I share here some of my thoughts.
The hegemonic policy of Assamese language and hurdles in executive levels are there if we see from stat perspective. The Assamese language itself is facing challenges as it has dipped below 50 per cent mark in Assam. Instead of Assamese language, there is a rise of Bengali and Hindi speakers.
In this backdrop, Assamese language nataionlist and radical supporters will not allow space for open growth of ethnic minorities' languages. This would mean downsizing of potential speakers of Assamese language if tribal languages grow. Being an indigenous but minority group, Misings would always pick up the Assamese language for education and jobs to secure state benefits unless their mother tongue too give them such potential.
Comparatively, the progress of Mising language cannot be compared with the progress of Bodo language. Bodos have not achieved the current status by sitting simply idle. They have waged a long struggle since 1960s even before our Mising Sahitya Sabha or Agon Kébang was formed. They have taken decisive and far reaching step by compromising their Roman script with Devnagari script to stick to the line of unwritten central govt policy. In fact, this has paved the way for constitutional inclusion of Bodo language.
Mising are democratic who believes in non-violent tactics in pursuing their political, socio+economic or cultural goals. The historicity and ethnic assertion is lesser among Misings since they cannot resonate with solid statecraft or being defeated or dethrone by some other monarch. The Bodos instead have glorious past in the sphere of statecraft.
Emerging middle class of Misings are receptive to Assamese or any other languages whichever benefit them. There is no radical nationalism in the name of language among educted Misings. Instead most Misings are comfortable in Assamese language than their mother tongue after they move to urban areas. In fact, the children are not encourage to learn their mother tongue among middle class. Assamese (or even Hindi, of late) becomes a language of symbolic aristocracy when they interact with fellowmen in village.
Polarization among the political class and middle class organization elites. Politic class of the Misings doesn't have the same priority for langauge and literature. Except the literary body and the apex body, even the banner, poster and statement are not circulated in their mother tongue text.
Of course, to some extent, the adoption of script and reading method is also creating a rift among Misings.
The middle class Mising does not dedicate even the least needful for the development of their literature. Writings in mother tongue among middle class is difficult to find.
Of course, there is a good number of singers and actors among Misings. Youth are connected through folk songs and oi nitom, movies, romantic and even rap songs in mother tongue shared in cyberspace. The silver lining is seen in the cultural dimensions but not in literature.
Dr. Nahendra Padun, linguist and stalwart of Mising language has argued that younger generation should shoulder the responsibility to develop the language and enrich the literature.
