My wife is looking for w word she vaguely recalls, a term for someone of rigid, fixed beliefs who has little tolerance for the worldviews of others. She thinks it might have “idio” in it somewhere or a short “i” sound.
Naturally, possibly due to the power of suggestion, I can’t think of such a word once she’s told me she’s mentally blocked on it.
I’m guessing she’s looking for a noun, not an adjective like “inflexible.”
Any guesses?
