Etymology
It is borrowed from Ancient Greek Ἰνδός (Indós), the name of the river Indus and of the Indians.[1][3][4] Greek took the name, through Old Persian, from Proto-Indo-Iranian *síndʰuš, the word that is सिन्धु (síndhu, “river”) in Sanskrit.[1][4]
Earliest recorded meaning
Köbler dates the word to Catullus,[4] who calls ivory dēns Indus, “Indian tooth”.[3]
Semantic evolution
As a noun it named an inhabitant of India, an Indian, and the plural Indī the people;[2][3] it could also mean an elephant driver.[2] As the name of a river it meant the Indus, which flows into the Indian Ocean, and also a river of Caria.[3] As an adjective, “Indian”, it is almost exclusively poetic according to Lewis & Short,[3] and was used of ivory, of elephants and of pearls; in poetry it could mean simply “of Indian ivory”.[2][3]
