The term “Bihari language” doesn’t refer to a single specific language, but rather it is a collective term used to describe a group of languages spoken in the Indian state of Bihar and surrounding regions. These languages are part of the Indo-Aryan language family, which is also the family of languages that includes Hindi, Bengali, Punjabi, and others.

Some of the languages that fall under the category of Bihari languages include Magahi, Bhojpuri, Maithili, Angika, and others. Among these, Bhojpuri and Maithili are the most widely spoken.

1. Bhojpuri: Bhojpuri is spoken primarily in the northern and eastern regions of India, especially in Bihar, Jharkhand, and parts of Uttar Pradesh. It has a significant number of speakers and has gained recognition through music and film industries.

2. Maithili: Maithili is spoken mainly in the northeastern part of Bihar and in some regions of Nepal. It is one of the 22 scheduled languages of India and has a rich literary tradition.

3. Magahi: Spoken in parts of Bihar, Jharkhand, and some adjoining areas. Magahi is known for its distinct phonological and grammatical features.

4. Angika: This language is spoken in parts of Bihar and Jharkhand. It is closely related to Maithili and Bhojpuri.

5. Bajjika: This is another Bihari language spoken in some regions of Bihar.

It’s important to note that these languages have their own distinct grammar, vocabulary, and phonological systems. While Hindi is the official language of the Indian government, many people in Bihar and surrounding regions speak one or more of these Bihari languages in their daily lives.
