पडोसी भाषा-समूह
There are several other languages spoken around Maithili and Magahi and Bhojpuri and the superposed variety of Hindi (of a deviant kind, of course) are the languages also found within the Maithili-speaking districts. Bihar being a multi-lingual state with great internal as well as external mobility, one can find also a number of Nepali and Bengali speakers in the area where Maithils live predominantly. In addition, since Maithili speakers are found in good numbers in the Jharkhand region too, one has to take it that Oraon, Mundari, Ho, Bihar, Darbhanga, Santali and a number of the smaller Austric language speakers too co-exist with the speakers of Maithili. At times, and more predominantly among the twice-born but non-Brahmin castes of Maithili-speakers, the contact with Bhojpuri, Magahi and Hindi speakers are also established through inter-marriages. And, of course, Hindi being the language of education and instruction, and Urdu being the language of a sizable population are also available in Mithila.
