- More recently, nonplussed has been used to mean “indifferent or unexcited,” a contradictory second meaning.
- One explanation for this is the analysis of nonplussed as non– “not” + plussed, interpreted as “not puzzled, perplexed, bothered, or impressed,” when in fact plussed has no meaning in English.
