Eastern Indo-Aryan languages in the context of "Rohingya language"

Bishnupriya Manipuri, also known as Bishnupriya Meitei or simply as Bishnupriya, is an Indo-Aryan lect belonging to the Bengali–Assamese linguistic sub-branch. It is a creole of the Bengali language and the Meitei language (also called Manipuri language) and still retains its pre-Bengali features.

It is spoken in parts of the Indian states of Assam, Tripura, and Manipur, as well as in the Sylhet Division of Bangladesh, and uses the Bengali-Assamese script as its writing system. Bishnupriya Manipuri is a member of the Eastern Indo-Aryan languages and evolved from Magadhi Prakrit; hence its origin is associated with the Magadha realm.

Chakma (/ˈtʃɑːkmə/; autonym: 𑄌𑄋𑄴𑄟𑄳𑄦 𑄞𑄌𑄴) is an Eastern Indo-Aryan language in the branch of the Indo-Iranian languages in the Indo-European language family, whose speakers are known as the Chakma or the Daingnet people. It has nearly 1 million speakers, with 60% residing in the Chittagong Hill Tracts (CHT) in Bangladesh and 35% spread across Arunachal Pradesh, Assam, Mizoram and Tripura in India. The remaining 5% live in Myanmar. The language has it own script, the Chakma script or the ajhapat (𑄌𑄋𑄴𑄟𑄳𑄦 𑄃𑄧𑄏𑄛𑄖𑄴), which is an abugida similar other South-east Asian scripts. It is mutually intelligible with the Chittagonian language.

Similarities of the Chakma language with Sanskrit, Maghadi Prakrit and with Pali is visible referring it to be a classical language. This suggests that the Chakmas have been present in the Indian subcontinent since ancient times. Cultural exchanges with neighboring communities have led to the adoption of Indo-Aryan and Arakanese terms. Studies suggest that the language may have originally been a Tibeto-Burman language before transitioning into an Indic language. However, there are abundant of vocabularies used in the Chakma language that do belong neither to Indo-Aryan nor Tibeto-Burman linguistic group, likely originating from their ancestral language. Historically, a Mongoloid group that settled in the Himalayan foothills spoke a Tibetan-related language but gradually incorporated Aryan vocabulary.

The Hindi Belt, also known as the Hindi Heartland, the Hindi-speaking states, and sometimes more broadly referred to as the Hindi–Urdu Belt or Hindustani Belt, is a linguistic region encompassing parts of northern, central, eastern, and western India where various Northern, Central, Eastern and Western Indo-Aryan languages are spoken, which in a broader sense is termed as Hindi languages, with Modern Standard Hindi (a Sanskritised version, based on Khari Boli) serving as the lingua franca of the region. This belt includes all the Indian states whose official language is Modern Standard Hindi.

The term "Hindi Belt" is sometimes also used to refer to the nine Indian states whose official language is Modern Standard Hindi, namely Bihar, Chhattisgarh, Haryana, Himachal Pradesh, Jharkhand, Madhya Pradesh, Rajasthan, Uttar Pradesh and Uttarakhand, as well as to the union territory of Chandigarh and the National Capital Territory of Delhi.

The Bengali-Assamese languages (also Gauda–Kamarupa languages) is a grouping of several languages in the eastern Indian subcontinent. This group belongs to the Eastern zone of Indo-Aryan languages. The languages in this group, according to Glottolog, include Assamese, Bengali, Bishnupriya, Chakma, Chittagonian, Hajong, Kharia Thar, Kurmukar, Mal Paharia, Noakhali, Rajbangshi, Rohingya, Sylheti, Tangchangya, Thar and Surjapuri.

The phonology of Bengali, like that of its neighbouring Eastern Indo-Aryan languages, is characterised by a wide variety of diphthongs and inherent back vowels (both /o/ and /ɔ/).

Abahaṭ‌ṭha, Abahatta or Avahaṭṭha (Sanskrit apabhraṣṭa 'corrupted', related to apabhraṃśa) is a stage in the evolution of the Eastern group of the Indo-Aryan languages. This group consists of languages such as Assamese, Bengali, Bhojpuri, Magahi, Maithili, and Odia. Abahatta is considered to follow the Apabhraṃśa stage—i.e. those Apabhraṃśas derived from Magadhi Prakrit.

After different business and trading classes, including the Jains, rose in power and influence at the end of the ninth century CE, the widespread speaking of classical Sanskrit waned. Apabhransa and Abahatta thus became very popular, especially amongst common people, functioning as a lingua franca throughout the north of the Indian subcontinent.
