Is Slavic the most common language spoken in northern Europe?

No, Slavic languages are not the most common in Northern Europe.

Here's why:

* Northern Europe is dominated by Germanic languages: The most spoken languages in Northern Europe are Scandinavian languages (Swedish, Norwegian, Danish, Icelandic, Faroese) and English, which are all Germanic languages.

* Slavic languages are primarily spoken in Eastern and Central Europe: While some Slavic languages like Polish and Czech are spoken in the south of Northern Europe, their presence is not as dominant as Germanic languages.

Therefore, Slavic languages are not the most common languages in Northern Europe.
