Additional context:
Native speakers of my mother tongue do not all understand each other due to some pretty extreme dialects. Now that I’m in Europe, I’ve noticed multiple instances of people sometimes not understand the dialect of someone from a village 10-20 km away…
In contrast, for example most American, British, and Australian people can just… understand each other like that?? I never thought much about it before but it’s pretty incredible
I had a roommate from Manchester (UK) for a couple months back in college. I’m American (US). He seemed to have no trouble understanding me, but I usually couldn’t understand what he said without him repeating it multiple times.
Even Americans cant always understand Americans.
Perhaps that has something to do with American’s being all over social media/most influencers?
My guess was that it was probably due to Hollywood, but some form of mass communication, almost certainly.
