Yi Radical Yo

꒝ is an index sign used to sort Liangshan Yi syllable characters.

A radical is a lookup mark for a stroke shape shared by a group of syllable signs. Dictionaries sort the signs by these marks, which helps readers locate an entry.

why was yi radical yo made?

The radical system helps readers find characters in Yi dictionaries.

Traditional Yi writing was not one uniform script: local forms differed in their signs and writing directions. It was used for religious, magical, medical, and family-history texts passed down by village priests. A traditional account credits Aki with devising a script during the Tang dynasty (618–907); the oldest surviving dated monument is a bronze bell inscription from 1485.

To improve literacy in the Liangshan variety of Yi, a standardized script was devised in 1974 and officially promulgated in 1980. This system writes spoken syllables; radicals like ꒝ group its syllable signs by shared strokes for dictionary lookup.

is yi radical yo a syllable?

No. ꒝ is a radical for lookup, not a syllable sign.

The label “yo” comes from the Yi syllable sign closest to ꒝ in shape. That romanized label identifies the model; it does not give the radical a syllable reading of its own.
