Etymology

Depicts the mouth () being stuck and not moving, like wood (), representing someone stupid or expressionless.

About

The character "呆" structurally integrates the elements for mouth (口) and tree (木), creating an ideogram that conceptually depicts a person standing with mouth open, immobilized like wood, which originally conveyed a sense of physical inertness or simpleminded slowness. Over time, this tangible representation of inactivity was abstracted to describe mental dullness, solidifying its primary modern meaning of foolishness or stupidity. While the character's composition has stayed unchanged, its semantic focus shifted from denoting physical states to emphasizing cognitive deficiency, and it concurrently acquired a secondary verbal sense meaning to stay or remain, likely through phonetic adaptation, though this usage remains ancillary to its etymological core.
