I was having a debate earlier with a friend regarding the use of Americanisms in the UK and how certain words seem to have taken over or crept in. This is not the topic to debate here - but my general point was that lots of the words people complain are American are actually an Old English or similar word that were taken over by the settlers.
Anyway, I am sure that I have read on here ages ago that there are people who use the word 'Mom' in the UK. Possibly in the Midlands or the Black Country? I am not from anywhere near, or anywhere that does, but I thought I would post and ask to make sure I had not imagined it!
