The modern Malayalam script of Kerala is a direct descendant of the Grantha script. The Southeast Asian and Indonesian scripts such as Thai and Javanese respectively, as well as South Asian Tigalari and Sinhala scripts are derived or closely related to the Grantha through the early Pallava script.

Old Tamil is the period of the Tamil language spanning the 450 BCE to the 7th CE. Prior to Old Tamil, the period of Tamil linguistic development is termed as Pre Tamil or Ancient Tamil. Post Old Tamil, Tamil becomes Middle Tamil. The earliest records in Old Tamil are inscriptions from between the 3rd and 1st century BCE in caves and on pottery. These inscriptions are written in a variant of the Brahmi script called Tamil Brahmi. The earliest long text in Old Tamil is the Tolkāppiyam, an early work on Tamil grammar and poetics, whose oldest layers could be as old as the mid 2nd century BCE. Old Tamil preserved many features of Proto-Dravidian, the earliest reconstructed form of the Dravidian including inventory of consonants, the syllable structure, and various grammatical features.

Periyar E. V. Ramasamy was a Dravidian social reformer and politician from India, who founded the Self-Respect Movement and Dravidar Kazhagam. Periyar placed great importance on the Tamil language for its benefit and upliftment to the Tamil people and advocated for its preservation. In the wake of the imposition of Hindi throughout the Indian sub-continent and in Tamil Nadu, Periyar stated that "the love of one's tongue is the foremost of all loves that are required of the people born in our land. He said that has no love for his tongue has no love for his land. A nation functions on the basis for the love of one's language. So it is my prayer that Tamils love for their tongue should grow. I affirm again and again that love of the mother-tongue is a must for those born in Tamil Nadu. The Bengalis love Bengali. The Maharashtrians love for the Marathi language. The Andhras love the Telugu language. But the Tamils have no love for the Tamil-tongue. The Tamils will never progress unless they bestow love on their mother-tongue. If I love Tamil, it is not merely because it is the mother-tongue or the language of the Tamil Nadu State. Nor am I attached to Tamil by reason of its uniqueness or its antiquity. If I love Tamil, it is because I am aware of the advantages I expect through it and the measure of loss that will occur by the absence of it".
