How to Write 腚 (dìng) — Meaning “buttocks”

Imagine a person sitting on a fixed stool — the left part 月 (flesh) represents your bottom, and the right part 定 means "fixed". So your bottom is fixed to the stool, and the character 腚 (dìng) sounds like "ding" as in your behind hitting a hard seat. This visual of a fixed rear end helps link the meaning and pronunciation.

Be careful to write the left radical 月 as a narrow vertical shape with two horizontal strokes, not three like the character 目. On the right, 定 has a roof-like top (宀) followed by a horizontal stroke and 疋 (a variation of 足). A common mistake is making the right side too wide — keep the whole character balanced, with the left side slightly smaller than the right.

腚 (buttocks) uses the flesh radical 月 on the left with 定 on the right. 朔 (first day of the month) has 月 on the left and 屰 on the right, and is unrelated to body parts. 朕 (used by emperors to mean "I, we") has 月 on the left but a different right side (关/灷). Visually, 腚's right side is 定 (with a roof), while 朔's right side is 屰 (an upside-down person) and 朕's right side is a combination not used in other common characters.

腚 is a casual, dialectal word for "buttocks" common in northern Chinese regions. It appears in everyday expressions like 屁腚 (buttocks), 光腚 (bare-bottomed, often used for babies or naked people), and 腚眼 (anus). Unlike formal words for buttocks (e.g., 臀部 túnbù), 腚 is informal and may be considered crude in polite conversation.

Common words containing 腚 include: 屁腚 (pì dìng) — buttocks (dialect); 腚眼 (dìng yǎn) — anus; 光腚 (guāng dìng) — bare-bottomed, naked.
