English[edit]

Pronunciation[edit]

Etymology 1[edit]

From Middle English dumb, from Old English dumb (“silent, silent, speechless, mute, unable to speak”), from Proto-Germanic *dumbaz (“dull, dumb”), from Proto-Indo-European *dʰeubʰ- (“to whisk, smoke, darken, obscure”). Cognate with Scots dumb (“dumb, silent”), North Frisian dom, domme (“dumb, stupid”), West Frisian dom (“dumb, stupid”), Dutch dom (“dumb, stupid”), German dumm (“dumb, stupid”), Swedish dum (“stupid”), Icelandic dumbur (“dumb, mute”).

In ordinary spoken English, a phrase like "He is dumb" is interpreted as "He is stupid" rather than "He lacks the power of speech". The latter example, however, is the original sense of the word. The senses of stupid, unintellectual, and pointless developed under the influence of the German word dumm (which itself derives from Old High German tumb).
