nonplussedとは 意味・読み方・使い方

別の表記

• non-plussed

語源

From nonplus (“state of bewilderment または perplexity”, noun) or nonplus (“to bewilder or perplex (someone)”, verb) +‎ -ed (suffix forming adjectives, かつ the past tense かつ past participle forms of verbs).^[1] 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”)).^[2] 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”.^[1]

使用する際の注意点

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,^[3] and in 2005 it was still described as “not yet accepted as standard usage” by the Compact Oxford English Dictionary.^[4]
