Listening to Karen Armstrong read, her cultivated Oxbridge accent is soothing. She uses ‘et’ for the past tense of ‘eat’ and pronounces ‘prance’ and ‘trance’ with the same a as ‘dance’ and ‘glass’ in the British Received Pronunciation. What I wonder is why that a occurs also in New England, even though its development occurred in England after the colonies were founded and so did not enter American English except in Rhode Island and other New England speech communities.
