Pronunciation

  • 5th-century BC Attic: /ho.mûː/[1]
  • 4th-century AD Koine: /oˈmu/[1]
  • 10th-century Byzantine: /oˈmu/[1]

Forms

ὁμοῦ (homoû) [1] Aeolic ὔμοι (úmoi), in Sappho.[2][3]

Etymology

It is from Ancient Greek ὁμός (homós, “one and the same, common”), whose genitive singular came to be used as an adverb.[1][4][5] Babiniotis instead analyses it as the stem with an adverbial ending ⟨-οῦ⟩, as in πολλαχοῦ (pollakhoû) and ἀλλαχοῦ (allakhoû).[6]

The adjective is the old Indo-European word for “one and the same”, from Proto-Indo-European *somh₂ós (“same, alike”).[4][1] Cognate with Sanskrit सम (sama), Old Persian hama, Old Church Slavonic самъ (samŭ) and Old English sama, the source of English “same”.[1][4] Within Greek it belongs with εἷς (heîs, “one”) and ἅμα (háma, “at once”).[4][1]

Earliest recorded meaning

It is found from the Iliad on, meaning “in the same place” or “at the same time”: the opening book fears that war and plague together will destroy the Achaeans.[5][3][7]

Semantic evolution

In Homer it means both “in one place” and “at one time”, and with the dative “together with”, of going with the clouds or lying among the dead.[5][2][3] It is often added to two nouns already joined by “and”, like English “both”.[2][3] In tragedy and comedy it can mean “close at hand”, and the orators use it with numbers, “in all, altogether”; with τι it means “nearly, approximately”.[2][3]

The Koine kept the word: in the New Testament the disciples are “together” in one place, and two run together.[8] It passed into Medieval Greek as a learned word,[9] and Modern Greek uses ομού (omoú), “together”, only in formal style.[10]

Timeline

  • Homer – The Iliad uses it for “in the same place”, “at the same time”, and with the dative “together with”.[5][2]
  • 7th–6th century BC – Sappho has the Aeolic form ὔμοι (úmoi).[2][11]
  • 5th century BC – Sophocles uses it for “close at hand”.[2][3]
  • 4th century BC – Demosthenes uses it with numbers, “in all”.[2][3]
  • 1st century AD – The New Testament uses it of people gathered or running together.[8]
  • Modern Greek – ομού (omoú) survives as a learned word for “together”.[10]

  • ὁμόσε (homóse)
  • ὁμόθεν (homóthen)
  • ὅμως (hómōs)
  • ἅμα (háma)
  • εἷς (heîs)

Usage notes

The synonym lexicon of Ammonius distinguishes it from ἅμα (háma): ἅμα refers to time, ὁμοῦ to place, so that Solon and Anacharsis, who flourished in the same period, lived ἅμα but not ὁμοῦ.[12]
