The Central government's Linguistics Expert Committee recommended tweaks in the criteria for granting classical status.
Current Status and Demands:
Currently, India has six classical languages: Tamil (declared in 2004), Sanskrit (2005), Kannada (2008), Telugu (2008), Malayalam (2013), and Odia (2014).
Current Criteria for Classical Language Status:
High antiquity of its early texts/recorded history over a period of 1500-2000 years;
A body of ancient literature/texts, which is considered a valuable heritage by generations of speakers
The literary tradition be original and not borrowed from another speech community
The classical language and literature being distinct from modern, there may also be a discontinuity between the classical language and its later forms or its offshoots.
Benefits: Designated classical languages receive benefits such as
international awards for scholars
establishment of centers of excellence
creation of professional chairs in universities
There have been demands from various states and literary circles, including Maharashtra, for classical status for languages like Marathi, Bengali, Assamese, and Maithili.
The demand for Marathi has been pending for over a decade despite multiple assurances from the Central government. In 2014, a committee chaired by Ranganath Pathare concluded that Marathi meets all criteria for classical language status.
