Forms
ὁ (ho) (feminine ἡ, neuter τό)[1]
Etymology
It is inherited from Proto-Hellenic *hó, inherited from Proto-Indo-European *só (“this one”), an old demonstrative whose masculine and feminine nominative began with s- and whose other forms began with t- (neuter τό (tó), from *tód).[2][1][3] The nominative plurals οἱ (hoi), αἱ (hai) of epic and Attic are analogical for the older τοί (toí), ταί (taí) of epic and Doric.[2]
Cognate with Sanskrit स (sá), feminine सा (sā́), Gothic 𐍃𐌰 (sa), Tocharian B se, Old English sē and Old Church Slavonic тъ (tŭ), and the Old Latin form sapsa (“herself”).[2][1] The relative ὅς (hós) has a different origin.[3][4]
Earliest recorded meaning
In Homer it is mostly a demonstrative and personal pronoun, “that, he, she, it”, the oldest and, there, the commonest use; it already appears as an article as well.[3][5][4]
Semantic evolution
As a demonstrative it lived on in Herodotus, in the lyric parts of tragedy and in set phrases of Attic prose, such as ὁ μέν … ὁ δέ “the one … the other”.[3][4] In Attic it became the definite article, placed before the noun, used to mark a known or representative person or thing and to make a noun of an adjective, a participle or an infinitive.[3][4] In epic and Ionic the same forms also served as a relative pronoun.[3][4]
The New Testament uses it as the definite article.[6] Medieval vernacular Greek kept the article, and Modern Greek ο (o), η, το continues it.[7][8][9]
Timeline
- Homer – The Iliad and the Odyssey use it mainly as a pronoun, “he, she, it”.[3][5]
- 5th century BC – Herodotus still often uses it as a demonstrative.[3]
- 5th–4th century BC – Attic prose uses it as the definite article, keeping the demonstrative in set phrases.[3][4]
- 1st century AD – The New Testament uses it as the article.[6]
- Modern Greek – ο (o) is still the definite article.[8]

Usage notes
The nominatives ὁ, ἡ, οἱ, αἱ are written without an accent except when used as relatives, and Herodian says they were oxytone, Apollonius Dyscolus that they were not enclitic.[3] Dialect forms include Doric ἁ (ha) for ἡ and epic τοῖο (toîo) for the genitive τοῦ.[2][4]
