Bathsheba
^it's buses and butter not bases and batter^
I have never heard anyone pronounce bus and butter as bas and batter
. I have only ever heard bus pronounced with a short 'u' (in the south) or with a long 'u', to rhyme with could (in the north).
But bas? Batter? How odd. Where have you heard this trisher? Genuine question, I am interested.
I've heard these pronunciations too, from my SiL.
She is northern, but had a very middle-class upbringing (boarding school), and is actually quite snobbish, unlike many other people I know who had a similar education
Although I am pretty sure that she would have originally used the typically-northern pronunciations, like her brother - my OH - I think she changed how she spoke so as not to appear 'common'.
The trouble is, she has overdone it, and it is the use of 'a' in place of 'u' where it is very noticable. It always makes common old me laugh inwardly when, for instance, she talks about ordering a 'carry' instead of a curry. ?
