Substratum in Vedic Sanskrit
has a number of linguistic features which are alien to most other Indo-European languages. Prominent examples include: phonologically, the introduction of retroflexes, which alternate with dentals, and morphologically, the formation of gerunds; Some philologists attribute such features, as well as the presence of non-Indo-European vocabulary, to a local substratum of languages encountered by Indo-Aryan peoples in Central Asia and within the Indian subcontinent, including the Dravidian languages.
Scholars have identified a substantial body of loanwords in the earliest Indian texts, including clear evidence of Non-Indo-Aryan elements. While some loanwords are from Dravidian, and other forms are traceable to Munda or Proto-Burushaski, the bulk have no sensible basis in any of these families, suggesting a source in one or more lost languages. The discovery that some loan words from one of these lost sources had also been preserved in the earliest Iranian texts, and also in Tocharian, convinced Michael Witzel and Alexander Lubotsky that the source lay in Central Asia and could be associated with the Bactria–Margiana Archaeological Complex. Another lost language is that of the Indus Valley Civilization, which Witzel initially labelled Para-Munda, but later the Kubhā-Vipāś substrate.
Phonology
Retroflex phonemes are now found throughout the Burushaski, Nuristani, Dravidian and Munda families. They are reconstructed for Proto-Burushaski, Proto-Dravidian and for Proto-Munda, and are thus clearly an areal feature of the Indian subcontinent. They are not reconstructible for either Proto-Indo-European or Proto-Indo-Iranian, and they are also not found in Mitanni–Indo-Aryan loanwords.The acquisition of the phonological trait by early Indo-Aryan is thus unsurprising, but it does not immediately permit identification of the donor language. Since the adoption of a retroflex series does not affect poetic meter, it is impossible to say if it predates the early portions of the Rigveda or was a part of Indo-Aryan when the Rigvedic verses were being composed; however, it is certain that at the time of the redaction of the Rigveda, the retroflex series had become part of Sanskrit phonology. There is a clear predominance of retroflexion in the Northwest, involving affricates, sibilants and even vowels, compared to other parts of the subcontinent. It has been suggested that this points to the regional, northwestern origin of the phenomenon in Rigvedic Sanskrit. Bertil Tikkanen is open to the idea that various syntactical developments in Indo-Aryan could have been the result of adstratum rather than the result of substrate influences. However Tikkanen states that "in view of the strictly areal implications of retroflexion and the occurrence of retroflexes in many early loanwords, it is hardly likely that Indo-Aryan retroflexion arose in a region that did not have a substratum with retroflexes."
Not only the typological development of Old to Middle Indo-Aryan, but already the phonological development from Pre-Vedic to Vedic is suggestive of Dravidian influence.
Vocabulary
In 1955 Burrow listed some 500 words in Sanskrit that he considered to be loans from non-Indo-European languages. He noted that in the earliest form of the language such words are comparatively few, but they progressively become more numerous. Though mentioning the likelihood that one source was lost Indian languages extinguished by the advance of Indo-Aryan, he concentrated on finding loans from Dravidian. Kuiper identified 383 specifically Rigvedic words as non-Indo-Aryan – roughly 4% of its vocabulary. Oberlies prefers to consider 344–358 "secure" non-Indo-European words in the Rigveda. Even if all local non-Indo-Aryan names of persons and places are subtracted from Kuiper's list, that still leaves some 211–250 "foreign" words, around 2% of the total vocabulary of the Rigveda.These loanwords cover local flora and fauna, agriculture and artisanship, terms of toilette, clothing and household. Dancing and music are particularly prominent, and there are some items of religion and beliefs. They only reflect village life, and not the intricate civilization of the Indus cities, befitting a post-Harappan time frame. In particular, Indo-Aryan words for plants stem in large part from other language families, especially from the now-lost substrate languages.
Mayrhofer identified a "prefixing" language as the source of many non-Indo-European words in the Rigveda, based on recurring prefixes like ka- or ki-, that have been compared by Michael Witzel to the Munda prefix k- for designation of persons, and the plural prefix ki seen in Khasi, though he notes that in Vedic, k- also applies to items merely connected with humans and animals. Examples include:
- काकम्बीर kākambīra a certain tree
- ककर्दु kakardu "wooden stick"
- कपर्दिन् kapardin "with a hair-knot"
- कर्पास karpāsa "cotton"
- कवन्ध kavandha "barrel"
- कवष kavaṣa "straddle-legged"
- किलास kilāsa "spotted, leprous"
- किमीद kimīda "a demon", cf. शिमिदा śimidā "a demoness"
- कीनाश kīnāśa "ploughman"
- कियम्बु kiyāmbu a water plant
- कुलाय kulāya "nest"
- कुलिश kuliśa "axe"
- कुमार kumāra "boy"
- कुलुङ्ग kuluṅga "antelope"
- कुरुङ्ग Kuruṅga name of a chieftain of the Turvaśa.
