  • 4th-century AD Koine: /inˈdos/[1]
  • 10th-century Byzantine: /inˈdos/[1]

Forms

Ἰνδός (Indós) m (genitive Ἰνδοῦ); second declension[1]

Etymology

It is borrowed from Old Persian hiⁿdūš, the name of the Indus and its land in the Old Persian inscriptions,[1][2] from Proto-Iranian *hínduš, from Proto-Indo-Iranian *síndʰuš (“river”), of uncertain origin.[1] The Persian form, with Iranian /h/ for /s/, was taken over without the /h/, as in Ionic.[2]

The Indian form itself is Sanskrit सिन्धु (síndhu, “river, stream”), which reached Greek separately as Σίνθος (Sínthos), the name of the river in the Periplus of the Erythraean Sea.[1][2] From the river name the Greeks formed Ἰνδική (Indikḗ) for the country.[2]

Earliest recorded meaning

Aeschylus has the Indians in the Suppliants, and Herodotus uses the word both for the Indians and for the river.[3][4][5] According to Smith, Hecataeus of Miletus was the first to mention the river.[6]

Semantic evolution

India became known in Greece in the late 6th century BC through Scylax, who explored the Indus for Darius, and Herodotus mentions his voyage when he names the river.[2] Herodotus and Ctesias relied on Persian information, while Scylax and later Alexander the Great explored the lower course of the river.[2]

In the Hellenistic period the word was used especially of the Indian drivers of war elephants, as in Phylarchus and Polybius, and Hesychius glosses it as a man who leads an elephant, citing 1 Maccabees.[3][7] As an adjective it meant “Indian” in later epigrams, and the feminine named a medical plaster.[3] It also named a fallacy in Plutarch.[3]

The word was borrowed into Coptic, with a first record in AD 375,[8] and into Latin Indus.[1][2] Medieval vernacular Greek kept it for an inhabitant of India, and it is still used in Modern Greek as Ινδός (Indós).[9][1]
