Etymology

Speakers of Telugu refer to it as simply Telugu or Telugoo. Older forms of the name include Teluṅgu and Tenuṅgu. Tenugu is derived from the Proto-Dravidian word *ten ("south") to mean "the people who lived in the south/southern direction" (relative to Sanskrit and Prakrit -speaking peoples). The name Telugu, then, is a result of an "n" to "l" alternation established in Telugu.

The popular belief holds that Telugu is derived from Trilinga of Trilinga Kshetras being the land bounded by the three Lingas which is Telugu homeland. P. Chenchiah and Bhujanga Rao note that Atharvana Acharya in the 13th century wrote a grammar of Telugu, calling it the Trilinga Śabdānusāsana (or Trilinga Grammar). However, most scholars note that Atharvana's grammar was titled Atharvana Karikavali. Appa Kavi in the 17th century explicitly wrote that Telugu was derived from Trilinga. Scholar C. P. Brown made a comment that it was a "strange notion" since the predecessors of Appa Kavi had no knowledge of such a derivation.

George Abraham Grierson and other linguists doubt this derivation, holding rather that Telugu was the older term and Trilinga must be the later Sanskritisation of it. If so the derivation itself must have been quite ancient because Triglyphum, Trilingum and Modogalingam are attested in ancient Greek sources, the last of which can be interpreted as a Telugu rendition of " Trilinga ".
