Forms
ἑταῖρος (hetaîros) m (genitive ἑταίρου); second declension[1] Epic ἕταρος (hétaros), Aeolic ἔταιρος (étairos); feminine ἑταίρα (hetaírā) and ἑτάρη (hetárē).[2][3]
Etymology
It is remodelled from Ancient Greek ἕταρος (hétaros, “companion”), the older epic form.[4][3] From ἕταρος a feminine was first made with the suffix ⟨‑ια⟩ (as χίμαιρα (khímaira) beside χίμαρος (khímaros)), which became ἑταίρα (hetaírā), and the masculine ἑταῖρος was then formed beside it.[4][3]
Since ἕταρος shows no trace of a digamma, it cannot come directly from ἔτης (étēs) “kinsman”, which had one.[4][3] Beekes and Frisk start instead from the reflexive Proto-Indo-European *se with a /t/ extension, as in Lithuanian svẽčias (“guest”), and the suffix ⟨‑ρος⟩ of νεαρός (nearós).[4][3][1] De Lamberterie connects it with ἐτεός (eteós) “true” and ὅσιος (hósios).[4]
Ancient writers derived it from ἔθος (éthos) “custom” or from ἕτερος (héteros) “other”: Plutarch says a friend is called a “companion” as being another self.[5]
Earliest recorded meaning
In Homer it is a comrade, a companion in war, such as the followers of a chief and the crew of Odysseus.[6][2]
Semantic evolution
From the comrade in arms it widened to any companion or friend.[2] Xenophon calls Socrates' pupils his companions, and Aristotle uses it of a philosopher's followers.[2][7] In Thucydides, Lysias and Demosthenes the plural names members of a political club,[2] while Semonides and Aristophanes use it of a woman's lover, and in Macedonia the Companions were the king's elite cavalry.[2] In the New Testament it is a friendly but distant address, as in the Gospel of Matthew.[7]
Modern Greek εταίρος (etaíros) is a learned word for a member of an academy, a company or an alliance; these uses follow French associé and partenaire and English partner.[8][9] It still names the Companions of the Macedonian king.[8]
