imbecility
Extreme mental deficiency
Imbecility is profound stupidity or foolishness—the quality of being an imbecile.
The word carries more bite than simple foolishness, suggesting mental deficiency: The sheer imbecility of the plan astonished everyone.
Once a clinical term for moderate intellectual disability, it now functions purely as an insult describing idiotic behavior or thinking.
