Kirat Rai

Kirat Rai (also called Rai, Khambu Rai, Rai Barṇamālā and Kirat Khambu Rai) is a left-to-right abugida (a type of segmental writing system), based on the Sumhung Lipi of 1920s, used to write the Bantawa language in the Indian state of Sikkim. Kirat Rai is composed of 31 primary characters, including seven vowels (and seven related vowel diacritics), one of which (/a/) is inherent in all consonants, 31 consonants, a virama to cancel the inherent vowel, and a vowel carrier to be used in combination with the vowel diacritics for writing word-initial vowels.
