The earliest known use of the word "Saṃskṛta" (Sanskrit), in the context of a speech or language, is found in verses 5.28.17–19 of the "Ramayana". Outside the learned sphere of written Classical Sanskrit, vernacular colloquial dialects (Prakrits) continued to evolve. Sanskrit co-existed with numerous other Prakrit languages of ancient India. The Prakrit languages of India also have ancient roots and some Sanskrit scholars have called these "Apabhramsa", literally "spoiled". The Vedic literature includes words whose phonetic equivalent are not found in other Indo-European languages but which are found in the regional Prakrit languages, which makes it likely that the interaction, the sharing of words and ideas began early in the Indian history. As the Indian thought diversified and challenged earlier beliefs of Hinduism, particularly in the form of Buddhism and Jainism, the Prakrit languages such as Pali in Theravada Buddhism and Ardhamagadhi in Jainism competed with Sanskrit in the ancient times. However, states Paul Dundas, a scholar of Jainism, these ancient Prakrit languages had "roughly the same relationship to Sanskrit as medieval Italian does to Latin." The Indian tradition states that the Buddha and the Mahavira preferred the Prakrit language so that everyone could understand it. However, scholars such as Dundas have questioned this hypothesis. They state that there is no evidence for this and whatever evidence is available suggests that by the start of the common era, hardly anybody other than learned monks had the capacity to understand the old Prakrit languages such as Ardhamagadhi.
