How to Write 弪 (jìng) — Meaning “Radian.”

Imagine a bow (弓) bending into a perfect curve, and think of the right part 巠 as looking like a small "road" or "path" that follows that curve. This helps you recall that 弪 means radian, a unit for measuring curved angles.

Write the left radical 弓 first with three strokes: horizontal, horizontal, then a vertical hook. Then write the right part 巠 with five strokes: a short top horizontal, a left-slanting stroke, a middle horizontal, a vertical line, and a final bottom horizontal. A common mistake is making the right part too wide, so keep it narrow and balanced with the 弓.

弪 (jìng) uses 巠 on the right, while 弛 (chí) uses 也 (yě) and means "to relax" or "loosen". 弟 (dì) is completely different, meaning "younger brother", and its shape has no 弓 radical. Focus on the right side: 巠 is unique to 弪.

弪 is a specialized mathematical term used mainly in textbooks and academic discussions about angles and trigonometry. It appears in words like 弪度 (radian measure) and 弧弪 (radian), but is rarely seen in everyday conversation because it is a technical character.

Common words containing 弪 include: 弪度 (jìng dù) — Radian measure.; 弧弪 (hú jìng) — Radian (mathematical term).; 一弪 (yī jìng) — a radian.
