From Middle English dumb (“silent, speechless, mute, ineffectual”), from Old English dumb (“silent, speechless, mute, unable to speak”), from Proto-Germanic *dumbaz (“dull, dumb”), from Proto-Indo-European *dʰewbʰ- (“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”). See also deaf.

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.
