Sanskrit is the most commonly used language in Hindu texts

Hindu texts, which have a rich legacy of philosophical and theological writings as well as works of poetry, music, drama, science, and other genres, have traditionally been written in Sanskrit. One of the largest collections of old manuscripts is written in it the most often. The earliest known Sanskrit writings date back to the first century BCE and include the Ghosundi-Hathibada and the Dhana Inscription from Ayodhya (Chittorgarh).

Sanskrit has been the language for some of the main literary works and theology of heterodox schools of Indian philosophies like Buddhism and Jainism, despite being founded and cultivated by academics of orthodox schools of Hinduism. Ancient Indians began speculating about "the nature and function of language," the relationship between words and their meanings in the context of a community of speakers, whether this relationship is objective or subjective, discovered or is created, how people learn and relate to the world around them through language, and about the limits of language, thanks to the structure and capabilities of Classical Sanskrit. They discussed the function of language, the ontological status of creating word-images through sound, and the necessity of rules in order for a community of speakers to communicate and comprehend significant ideas from one another despite being geographically or temporally separated.
