Grant goes through the mailbag, offering answers about the terms “nosy parker,” “out of pocket,” and about whether the word “falsehood” has its origins in medieval garb. He also throws a question out to listeners about what is supposedly a mild British oath, “butternut!”
Dilettante, we heard from a linguist who suggested something similar, so maybe you’re on to something. I guess it’d be along the lines of saying, “Oh, FUDGE!”
OTOH, I think “butternut” is just a funny word, period! Sort of reminds me of Spanish speakers saying, “Caracoles!” or “Snails!” instead of “drat.”
