rin, 1/10 sen, 1/10 bu
厘 centers on a tiny unit of measurement: one rin, which is one-tenth of a sen or one-tenth of a bu. The meaning is purely a fractional monetary or measurement unit.
厘 is a relatively modern character created in Japan to represent the fractional unit rin. It combines 厂 (cliff) with 里 (village), but the choice of components is likely phonetic rather than semantic.
Imagine a tiny village (里) tucked under a cliff (厂). The village is so small it represents just a fraction of a larger town—like one rin, a tiny unit.
For リン, picture a tiny ring (リン) used as a fractional weight: ring -> リン, and the ring is so light it measures just one rin.
