黑暗

dark
🌑 黑暗 = 黑 (black) + 暗 (dim/dark) — two dark characters stacked
黑 means black; 暗 means dim or dark. Together they form an emphatic compound meaning darkness. 暗 itself splits into 日 (sun) + 音 (sound), hinting at sun hidden so only sound remains.
黑 — top 里 over 灬 (fire) — soot from flame
Originally a pictograph of a person whose face was blackened by smoke from a fire, with the lower 灬 representing flames and the upper part showing soot stains. Over time the form was regularized into the modern shape, and the meaning broadened from 'soot-blackened' to the general color black.
暗 — sun 日 + sound 音 (phonetic)
暗 is a semantic-phonetic compound. The 日 (sun) component carries the meaning, suggesting absence of sunlight, while 音 (yīn, sound) provides the phonetic clue for the reading àn. Originally meaning 'dark' or 'dim,' it later extended to figurative senses like 'hidden' or 'secret.'
