Tulu language is one of the five Dravidian languages of South India (Pancha-Bhasha, others are Tamil, Telugu, Kannada and Malayalam). The four major languages spoken today are dominantly spoken in their respective states (Tamilnadu, Andhra Pradesh, Karnataka and Kerala), whereas Tulu is spoken in a small niche, mainly in coastal Karnataka and Northern Kerala (Kasaragod district). About 2.5 million people speak Tulu and call it their mother tongue. Tulunadu is a region where many languages are spoken. While Kannada is the official state language, different ethnic communities in Tulu Nadu speak different languages. Tulu, derived from proto-Dravidian is the predominant language spoken by Hindus of various castes and by the Jains of Tulu Nadu. Konkanasthas and Catholics speak two variants of Konkani. Muslims speak a language of their own that is derived from Tulu as well as Malayalam.
There are about 24 Dravidian languages recognized by linguists. Of these the five languages in the South developed into major languages. Tulu is the only developed language that has not received the recognition it is due. However, Tulu language with its near extinct script has been generating much enthusiasm amongst the linguists, as it is now believed to be one of the oldest Dravidian languages.
The Tulu language has lost its prominence as a major language. Lack of serious literature in Tulu language has also hampered its claim as a language to be taught in educational institutes. Though it is certain that most of the literature has been lost because of difficulties in preserving palm leaf scrolls, the earliest literature available is from the 15th century. This indeed is a much later work than the language itself, which is thousands of years old. There was also some confusion regarding the script of Tulu language, which closely resembles Malayalam. It was thought that priests from Tulu Nadu went south to Kerala to perform and learn Agama Sastra rituals, where they jotted notes borrowing the Malayalam alphabets. This was the prevailing thought of many researches although now there is a consensus that Tulu language possessed its own script before Malayalam script existed. Perhaps the reciprocal is true that the Malayalam script developed from Tulu script as the language predates Malayalam by more than a thousand years. The priests who went south are now credited with carrying mantras written in Tulu script to Kerala. Like Tamil and Malayalam, Tulu script is derived from the Grantha script.
The script used by the migrating Tulu priests in Kerala to write Vedas and mantras around 11-12th century is popularly known as the Tulu Script. As this script form is popular in both Tulu Nadu and Kerala, it’s called Tulu-Malayalam script. This Tulu-Malayalam script became Malayalam script in Kerala and Tulu script in Tulunadu. These two scripts share much similarities because they originated from same parent script
