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
Edit: thanks everyone, and clearly I didn’t think of certain parts of the UK when I was in the shower and thought of this…
As an Australian, it’s Irish accents that I struggle with the most.
Scottish I can deal with, probably from watching shows like Still Game and Burnistoun.
Most other UK accents are not to difficult to understand.
One odd thing, I was watching an USA wildlife documentary that was set in South Africa. I noticed they put forced subtitles on when ever the South African’s spoke in English. I found that bizarre as I’ve never had any trouble understanding when South Africans speak English.
I’ve seen subtitles on both Aussie and nz English in US shows
