Can Tani Language become a lingua franca of Tani Group?

But what is Tani Language? Do we really have a language called Tani Language? Is it the language spoken by the Apatani’s or the Nyishi’s or the Adi’s or any other tribe of Tani group? But then, don’t their languages differ not to be quite intelligible enough amongst themselves? So, when Tani Federation Forum (TTF) based at Guwahati called for making Tani Language as lingua franca of Tani group, I wondered which Tani Language they were referring to.

Unification bid by the Tanis

ITANAGAR, June 18: The Tanis of Arunachal Pradesh and Asom irrespective of their boundaries, religion and political identities have decided to unify and unite in their greater interest.

This was the unanimous decision taken at the first plenary session of Guwahati-based Tani Federation Forum (TFF) held at North Lakhimpur yesterday with the participation of representatives from both states. Former Arunachal Minister Tadar Taniang was the chief guest.

Though the tribe society was passing through a transition, the session opposed the imposition of Sanskrit language and called for its replacement by Tani language, which could serve as lingua-franca and integrate the entire tribe living in various part of the North East Region, according to TFF release.

Though, their call for unification of Tani groups is quite commendable yet I couldn’t understand their call for making Tani Language a lingua franca of Tani groups, when there is no common language amongst Tani group as Tani Language. Or do we have?

BTW, what is this TTF? Who are they? Why are they based at Guwahati when majority of Tani groups are settled at Arunachal Pradesh?
