From the top of my head as a very lay person, I can count several languages that are not only completely distinct but also completely alien to me as a Hindi speaker: Marathi, Bengali, Oriya, Assamese, Kannada, Tamil, Telugu, Malyalam. These are major languages and form the basis of a lot of state boundaries.
