  • Usage


    In standard use, nonplussed means ‘surprised and confused’: the hostility of the new neighbor's refusal left Mrs. Walker nonplussed. In North American English, a new use has developed in recent years, meaning ‘unperturbed’—more or less the opposite of its traditional meaning: hoping to disguise his confusion, he tried to appear nonplussed. This new use probably arose on the assumption that non- is the normal negative prefix and must therefore have a negative meaning. Although commonly encountered, this modern use of nonplussed is not considered part of standard English, and is better replaced by unperturbed, unruffled, unfazed, or composed
