About

is a phono-semantic compound: the radical on the left indicates a worm, bug, or creeping creature, while (shàn) on the right provides the pronunciation. Although typically means "good", it acts here solely as a phonetic. The character denotes an earthworm and appears almost exclusively in the compound 蚯蟮 (qiūshàn), a dialectal or alternative written form of the standard 蚯蚓 (qiūyǐn).
