Forms

ποῖ (poî) [1]

Etymology

It is a locative form inherited from Proto-Indo-European *kʷos (“who, which”), the interrogative stem πο- with the locative ending -ι.[2][1] The same stem gives ποῦ (poû, “where”), πόθεν (póthen, “from where”) and ποῖος (poîos).[2] Ionic has κο- in these words.[2] Cognate with Latin quod (“what”).[2]

Earliest recorded meaning

It is first found in Aeschylus, as an interrogative meaning “whither?”, to what place.[3][4][5]

Semantic evolution

It is common in tragedy, comedy and Attic prose.[4] With a genitive it asks “to what point of”: ποῖ γῆς “to what place on earth?”, and ποῖ φρενῶν “to what point of thought?”.[4] It could also ask “to what end?” and, in Aristophanes, “how long?”.[4]

The grammarians distinguished it from ποῦ: ποῖ and πῇ ask where to, ποῦ where at, so “ποῦ ἀπέρχῃ;” for “where are you going?” was counted a mistake.[6]

Timeline

  • 6th–5th century BC – Aeschylus uses it in questions such as “to what land?”.[3][4][5]
  • 5th century BC – Sophocles uses it with a genitive of thought.[4][5]
  • 5th–4th century BC – Aristophanes uses it for “how long?”.[4][5]
  • 1st–2nd century AD – The First Epistle of Clement uses it.[7]

Usage notes

Ammonius distinguishes ποῖ and πῇ, “to where”, from ποῦ, “where”, and the Doric adverbs of place in the same way.[6] The unaccented enclitic ποι means “somewhere, to some place”.[4][2]
