稲光
いなびかり · inabikari · JLPT N1 · noun
lightning
🌾⚡ 稲 rice + 光 light = rice-light: old belief said lightning ripened the rice
Compare 稲妻 (inazuma), literally rice-wife, a poetic word from old lore that lightning fertilised the rice. 稲光 keeps the rice and adds the light: a flash over the paddies.
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).
