I can recognize my bias, but I grew up in the UK and so to me English is British-English.

Words like "fall" are something I've only heard on TV until moving here. (Or when visiting America.)

I appreciate American media is global these days, so people will pick up on the dialect, but it's still a little alien to me. I could hear "fall" a hundred times in films, but if everybody I ever spoke to about autumn holidays said "autumn" that's the one that feels more natural to hear.
