The Romani language is usually included in the Western Indo-Aryan languages. Romani varieties, which are mainly spoken throughout Europe, are noted for their relatively conservative nature; maintaining the Middle Indo-Aryan present-tense person concord markers, alongside consonantal endings for nominal case. Indeed, these features are no longer evident in most other modern Central Indo-Aryan languages. Moreover, Romani shares an innovative pattern of past-tense person, which corresponds to Dardic languages, such as Kashmiri and Shina. This is believed to be further indication that proto-Romani speakers were originally situated in central regions of the subcontinent, before migrating to northwestern regions. However, there are no known historical sources regarding the development of the Romani language specifically within India.
