nonplussed
C2Formal, Literary
Definition
Meaning
So surprised and confused that one is unsure how to react.
Less commonly (especially in North American usage), it can be used to mean 'unperturbed' or 'not disconcerted', a reversal of its traditional meaning. However, this usage is still widely regarded as an error.
Linguistics
Semantic Notes
Traditionally describes a state of mental paralysis brought on by shock, bewilderment, or perplexity. The contradictory meaning ('unfazed') is a language change in progress, primarily in North America, leading to potential confusion.

Frequency
The traditional meaning is predominant in published writing globally. The reversed meaning appears more in spoken and informal written American English.

FAQ
Frequently Asked Questions
In some informal North American usage, it is used this way, but it contradicts the word's historical and primary meaning. In formal writing and outside North America, this usage is considered incorrect.
It comes from the Latin 'non plus' meaning 'no more'. It originally referred to a state where one could do or say 'no more' due to perplexity.
No, it is a mid-to-low frequency word more common in formal and literary contexts than in everyday conversation.
Use it in its traditional sense ('bewildered') and provide clear context. Be aware that some readers, especially Americans, might misinterpret it, so consider if a simpler synonym like 'baffled' is more appropriate.
