The study, states that languages like Reli became extinct due to the threats to their livelihood and pressure on the tribes to mingle with the society. Most of the languages that have become extinct were spoken either by the coastal or the nomadic tribes, the report states.
As these tribes tried to mingle with the mainstream society, they gave up on their cultural and linguistic identity. However their tribal counterparts are doing relatively well in the northern part of the state where they face lesser threat.
Some of the languages on the verge of extinction are Gutaba Gadaba, Manda, Mannadona and Gormati of the Banjaras.
The report also mentions that certain scheduled languages that are spoken in the pockets of a state is relatively different from those spoke in the parent state, such as adivasi oriya spoken in AP is different from Oriya.
The survey was conducted with more than 3,000 volunteers that spanned across four year.