The Indo-Europeanist and Indologist Thieme has questioned Dravidian etymologies proposed for Vedic words, for most of which he gives Indo-Aryan or Sanskrit etymologies, and has condemned what he characterizes as a misplaced "zeal for hunting up Dravidian loans in Sanskrit". Das even contended that there is "not a single case" in which a communis opinio has been found confirming the foreign origin of a Rigvedic word". Kuiper answered that charge. Burrow in turn has criticized the "resort to tortuous reconstructions in order to find, by hook or by crook, Indo-European explanations for Sanskrit words". Kuiper reasons that given the abundance of Indo-European comparative material – and the scarcity of Dravidian or Munda – the inability to clearly confirm whether the etymology of a Vedic word is Indo-European implies that it is not.
Lost donor languages
could not find etymologies from Indo-European or Dravidian or Munda or as loans from Persian for 31 percent of agricultural and flora terms of Hindi. He proposed an origin in an unknown language "X". Southworth also notes that the flora terms did not come from either Dravidian or Munda. Southworth found only five terms which are shared with Munda, leading to his suggestion that "the presence of other ethnic groups, speaking other languages, must be assumed for the period in question".Language of the Bactria–Margiana Archaeological Complex (BMAC)
Terms borrowed from an otherwise unknown language include those relating to cereal-growing and breadmaking, waterworks, architecture, tools or weapons, textiles and garments and plants. Lubotsky pointed out that the phonological and morphological similarity of 55 loanwords in Iranian and in Sanskrit indicate that both share a common substratum, or perhaps two dialects of the same substratum. He concludes that the BMAC language of the population of the towns of Central Asia and the language spoken in Punjab were intimately related. However, the prevailing interpretation is that Harappan is not related, and the 55 loanwords entered Proto-Indo-Iranian during its development in the Sintashta culture in distant contact with the Bactria–Margiana Archaeological Complex, and then many more words with the same origin enriched Old Indic as it developed among pastoralists who integrated with and perhaps ruled over the declining BMAC.Examples:

Living donor languages
A concern raised in the identification of the substrate is that there is a large time gap between the comparative materials, which can be seen as a serious methodological drawback. One issue is the early geographical distribution of the South Asian languages. It should not be assumed that the present-day northern location of Brahui, Kurukh, and Malto reflects the position of their ancestor languages at the time of Indo-Aryan development. Another problem is that modern literary languages may present a misleading picture of their prehistoric ancestors. The first completely intelligible, datable, and sufficiently long and complete epigraphs that might be of some use in linguistic comparison are the Tamil inscriptions of the Pallava dynasty of about 550, and the early Tamil Brahmi inscriptions starting in the 2nd century BC. Similarly there is much less material available for comparative Munda and the interval in their case is at least three millennia. However reconstructions of Proto-Dravidian and Proto-Munda now help in distinguishing the traits of these languages from those of Indo-European in the evaluation of substrate and loan words.Dravidian
There are an estimated thirty to forty Dravidian loanwords in Vedic. Those for which Dravidian etymologies are proposed by Zvelebil include कुलाय kulāya "nest", कुल्फ kulpha "ankle", दण्ड "stick", कूल kūla "slope", बिल bila "hollow", खल khala "threshing floor". However Witzel finds Dravidian loans only from the middle Rigvedic period, suggesting that linguistic contact between Indo-Aryan and Dravidian speakers only occurred as the Indo-Aryans expanded well into and beyond the Punjab.While Dravidian languages are primarily confined to the South of India today, there is a striking exception: Brahui. It has been taken by some as the linguistic equivalent of a relict population, perhaps indicating that Dravidian languages were formerly much more widespread and were supplanted by the incoming Indo-Aryan languages. Certainly some Dravidian place-names are found in now Indo-Aryan regions of central India, and possibly even as far northwest as Sindh. However, it is now argued by Elfenbein that the Brahui could only have migrated to Balochistan from central India after 1000, because of the lack of any older Iranian loanwords in Brahui. The main Iranian contributor to Brahui vocabulary, Balochi, is a western Iranian language like Kurdish, and moved to the area from the west only around 1000.
As noted above, retroflex phonemes in early Indo-Aryan cannot identify the donor language as specifically Dravidian. Krishnamurti argues the Dravidian case for other features: "Besides, the Veda has used the gerund, not found in Avestan, with the same grammatical function as in Dravidian, as a nonfinite verb for 'incomplete' action. Vedic language also attests the use of iti as a quotative clause complementizer." However, such features are also found in the indigenous Burushaski language of the Pamirs and cannot be attributed only to Dravidian influence on the early Rigveda. A quotative uiti is also seen in Avestan.
