配分

distribution
配 — wine vessel 酉 + self 己
Originally depicted a person 己 beside a wine jar 酉, suggesting matching or distributing wine at ceremonies. From this came the meaning 'to pair, match, distribute,' and later 'to deserve' or 'to mix/compound.' The 酉 component gives the wine-related semantic root, while 己 contributes phonetically.
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.
