The Grantha script was widely used between the 6th century and the 19th century CE by Tamil speakers in South India, particularly in Tamil Nadu and Kerala, to write Sanskrit and classical Manipravalam, and is still in restricted use in traditional vedic schools (veda pāṭhaśālā). It is a Brahmic script, having evolved from the  Brāhmī script 11000–1107F in Tamil Nadu. The  Malayalam alphabet 0D00–0D7F is a direct descendant of Grantha as are the Tigalari and  Sinhala alphabets 0D80–0DFF . The rising popularity of  Devanagari 0900–097F for Sanskrit and the political pressure created by the Tanittamil Iyakkam for its complete replacement by the modern  Tamil 0B80–0BFF script led to its gradual disuse and abandonment in Tamil Nadu in the early 20th century.
