variant form of this script, Kolezhuthu, was used until about the 19th century mainly in the Malabar-Cochin area. Vatteluttu was in general use, but was not suitable for literature where many Sanskrit words were used. Like Tamil-Brahmi, it was originally used to write Tamil, and as such, did not have letters for voiced or aspirated consonants used in Sanskrit but not used in Tamil. For this reason, Vatteluttu and the Grantha alphabet were sometimes mixed, as in the Manipravalam. One of the oldest examples of the Manipravalam literature, Vaishikatantram (, Vaiśikatantram), dates back to the 12th century, where the earliest form of the Malayalam script was used, which seems to have been systematized to some extent by the first half of the 13th century. Another variant form, Malayanma, was used in the south of Thiruvananthapuram. By the 19th century, old scripts like Kolezhuthu had been supplanted by Arya-eluttu – that is the current Malayalam script. Nowadays, it is widely used in the press of the Malayali population in Kerala. Grantha 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). Karshoni Suriyani Malayalam (സുറിയാനി മലയാളം, ܣܘܪܝܢܝ ܡܠܝܠܡ), also known as Karshoni, Syro-Malabarica or Syriac Malayalam, is a version of Malayalam written in a variant form of the Syriac alphabet which was popular among the Saint Thomas Christians (also known as Syrian Christians or Nasranis) of Kerala in India. It uses Malayalam grammar, the Maḏnḥāyā or "Eastern" Syriac script with special orthographic features, and vocabulary from Malayalam and East Syriac. This originated in the South Indian region of the Malabar Coast (modern-day Kerala). Until the 20th century, the script was widely used by Syrian Christians in Kerala.
