移住
いじゅう · ijuu · JLPT N1 · noun
migration
移 — grain 禾 + many 多
Originally a semantic-phonetic compound: 禾 (grain) gives the meaning and 多 (duō) suggested the sound in Old Chinese. It first referred to transplanting rice seedlings, then broadened to mean 'to move, shift, or relocate' in general.
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'.
