"All Tamil speakers, including the uneducated, use two varieties of the language which only roughly correspond to the difference between literary and spoken Tamil. A high status variety is used in most writing, the media--including radio and television broadcasts--political speeches and other similar occasions. In contrast, a low status variety is used in every day discourse and conversations. It is also used in film and some authors of fiction use the variety as do some politicians and lecturers to create solidarity, or enhance intimacy, with their audiences."
