According to Arthur Coke Burnell, one form of the Grantha alphabet, originally used in the Chola dynasty, was imported into the southwest coast of India in the 8th or 9th century, which was then modified in course of time in this secluded area, where communication with the east coast was very limited. It later evolved into Tigalari-Malayalam script was used by the Malayali, Havyaka Brahmins and Tulu Brahmin people, but was originally only applied to write Sanskrit. This script split into two scripts: Tigalari and Malayalam. While Malayalam script was extended and modified to write vernacular language Malayalam, the Tigalari was written for Sanskrit only. In Malabar, this writing system was termed Arya-eluttu (, "Ārya eḻuttŭ"), meaning “Arya writing” (Sanskrit is Indo-Aryan language while Malayalam is a Dravidian language).
