to rob, to collect, to edit, bamboo basket
篹 is a rare kanji with several distinct meanings that do not share one clear center: it can mean to rob or steal, to collect or compile, to edit, or a bamboo basket. The connection between these senses is unclear, and the kanji is best treated as having multiple unrelated meanings.
The historical development of 篹 is uncertain. It visually contains 竹 (bamboo) on top and 㔾 at the bottom, but the exact origin and how the meanings relate to these components are unclear.
Imagine a bamboo basket (竹) being used to collect things, but someone tries to rob it. The basket's contents are being edited—some items taken, some left.
For サン, picture a bamboo basket sitting in the sun: sun -> サン, and the basket is used to collect or rob things under the sunlight.
