The Indigenous Veddhas are ethnically related to people in South India and early populations of Southeast Asia.
It is not possible to ascertain what languages that they originally spoke as Vedda language is considered diverged from its original source.

According to K. Indrapala, cultural diffusion, rather than migration of people, spread the Prakrit and Tamil languages from peninsular India into an existing mesolithic population, centuries before the common era.
Tamil Brahmi and Tamil-Prakrit scripts were used to write the Tamil language during this period on the island.

Settlements of culturally similar early populations of ancient Sri Lanka and ancient Tamil Nadu in India were excavated at megalithic burial sites at Pomparippu on the west coast and in Kathiraveli on the east coast of the island.
Bearing a remarkable resemblance to burials in the Early Pandyan Kingdom, these sites were established between the 5th century BCE and 2nd century CE.
Excavated ceramic sequences similar to that of Arikamedu were found in Kandarodai (Kadiramalai) on the north coast, dated to 1300 BCE.
Cultural similarities in burial practices in South India and Sri Lanka were dated by archaeologists to 10th century BCE.
However, Indian history and archaeology have pushed the date back to 15th century BCE.
In Sri Lanka, there is radiometric evidence from Anuradhapura that the non-Brahmi symbol-bearing black and red ware occur in the 10th century BCE.
The skeletal remains of an Early Iron Age chief were excavated in Anaikoddai, Jaffna District.
The name Ko Veta is engraved in Brahmi script on a seal buried with the skeleton and is assigned by the excavators to the 3rd century BCE.
Ko, meaning "King" in Tamil, is comparable to such names as Ko Atan, Ko Putivira and Ko Ra-pumaan occurring in contemporary Tamil Brahmi inscriptions of ancient South India and Egypt.
