神聖
しんせい · shinsei · JLPT N1 · noun
holiness
⛩️ 神 (god) + 聖 (holy) = holiness that belongs to a god
聖 alone means holy or saint. Adding 神 (god) makes it the sacredness of the divine, and it also covers the dignity of sacred places and things.
神 — 示 (altar/spirit) + 申 (lightning, phonetic)
神 combines 示, depicting an altar associated with rituals and spirits, with 申, originally a pictograph of lightning streaking across the sky. Ancient people saw lightning as a manifestation of divine power, so 申 contributes both sound and the idea of awe-inspiring force. Together they mean 'spirit' or 'god'.
