The Grantha alphabet is a descendent of the Brahmi alphabet and started to emerge during the 5th century AD. Most of the alphabets of southern India evolved from Grantha, and it also influenced the Sinhala and Thai alphabets.
The Grantha alphabet has traditional been used by Tamil speakers to write Sanskrit and is still used in traditional vedic schools (patasalas)
