Sri Lankan Tamil dialects

The Negombo Tamil dialect, used in the Negombo area by bilingual fishers who otherwise identify themselves as Sinhalese, has undergone considerable morphosyntactic convergence with spoken or colloquial Sinhala as a consequence of contact with it.[5][6] It has also developed a number of other grammatical traits under the probable influence of Sinhala, including a postposed indefinite article, an indefinitizing postclitic –sari (apparently modeled on Sinhala –hari), and case assignments for defective verbs that follow the Sinhala, rather than Tamil, patterns of agreement.[5]

Batticaloa Tamil dialect is shared between Tamils, Moors, Veddhas and Portuguese Burghers in the eastern province. The Tamil dialect used by residents of the Trincomalee district has many similarities with the Jaffna Tamil dialect.[7] According to Kamil Zvelebil a linguist, the Batticaloa Tamil dialect is the most literary like of all spoken dialects of Tamil, and it has preserved several very antique features, and has remained more true to the literary norm than any other form of Tamil while developing a few striking innovations. Although Batticaloa Tamil has some very specific features of vocabulary, it is classified with other Sri Lankan Tamil dialects as it is related to them by characteristic traits of its phonology. It also maintains some words that are unique to present day .[3][8]

The dialect used in Jaffna is the oldest and most archaic of Tamil dialects in Sri Lanka and India. It is also very refined and considered to preserve many antique features of Old Tamil that predate Tolkāppiyam, the grammatical treatise of Tamil. The Jaffna Tamil dialect retained many forms of words which were used in Sangam literature such as Tirukkuṛaḷ and Kuṟuntokai.[9] Also a large portion of settlers in Jaffna who came from South India in the past centuries were Vellalar and this would have helped retain classical linguistic features since Vellalars speak a classic dialect of Tamil. Jaffna Tamil dialect is not mutually intelligible with Indian Tamil dialects, though both share a diglossic `H' variety in literary Tamil.[10] It is frequently mistaken for Malayalam by native Indian Tamil speakers.[11] There are a number of Prakrit loans words that are unique to the Jaffna Tamil.[12] A subdialect retained by the Paraiyar people of Kayts still retains a number of archaic words and Prakrit loans not found in any other dialects of Tamil. These drummers had historically played an important role as ritual players of drums at funerals and folk temples and as heralds and traditional weavers. They also maintained the family records of their feudal lords and even practiced medicine and astrology in folk traditions [13]
