How to Write 鞲 (gōu) — Meaning “leather armguard; piston”

Imagine a leather (革) armguard that you wear on your arm to protect it while holding a hawk. The right part 冓 looks like a cage or frame, and you can picture the armguard as a leather frame around your forearm. This helps connect the leather component and the protective, structural image.

Pay special attention to the right side 冓: it has two horizontal strokes inside a frame, and the bottom part is like a vertical stroke with a hook. The overall shape is balanced, with the left 革 being slightly narrower than the right 冓. A common mistake is making the right side too wide or forgetting the small horizontal strokes inside the enclosure.

鞲 (gōu) means leather armguard or piston, while 鞠 (jū) means to bow or to bring up, and is used in words like 鞠躬 (to bow). 鞣 (róu) means to tan leather or soften it. Visually, 鞲 has 冓 on the right, 鞠 has 匊 (bent rice container), and 鞣 has 柔 (soft). All share the leather radical but differ in the right side component and meaning.

鞲 is rarely used in daily conversation; it appears mostly in technical terms like 鞲鞴 (piston) in machinery, or in classical references to falconry where 鞲袖 describes a leather sleeve for holding a hawk. It also appears in the idiom 鞲鹰 (to hold a hawk on the arm), reflecting ancient Chinese hunting culture. Learners may not need to memorize it unless studying specialized vocabulary.

Common words containing 鞲 include: 鞲鞴 (gōu bèi) — piston; 鞲袖 (gōu xiù) — leather sleeve; armguard; 鞲鹰 (gōu yīng) — to hold a hawk on the arm (with a leather guard).
