The kanji 宿 is a phono-semantic compound (形声文字, keisei moji). It combines the phonetic element 𡨄 (pronounced shuku or shu, representing a sound) and the semantic element 宀 (an abbreviation of 宀 meaning roof/house). The phonetic element provides the sound, and the semantic element indicates the meaning associated with a place of dwelling or rest. The original form depicted a person 人 resting 止 under a roof, which evolved into the present character.
