It is suggested that loss of the neuter gender did not occur until the transition to NIA. During this process, most of the neuter nouns became masculine, while several became feminine. For example, the neuter "aggi" "fire" in Prakrit morphed into the feminine "āg" in Hindi, and "jag" in Romani. The parallels in grammatical gender evolution between Romani and other NIA languages have additionally been cited as indications that the forerunner of Romani remained on the Indian subcontinent until a later period, possibly as late as the tenth century.
