Yi Syllable Su

ꌠ writes the Nuosu syllable su³³.

Nuosu is a Yi language. In its standardized script, ꌠ represents a syllable romanized as su³³, roughly like “soo” with level pitch. It functions as a grammatical particle, not as a word with one fixed English gloss.

After a verb, adjective, or clause, it can make the preceding material noun-like, including a relative expression; in a noun phrase, it can contribute to a definite reading. The surrounding grammar supplies the translation.

Why was the Yi script made?

To make a consistent written standard for Nuosu.

Traditional Yi writing grew through several related local traditions rather than one uniform invention. Village priests used it to pass down religious, magical, medical, and family-history texts. The earliest surviving Yi writing that can be dated securely is a bronze-bell inscription from 1485; that date does not establish when ꌠ itself first appeared.

The modern standardized Liangshan form was devised in 1974 and officially promulgated in 1980. It addressed varying local glyph forms and inconsistent representation of the modern language’s sounds. The standard aimed to support literacy and is used in education, reference works, newspapers, public signs, and subtitles.

Nuosu, Nasu, Nisu, Sani, and Azhe writing traditions have related histories but different sign inventories and shapes. Traditional Yi writing developed as its own script, separate from Chinese Han writing.
