The kanji 夜 is a pictophonetic compound (形声文字, けいせいもじ). It combines two components: ⚫︎ The radical 亠 (also known as 高 or たかい "high") at the top. ⚫︎ The phonetic component 夕 (ゆう, yu), which means "evening" or "sunset". The original meaning of 夕 is related to the setting sun. The radical 亠 adds the meaning of "high," giving the combined meaning of "the sky is getting dark" or "the time after sunset." Over time, the character evolved to represent the entire period of night.
