Britannica is not authoritative, it is one view. It attempts to promulgate One Answer, not to capture the breadth of all English usage in all countries. It hedges itself with words like "generally".
I've never argued that the Britannica interpretation is invalid, just that mine is also valid. Nothing you posted contradicts that.
This all is like a French person getting annoyed at a Quebecois because they're using a different word. Or a Spaniard getting annoyed at an Argentinian. Different places use different words differently, and thinking it isn't so is simultaneously arrogant and ignorant.
