non-plussed (comparative more non-plussed, superlative most non-plussed)

From nonplus (“state of bewilderment or perplexity”, noun) or nonplus (“to bewilder or perplex (someone)”, verb) + -ed (suffix forming adjectives, and the past tense and past participle forms of verbs). Nonplus (noun) is derived from Latin nōn plūs (“no further, no more”), from nōn (“not”) + plūs (“additionally, more; further”) (ultimately from Proto-Indo-European *pleh₁- (“to fill”)). The etymological sense is similar to being left speechless as a result of confusion: the nonplussed person can say or do “no more”.
Sense 2 (“unaffected”) is probably from a misinterpretation of the first element of the word as the prefix non- meaning “not”.
nonplussed (comparative more nonplussed, superlative most nonplussed)
Since the mid 20th century, originally in the United States, nonplussed has acquired the alternative sense of “unaffected, unfazed”. In 1999 this sense was considered a neologism, and in 2005 it was still described as “not yet accepted as standard usage” by the Compact Oxford English Dictionary.
