How to Write 痴 (chī) — Meaning “dementia; infatuated; silly”

Imagine a person who is so "sick with knowledge" that they become obsessed or foolish — picture a scholar with a fever reading books obsessively. The left side 疒 looks like a hospital bed, and 知 on the right reminds you of knowing too much to the point of madness.

Write the left radical 疒 first: dot, horizontal stroke, left-falling, then dot and lift (five strokes total). Then write the right side 知: first 矢 (left-falling, horizontal, horizontal, right-falling, dot; 5 strokes) then 口 (vertical, horizontal fold, horizontal; 3 strokes). A common mistake is making the 知 component too wide or misplacing the dots in 疒.

All three share the 疒 radical, but their right parts differ. 痴 has 知 (knowledge), meaning mental confusion or obsession. 疵 has 此 (this), meaning a flaw or blemish, as in a minor defect on skin. 痊 has 全 (complete), meaning full recovery from illness. Visually, 痴 is about the mind, 疵 about imperfections, and 痊 about healing.

痴 appears in words like 痴迷 (obsessed with a hobby or person), 痴心 (blind devotion, often in romance), and 痴呆 (dementia or mentally slow). In Chinese culture, 痴 is often used poetically for intense, irrational love — for example, 痴情 describes a person who loves without reason, a common theme in literature and films.

Common words containing 痴 include: 痴迷 (chī mí) — obsessed; infatuated; 痴心 (chī xīn) — infatuation; blind devotion; 痴呆 (chī dāi) — dementia; dull-witted.
