Tirunelveli Tamil also known as Nellai Tamil or ThenPaandi Tamil is one of the dialects of Tamil which is spoken in the districts of Tirunelveli, Tenkasi, Thoothukudi,Kanyakumari and some parts of Virudhunagar as well as over the vast area of south Tamil Nadu which was once ruled by the Pandiya Kings.
Thenpaandi Seemai refers to the part of a Pandya kingdom which includes the present day Kanyakumari,Tirunelveli, Tenkasi and Tuticorin, some parts of Ramanathapuram, Virudunagar Districts.It differs substantially from Madurai Tamil[1][2] The Tirunelveli Tamil Dialect (TTD) has on the whole 41 phonemes of which 31 are segmental and the remaining 10 are suprasegmental.
[3] Nellai Tamil also preserves archaic kinship terms that other dialects have long discarded.
However, the most unusual feature of the Tamil spoken in the Tirunelveli region is that the medial "c" is pronounced as a voiceless palatal affricate as in Old Tamil and has not undergone the change to the dental "s" as in most other dialects.
