Will English language lose weight in Europe after Brexit?

Yes, because the UK was the only member state to have chosen English as its official EU language.

No, because it is still official in Ireland and Malta, and they will veto any attempt to withdraw its official status in the EU.

Yes, because the number of native English speakers in the EU will be drastically reduced.

No, because the US is still the cultural hegemon and English an international language, especially among youngsters.
