住宿

stay
🛏️🏨 住 (reside) + 宿 (lodge overnight) = stay the night, get accommodations
Both characters mean to dwell or lodge: 住 is the verb to live or reside, and 宿 means to stay overnight. Stacked together they name the act of putting up somewhere — booking a room, getting a bed for the night.
住 — person radical 亻 + 主 (master/zhǔ, phonetic)
住 is a semantic-phonetic compound. The left side 亻 (person) gives the meaning—something a person does—while 主 supplies the sound, originally 'zhǔ' (master, a lamp standing in place). Together they suggest a person staying put, yielding the senses 'to live, dwell, reside, stop'.
