附

A phono-semantic compound consists of:

阜 (mound; hill) — semantic component, often associated with places, structures, or physical attachment;

付 (to hand over) — phonetic component, supplies pronunciation "bu" and supports the meaning of “handing over/attaching.

The original sense suggests "something placed against or attached to a mound or structure," which later generalized into the meaning “to attach” or “to adhere.”

According to the Shuowen Jiezi (説文解字) the original meaning was “small earthen mound.” Over time, this sense was lost, and the meaning shifted to “attach, join, rely on.”

Semantic development:

- physical attachment;

- adding or appending;

- relying or depending upon;

- following or aligning with (political/social).
