小知识
Today, most of the time someone or something is described as dumb when it shows a lack of thought, like your dumb idea of wearing flip-flops in a snowstorm.
Dumb is the Old English word that means “mute, speechless,” and itself came from an even older word dheubh meaning “confusion, stupefaction, dizziness.” Today, dumb still means “unable to speak,” but it doesn't have anything to do with intelligence. Its other meaning, however, does. If you make a dumb mistake, it's something you could have avoided if you thought it through first.

dumb，mute，speechless
dumb一般指根本没有说话能力，常指动物；mute强调为某种原因而沉默；speechless指哑口无言的。dumb，mute这两个形容词均有“哑的，不能说话的”之意。dumb可与mute换用，但dumb指原本没有说话能力或失去了说话能力。mute多指因后天疾病而引起的聋哑，有时也指因故不说话。
