養分
ようぶん · youbun · JLPT N2 · noun
nutriment
🥦 養 (nourish) + 分 (portion) = the portion that nourishes you
養 means to nurture or raise, and 分 means part or share. Together, 養分 is the share of substance that feeds growth, the nutrient.
分 — knife 刀 + eight 八 (split apart)
分 originally depicted a knife (刀) cutting something into two parts, shown by 八 above (which itself meant 'divide'). The core sense is 'to divide' or 'split', from which extended meanings like 'portion', 'minute', and 'part' developed. Pronounced fèn, it carries the sense of an allotted share.
