 Criteria for Classical Languages in India:

The government of India currently follows the following criteria to determine the eligibility of language to be considered for classification as “classical language”:
- 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.
