I have recently encountered a peculiar thing. While I was watching a Youtuber from England I heard him pronounce words like "everybody", "God" etc the American way with an /ɑ/ instead of an /ɒ/. This seems strange to me because in any other words which had the same sound he pronounced it the English way with an /ɒ/. I did some research about it and I found that there are other people who use the American phoneme only in certain words like those above and stick to /ɒ/ for the others. Is this a feature of modern speech in England? Is it considered odd to do this? Thank you in advance!
