住居
じゅうきょ · juukyo · JLPT N2 · noun
house
🏠 住 (live) + 居 (dwell): two 'live' characters stacked, so juukyo is the place where you live
Both kanji mean to live or reside, so the compound doubles the idea and names the home itself. It is the formal word you will see on forms and documents for your address.
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'.
