Lepcha Letter Tta

It marks a retroflex t without an extra puff of breath. In Lepcha, that means pronouncing t with the tongue curled back. The ordinary t-like letter is ᰊ; ᱎ marks the same curled-back position with an added puff of breath. ᱍ contributes a consonant sound inside a Lepcha syllable.

Why does Lepcha tta have two spellings?

The older spelling used a consonant sequence; ᱍ gives that sound one letter. Lepcha retroflex sounds occur in words borrowed from Tibetan. Before dedicated letters were introduced, the sound could be spelled ᰀ᰷ᰥ: ᰀ is Lepcha ka, ᰷ is a modifying mark called nukta, and ᰥ is a ra sign used after a consonant. The sequence represented the same sound that ᱍ writes with one letter.

The Lepcha script developed from Tibetan writing, adapting its letter forms and adding signs for Lepcha consonants at the ends of syllables. The Lepcha literary tradition is placed in the 18th century; the oldest identified handwritten materials date from the second half of the 19th century. Lepcha tradition credits Thikúng Mensalóng with the script, while another account connects its development to the reign of Sikkim king Chakdor Namgyal.

Lepcha manuscripts include adapted Tibetan Buddhist works alongside texts from Lepcha religious traditions. The 2025–2026 syllabus of India's Central Board of Secondary Education (CBSE) includes Lepcha for grades 9 and 10.
