எட்டிமொலோகி ஒப் தமிழ்

The exact period when the name "Tamil" came to be applied to the language is unclear, as is the precise etymology of the name. The earliest attested use of the name is in a text that is perhaps as early as the 1st century BCE.

Southworth suggests that the name comes from tam-miḻ > tam-iḻ 'self-speak', or 'one's own speech'. Kamil Zvelebil suggests an etymology of tam-iḻ, with tam meaning "self" or "one's self", and "-iḻ" having the connotation of "unfolding sound". Alternately, he suggests a derivation of tamiḻ < tam-iḻ < *tav-iḻ < *tak-iḻ, meaning in origin "the proper process (of speaking)"
