Pronounced su guǒ (falling tone) in Tang Yun, and sǔn guǒ (falling tone) in Jiyun, sounding similar to "suǒ". Explained in Shuowen Jiezi as "shòu yě" (obstinate). In Yupian, it is explained as gāo suǒ (fatty secretion). Some also suggest it refers to small shells. All meanings related to small pieces or fragments originate from this. The character "䐝" derives its sound from "锁" and should share a similar meaning with "脞" (fragmented). Additionally, pronounced xiān wò (falling tone) in Guangyun, and sū wò (falling tone) in Jiyun, sounding similar to "sù". The meaning is the same.
