存続
そんぞく · sonzoku · JLPT N1 · noun
continuance
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.
