I once went to Norway and it seemed to me like they were speaking German with a Geordie accent.
Of course I'm probably doing a terrible impression of each in my head.
I’m Scottish and pronounce the two words quite differently. “Bairn” sounds like “bear” with an “n” at the end and “barn” has a much harder “a” sound.
Interestingly, “burn” is a common word for a small stream in Scotland, but I digress.
