dumb
Not at all bright
Dumb originally meant unable to speak—a meaning that persists in deaf and dumb and struck dumb with amazement.
The sense shift to stupid now dominates casual usage: That was a dumb idea, Don't be dumb.
This evolution has made the original meaning problematic, as calling a mute person dumb now risks implying stupidity.
To dumb down is to simplify for a less sophisticated audience.
