The kanji 宿宿 is a phono-semantic compound (形声文字; keisei moji). It combines the semantic component 宀 (うかんむり; ukanmuri), which signifies "roof" or "house," with the phonetic component 告 (koku), which provides the sound and contributes to the meaning of "to announce" or "to tell." The combination suggests a place where one announces their arrival or is sheltered under a roof, hence "lodging" or "inn." Over time, the character evolved to represent not just inns, but any place where one stays.
