But, um, what do the people in Spain speak if not Spanish?
In addition, there are several localized languages, that are not "official" but "recognized": Aragonese (Aragon), Asturian (Asturias), and Leonese (Castile and León).
And there are countless dialects of each.
IE is IrEland because IR is IRan, and Iran comes before Ireland alphabetically.
