What ꒘ means
It marks a search category for full Yi syllables.
A Yi radical-stroke index groups signs by component, then sorts them by remaining strokes. The name’s “Mi” labels a reference syllable shape, not a word meaning.
How did Yi writing develop?
Yi writing grew through regional traditions.
The record includes stone inscriptions from the thirteenth century, a bronze-bell inscription about 1485, and paper or sheepskin texts around 1500. Before standardization, local ritual experts kept Yi texts on religious, magical, medical, and genealogical knowledge. Standardized Liangshan Yi entered official, newspaper, and literary publishing in the 1950s–1980s.
