In a prior post, I mentioned the scene from Casino Royale where Vesper Lynd says, “I’m the money” and Bond responds, “…every penny of it.”
I suddenly started wondering why Bond would say the word “penny,” given that it’s a name for a unit of American currency. Shouldn’t he of said… “pence” or “quid” or something?
Well, it turns out I’m pathetically uncultured and American-centric. AI set me straight:
>Your instinct has it backwards — "penny" is about as British as currency words get. It's Old English (penig), it's the name of an actual British coin (pre-decimal pence, and the 1p piece since 1971), and it's woven through the idiom: in for a penny, in for a pound; a penny for your thoughts; the penny dropped; penny-pinching; spend a penny. Americans use "penny" too, but only colloquially — the US coin is officially a cent. So if anything, "penny" reads as the Anglophone-original and the American usage as the borrowing.
I’ve embarrassed myself.
