How to Write 癖 (pǐ) — Meaning “habit; addiction; hobby”

Imagine a person (辟) lying in a hospital bed (疒) because they cannot stop a bad habit, like washing their hands 100 times a day. The radical 疒 reminds you it is an unhealthy obsession, while the right side 辟 can be thought of as "bi" for "be obsessed." This visual helps connect the illness radical to the idea of an addiction.

Start with the radical 疒: write the dot, then the left stroke, then the horizontal and left-falling stroke. The right part 辟 is written with 尸 on top and 辛 below; be careful to make the 尸 small and the 辛 balanced. A common mistake is to make the left radical too wide or to forget the dot inside 疒, so keep the overall shape narrow and even.

癖 (pǐ) means a habit or addiction, especially an unhealthy one, while 瘭 (biāo) refers to a type of sore or blister, and 瘰 (luǒ) means scrofula or swollen lymph nodes. Visually, 癖 uses 辟 on the right, 瘭 uses 票, and 瘰 uses 累, so the radical 疒 is the same but the right parts differ completely. In usage, 癖 is common in everyday words like 洁癖, while the others are rare medical terms.

癖 is used in words like 洁癖 (obsessive cleanliness) and 癖好 (a particular hobby or interest). Culturally, 癖 often implies an excessive or compulsive tendency that is seen as a minor flaw, like being a "bookworm" (书癖). It is not a neutral word for "hobby"—it always carries a sense of intensity or oddness.

Common words containing 癖 include: 洁癖 (jié pǐ) — Obsessive-compulsive desire for cleanliness; germaphobia.; 癖好 (pǐ hào) — hobby; particular interest; 书癖 (shū pǐ) — Bibliomania.
