Limbu letter Sha

It starts a syllable with “sh” and includes a short “o” vowel.

The name “sha” refers to the hissing sound at the start of English “ship,” written /ʃ/ by linguists. Limbu consonants carry an inherent short open “o” vowel, usually transcribed [ɔ]. So ᤙ on its own includes that vowel; add a vowel sign, a mark attached to the consonant, when the word needs a different one. Read it as part of the full Limbu syllable.

Where does the Limbu script come from?

A catalogued alphabet book reaches back to c. 1730 or earlier.

A catalogued Limbu alphabet book reaches c. 1730 or earlier and is associated with Sirijanga. A separate traditional origin story traces an ancestor of the script to a ruler in the ninth century; that is a provenance story, not the same kind of evidence as a manuscript.

Sirijanga, a Limbu culture hero, is credited with inventing the script and is also associated with its later revival, teaching, and literature. Limbu is classed among Brahmi-derived scripts, a family that grew from the older Brahmi writing system. Some accounts connect its design to Róng (Lepcha), a separate script for the Lepcha language; Lepcha itself descends from Tibetan. These are whole-script histories, not evidence that ᤙ itself descends from a Tibetan letter.

How has the script been used?

It spread from revival work into books, classrooms, newspapers, and ritual writing.

Limbu writing appears in songs, poetry, novels, histories, teaching materials, newspapers, textbooks, and ritual publications.

When local printing was technically unavailable, some Limbu works appeared in Devanagari, a script used for Nepali and several other languages. Publication in the Limbu script expanded after 1990. That change is about where the language was written, not the sound of ᤙ: it remains a syllable-onset letter.
