What ꒐ means
It helps find Yi characters in dictionaries. A radical is a lookup mark based on a stroke shared by a group of characters.
Before modern standardization, local Yi script forms varied. Village priests passed on religious, medical, and genealogical texts within their communities. The earliest surviving dated Yi inscription is on a bronze bell from 1485. The standardized Liangshan Yi script became a syllabary in 1974 (each sign represents a syllable) and was officially promulgated in 1980; it represents Liangshan, not every Yi variety.
