stupid
Lacking basic sense
Stupid describes a lack of intelligence or good judgment.
A stupid person doesn't think clearly; a stupid decision shows poor reasoning.
The word ranges from clinical assessment to casual insult: That was a stupid thing to say.
Stupid also means pointlessly annoying: This stupid printer won't work.
As a noun, stupid addresses someone directly: Hey, stupid.
