Writing and language

Cyr-SD — Cyrillic Sindhi

About the project

Research projectStatus: in developmentPeriod: 2024–2027

A project to develop a Cyrillic writing system and alphabet for the Sindhi language. The aim is not to transliterate the existing Perso-Arabic script, but to create a systematically designed Cyrillic alphabet capable of representing Sindhi phonological and graphemic distinctions.

Cyr-SD is based on a compact visual grammar: basic Cyrillic letters are supplemented with systematic graphic operators for the consistent representation of retroflex, aspirated, and implosive consonants. The project includes formalizing correspondences with the traditional Sindhi alphabet, developing a machine-readable Unicode representation, and testing the reversibility of conversions.

The project also includes Cyr-SD-L, a lossless layer for unambiguous, machine-reversible representation of source text while preserving distinctions in the original script. A separate readable/phonemic layer, Cyr-SD-R, is also planned.
