Well, not “medior” at any rate. That’s a fabrication, an anglicization.
Dutch typography regularly seems to use a superfluous colon to introduce a list of items – sometimes even a ‘list’ of one!
Eurocrat, Eurotrash, Eurospeak… prefixing something with “Euro” in English is often intended as a negative connotation. Unlike on the Continent.
