Pronunciation

  • 5th-century BC Attic: /au̯.tós/[1]
  • 4th-century AD Koine: /aɸˈtos/[1]
  • 10th-century Byzantine: /afˈtos/[1]

Forms

αὐτός (autós) (feminine αὐτή, neuter αὐτό)[1] Cretan ἀϝτός, and Attic contracts ὁ αὐτός to αὑτός, neuter ταὐτό or ταὐτόν.[2][3]

Etymology

It is inherited from Proto-Hellenic *autós (“self”).[1] Its further origin is uncertain: Beekes derives it from Proto-Indo-European *h₂ew (“again”) and the pronominal stem *to- (“that”), and Risch from Greek αὖ (aû, “again”) and τόν (tón).[4][1] The DGE likewise explains it as two pronominal and adverbial elements, αὖ (aû) and the ⟨-το-⟩ of other pronouns, run together.[5] Frisk points out that the grammatical sense “self” must have grown out of an older concrete use that is unknown, so that every etymology has limited value; he and Beekes mention a comparison with Gothic 𐌰𐌿𐌸𐍃 (auþs, “desolate”).[6][4] Wiktionary lists Phrygian αυτος (autos) as an exact cognate.[1]

Earliest recorded meaning

It is found from Homer on: the first lines of the Iliad already use it for the heroes' bodies, as against their souls.[7][2]

Semantic evolution

Its first sense was emphatic, “self”, setting a person or thing off from others: one's true self, the king as against his subjects, someone acting of his own accord or alone.[2][3] In its oblique cases it served as the pronoun of the third person, “him, her, it”, while with the article it meant “the same”.[2][3][4] Plato used it of an abstract idea taken in itself, such as justice itself.[2]

In later Greek it was used for “he” in the nominative too, as in Luke's Gospel, and the papyri use it with the article for “the said, the above-named”.[2] The New Testament still uses it mainly as an intensive “self”.[8]

In the Middle Ages it became a plain demonstrative, and its unstressed forms were worn down (είδα αυτόν > είδα τον), which gave the clitic pronouns of Modern Greek.[9] Modern Greek αυτός (aftós) now means both “he” and “this”.[9]

Timeline

  • Homer – The Iliad uses it for “self” and, in its oblique cases, for “him, her, it”.[7][2]
  • 5th century BC – Thucydides uses it with ordinal numbers: “fifth himself” means with four others.[2][5]
  • 5th–4th century BC – Plato uses it of an idea in itself.[2][5]
  • 3rd century BC – Papyri use it with the article for “the above-named”.[2]
  • 1st century AD – Luke's Gospel uses its nominative for plain “he”.[2]
  • Modern Greek – αυτός (aftós) is both the personal pronoun “he” and a demonstrative.[9]
