to shine
✨💡 发 (emit/send out) + 光 (light) = send out light, to shine
发 means to emit or release, and 光 means light or brightness. Together they literally describe the act of releasing light — glowing, shining, or luminous. Think of a lightbulb the moment it switches on: it sends out light.
发 — simplified form of 發; from 癶 (two feet) + 弓 (bow) + 殳 (weapon)
The traditional form 發 depicted shooting an arrow from a bow, with 癶 showing outstretched feet and 弓 the bow, giving the core sense of 'send out, discharge.' From this came extended meanings like 'issue, emit, develop.' The modern simplified 发 also absorbed 髮 (hair), so it now covers both 'to send out' and 'hair.'
光 — fire 火 (top) + person 儿 (bottom)
Originally a pictograph of a person with fire above their head, depicting a torchbearer or the radiance from a flame. The character evolved to mean 'light' or 'brightness' in general, and by extension 'glory' and 'to shine.' The modern top component is a stylized form of 火 (fire).
