Chaklader (1981) argues for adopting a definition of minority languages at the state level. A ‘minority language’, in the most straightforward sense, is simply one language spoken by less than 50 percent of a population within a specific geographic region which is different from the language of the majority community and the language of the state. The crucial point is the proportion of speaker population in the given region or country. In other words, a minority language might be only a minority language in this specific region, but a majority language in other region (Grenoble, 2014). For example, Spanish is the majority language in a group of south American countries, however, it is a minority language in the USA in general. Mongolian, is also an example of this kind of minority language.
