No, Europe has more native German speakers. It is not "the most used language in Europe."
Yes, it is. We don´t use English in the everyday life, most of us don´t speak English anyway (40% in France and Germany do). Foreign movies and series are translated in sync and software is localized. So German is the most used language in Europe.
No, it is not. Try reading this carefully: German is the most common native language in Europe, but not the most commonly used. English is the most commonly
used language in the EU, followed by French and
then German, whether you like it or not. More people in all EU countries are likely to have learned English as a second language than any other and to use it in international commerce, diplomacy, cultural exchange, etc. Germans study English as a second language first and more commonly than any other as well.
That's just how it is, regardless of how you feel about it.
