Indo-Aryan loanwords in Tamil

The Tamil language of Dravidian family has absorbed many loanwords from Indo-Aryan family, predominantly from Prakrit, Pali and Sanskrit, ever since the early 1st millennium CE, when the Sangam period Chola kingdoms became influenced by spread of Jainism, Buddhism and early Hinduism. Many of these loans are obscured by adaptions to Tamil phonology.

There are many words that are cognates in Sanskrit and Tamil, in both tatsama and tadbhava forms. This is an illustrative list of Tamil words of Indo-Aryan origin, classified based on type of borrowing. The words are transliterated according to IAST system. All words have been referenced with the Madras University Tamil Lexicon, which is used as the most authoritative and standard lexicon by mainstream scholars.
