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.
寸 — hand 又 + indicator dot 一
寸 originally depicted a hand (又) with a small mark indicating the pulse point about one inch below the wrist. It came to mean 'inch,' a traditional Chinese unit of length, and by extension 'a tiny amount.' It often appears as a component suggesting hand actions or measurement.
