There were many lingua francas of which French was supposedly the first global lingua franca. That changed and it became English (from what I understand). We will probably see another language become the lingua franca, so my question is: should it be English? Are there better candidates out there? Why / why not?
Furthermore it’s the only European language there is. Every other language spoken in Europe descends from the Eurasian steppe. Well, most likely with a pinch of Kaukasian. It’s several millennia overdue that we honour the Euskari!
Basque it is!
