to glow
✨ 焕 (radiant, has the 火 fire radical) + 发 (emit) = to emit radiance, to glow
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.'
