Traditions which reject Vedic authority also reject the primacy of Sanskrit, largely preferring to write in Pāli and Prakrit. At a certain point, however, and for unknown reasons, Buddhist thinkers such as Nāgārjuna begin to write in Sanskrit (Kelly 1996). Regardless of which language they employ, Buddhists reject the notion of an inherent connection between the Sanskrit language and reality—indeed, they argue that no language has such a connection—arguing as early on as the famous The Questions of King Milinda (Milindapañhā) that language is conventional. Still, the fact that Naiyāyikas and Buddhists agree on the conventional nature of language shows that the religious prominence of Sanskrit does not necessarily entail specific philosophical commitments about its referential capacities. However, those who take on the assumption of an innate connection between Sanskrit word and referent then had explanatory burdens, such as how to explain linguistic innovation within Sanskrit and the referential capacities of non-Sanskrit languages.
