Pronunciation

  • Classical: [ˈeː.tʰɔs][1]
  • Ecclesiastical: [ˈɛː.tos][1]

Forms

ēthos n (genitive ētheos); irregular, third declension[1]

Etymology

It is borrowed from Ancient Greek ἦθος (êthos, “custom, character”).[2][1][3] The Greek word means “custom, usage”, in the plural “haunts”;[4] it differs from ἔθος (éthos, “custom”) only by its long vowel.[4]

Earliest recorded meaning

The first record is in Varro's Menippean Satires,[2][3] in the plural: in argumentis Caecilius poscit palmam, in ethesin Terentius “in plots Caecilius claims the prize, in characters Terence”.[2] Varro lived 116–27 BC.[5]

Semantic evolution

Latin kept it as a Greek term of literary criticism and rhetoric, for the portrayal of character, often paired with pathos.[2][3] Pliny the Elder uses the plural ēthē for the depiction of character.[6] Servius says that Virgil gave the fourth book of the Aeneid to ethos,[3] and Sidonius Apollinaris uses it for ethics or morals beside physics and logic.[6][3] English took ethos directly from Greek in the 19th century.[7]

Timeline

  • 116–27 BC – Varro uses the plural of characters in comedy.[2][5]
  • 23/24–79 AD – Pliny the Elder uses it of the depiction of character.[6][5]
  • c. 400 AD – Servius assigns ethos to the fourth book of the Aeneid.[3][5]
  • c. 431–486 AD – Sidonius Apollinaris uses it of ethics.[6][3][5]
