依存
いぞん · izon · JLPT N1 · noun
dependence
依 — person radical 亻 + clothing 衣
A semantic-phonetic compound: 亻(person) gives the meaning of relying on someone, while 衣 (yī, clothing) supplies the sound. The original sense pictured a person leaning on or wrapped in clothing, extended to the modern meanings of 'rely on,' 'depend on,' and 'according to.'
存 — 才 (talent/sprout) + 子 (child)
Originally written with 才 (a sprout breaking ground) over 子 (child), suggesting a child being raised or kept alive. The character came to mean 'to exist, to remain, to preserve.' Modern uses like 存在 (exist) and 保存 (preserve) reflect this core sense of continued being.
