Apart from it in the foothill of Himalaya in the north-eastern part of Bihar in district Kishanganj the language spoken is Rajbangshi.
The relationship of Maithili community with Bhojpuri and Magahi communities – the immediate neighbors have been neither very pleasant nor very hostile. Maithili has been the only one among them which has been trying to constantly deny superimposition of Hindi over her identity. The other two have given up their claims and have resigned to accept the status of dialects of Hindi.
It goes without saying that the relationship of Maithili and Hindi have been most complicated. While almost all Maithils have accepted Hindi as a language of formal occasions, the retention of Maithili for cultural, social, familial as well as literary purposes have also been more or less steady. The trend among the youngest generation to use Maithili in lesser and lesser occasions should be viewed in the context of the same thing happening among Hindi, Telugu or Marathi speakers who are tilting towards use of English rather than their mother tongue.
Vajjika region broadly comprises the districts of Muzaffarpur,Samastipur, Vaishali, Sitamarhi, Champaran and Sheohar, in the eastern part of India. Vajjika is the mother-tongue of people of this area.
