Scandinavia is Sweden, Denmark and Norway. A thousand years ago they used to speak the same languange. The languages are still simmilar enough for them to understand one another (most of the time). These languages are so-called germanic languages. They are related to German, Dutch and English, to name but three. Finnish is a so-called finno-urgic language. It is related to Hungarian and some of the Baltic languages. Scandinavia is thus defined by 1) geography; and 2) language. Iceland speaks a language very simmilar to what the Vikings spoke, but geography precludes them from being considered Scandinavian.
