According to my mother, her grandmother always said she liked her coffee "brindgin hot." (I have no idea how to spell the operative word, but I have tried to convey a sense of how she pronounced it with the spelling. That is, short "i" soft "g" and short "i"...) By this she meant that she liked her coffee so hot it would burn your mouth.

Now this may have been a made-up word or a family word with no real derivation, but I wonder if it might be a very old word or a distortion of a word. Ma was born in 1875 and raised in the rural South. The South preserved many old English words and pronounciations and some very odd sound-alikes for non-English words. She and her parents were literate, but I'm sure they were surrounded by and affected by those who were less so.

Any guesses as to where such an odd word could have come from?
