κόττος

Ancient Greek

Of unclear origin:

Beekes derives the word from κοττῐ́ς (kottĭ́s, “hairdress with long hair on the forehead”), as the crests of chickens resemble such hairstyles.^[1]
Masica considers the word as a Dravidian borrowing, and suggests either Old Tamil 𑀓𑁄𑀵𑀺 (kōḻi) or Old Telugu కోడి (kōḍi) as the source.^[2] As chickens were first domesticated in Southeast Asia and potentially passed through South Asia before arriving in Western Eurasia, this is plausible; however, the word for "chicken" in other Mediterranean languages used for sea trade (including presumably Phoenician and Etruscan) does not resemble that of the Greek or Dravidian forms, casting doubt on the theory.
