How to Write 綮 (qǐ/qìng) — Meaning “vital point; joint where bones and muscles meet”

Imagine a silk thread (糸) tied tightly around a door (啟, which looks like a door opening); when you pull the thread at just the right spot, the door swings open. That spot is the vital point, the 綮 — the crux of the problem.

Write the top component 糸 from left to right: three small strokes (left, right, center) then two longer strokes; make it narrower than the bottom. The bottom part 啟 has a left side 戶 (door) with a vertical stroke that should be straight, then 攵 on the right; common mistakes include making the top too wide or misplacing the horizontal stroke in 戶.

綮 (qǐ) has the bottom component 啟, while 紫 (zǐ) has 此 below and means 'purple'; 絓 (guà) has 圭 below and means 'to hang' or 'to obstruct'. Visually, 綮's bottom part is more complex with a slanted stroke and a '攵' radical, unlike the simpler bottoms of 紫 and 絓.

綮 is rarely used alone; it appears in classical idioms like 肯綮 (kěn qìng), meaning the crux or essential point of an issue. It is a literary term found in ancient texts such as the Zhuangzi, and still used today in formal writing to refer to the most critical part of a problem or argument.

Common words containing 綮 include: 肯綮 (kěn qìng) — the crux; the essential point; 綮处 (qǐ chù) — crucial part; vital point; 綮肯 (qǐ kěn) — crux; the most important part.
