Yi Syllable Mgu

In kaomoji, ꉂ signals laughter; in Nuosu, it is a real syllable.

In a Japanese-style face such as ꉂ(ˊᗜˋ*), ꉂ is the laughter cue; doubling it in ꉂꉂ makes the reaction read as hearty or louder. In Nuosu, mgu is a syllable glossed “like; love.” The same glyph also appears in Nuosu grammar as a sentence-final evidential marking the proposition as the speaker’s own idea.

Do not project the internet laugh back onto Yi history. There is no defensible single inventor in the evidence: the tradition’s origins are debated, and the earliest reliably dated example is a bronze-bell inscription from the 15th century. Traditional Yi writing was copied by bimo priests for religious, magical, medical, genealogical, and historical texts. The modern Liangshan standard was devised in 1974 and officially promulgated in 1980; later literacy materials use it for everyday learning. Related Yi script traditions vary greatly; these are not Han Chinese characters in another font.

Why does ꉂ appear in laughter faces?

It is a borrowed visual laughter cue, not an emoji face.

As of 2026, Japanese kaomoji collections list ꉂ and ꉂꉂ before open-mouth faces as hearty or loud laughter. This is a borrowed online convention: the face carries the expression, while ꉂ acts as a visual burst of laughter. A Nuosu reader may instead process the glyph as language, so the surrounding face is what settles the online reading.
