The Central Indo-Aryan languages or Hindi languages are a group of related language varieties Spoken across North India and Central India. These language varieties form the central part of the Indo-Aryan language family, itself a part of the Indo-European language family. They historically form a dialect continuum that descends from the Middle Prakrits. Located in the Hindi Belt, the Central Zone includes the Dehlavi (Delhi) dialect (one of several called 'Khariboli') of the Hindustani language, The lingua franca of Northern India that is the basis of the Modern Standard Hindi and Modern Standard Urdu literary standards. In regards to the Indo-Aryan language family, the coherence of this language group depends on the classification being used; here only Eastern and Western Hindi will be considered.
If there can be considered a consensus within the dialectology of Hindi proper, it is that it can be split into two sets of dialects: Western and Eastern Hindi. Western Hindi evolved from the Apabhraṃśa form of Shauraseni Prakrit, Eastern Hindi from Ardhamagadhi Prakrit.
This analysis excludes varieties sometimes claimed for Hindi for cultural reasons, such as Bihari, Rajasthani, and Pahari.
Romani, Domari, Lomavren, and Seb Seliyer (or at least their ancestors) appear to be Central Zone languages that migrated to the Middle East and Europe ca. 500–1000 CE in three distinct waves. Parya is a Central Zone language of Central Asia.
