The word “barbarian” comes from Romans making fun of Northern Europeans’ speech. The Romans thought they all sounded like they were just shouting “Bar! Bar! Bar! Baaaaarrrr!” at each other.
It’s like if that “removed Ling Long” YouTube monstrosity from a decade ago became the word we use for foreigners 2,000 years from now.
That’s not true, it comes from greek to mean anyone who is not greek (which in ancient Greeks times, would be an insult)
