阴暗
yīn àn · HSK 7
dark
🌥️🌑 阴 (shade, overcast) + 暗 (dark) = dim and dark, like an overcast sky
阴 is the yin/shade side, the overcast gloom; 暗 means dark or unlit. Stacked together they describe low, murky light — a dim, dark, sunless dullness.
阴 — left 阝(mound) + 月 (moon)
Originally written 陰, combining the 'mound/hill' radical 阝 with 侌 (clouds covering the sun), suggesting the shaded north side of a hill. The simplified form 阴 replaces the phonetic with 月 (moon), reinforcing the idea of darkness, shadow, and the feminine yin principle opposed to 阳 (yang).
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.'
