dumbとは

意味・読み方・使い方

語源 1

From Middle English dumb (“silent, speechless, mute, ineffectual”), from 古期英語 dumb (“silent, speechless, mute, unable to speak”), from Proto-West Germanic *dumb, from Proto-Germanic *dumbaz (“dull, dumb”), from Proto-Indo-European *dʰewbʰ- (“to whisk, smoke, darken, obscure”).

The senses of stupid, unintellectual, and pointless, which are found regularly since the 19th century only, probably developed under the influence of German dumm and Dutch dom. Just like the English word, these originally meant "lacking the power of speech", but they developed the mentioned senses early on.
