dim-witted
Lacking mental sharpness
Dim-witted means slow to understand, not very intelligent.
The image is of a light that doesn't shine brightly—mental illumination that's weak or flickering: a dim-witted sidekick in a comedy, It was dim-witted of me to leave the door unlocked.
The word is insulting but milder than stupid or idiotic.
