Marathi is one of several languages that further descend from Maharashtri Prakrit. Further change led to the Apabhraṃśa languages like Old Marathi, however, this is challenged by Bloch (1970), who states that Apabhraṃśa was formed after Marathi had already separated from the Middle Indian dialect. The earliest example of Maharashtri as a separate language dates to approximately 3rd century BCE: a stone inscription found in a cave at Naneghat, Junnar in Pune district had been written in Maharashtri using Brahmi script. A committee appointed by the Maharashtra State Government to get the Classical status for Marathi has claimed that Marathi existed at least 2300 years ago alongside Sanskrit as a sister language. Marathi, a derivative of Maharashtri, is probably first attested in a 739 CE copper-plate inscription found in Satara After 1187 CE, the use of Marathi grew substantially in the inscriptions of the Seuna (Yadava) kings, who earlier used Kannada and Sanskrit in their inscriptions. Marathi became the dominant language of epigraphy during the last half century of the dynasty's rule (14th century), and may have been a result of the Yadava attempts to connect with their Marathi-speaking subjects and to distinguish themselves from the Kannada-speaking Hoysalas.
