黑夜
hēi yè · HSK 6
night
🌑 hēi = black, yè = night — black night, total darkness
The two characters literally stack: 黑 (black) + 夜 (night). Say 'hey, yeah' — hey, yeah, it got dark out. A redundant-sounding pair that emphasizes deep, pitch-black nighttime.
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.
夜 — 亠 lid + 亻 person + 夕 evening moon
夜 originally depicted a person (亻) under a roof (亠) with the moon (夕) beside them, evoking nighttime rest. The moon component 夕 carries the meaning of evening, while the surrounding elements set the scene of a person at night. Over time it came to mean 'night' in general.
