Etymology

Wiktionary and Beekes's Pre-Greek lexicon consider it and πέτρα (pétra, “rock”) Pre-Greek, noting the suffix -ρ-.[1][2] Wackernagel took the feminine to be an old collective beside πέτρος, as Chantraine and Frisk accept.[3][4] Frisk calls the pair unexplained, and Chantraine finds none of the proposed etymologies satisfactory: a link with πίπτω (píptō, “to fall”), with Latin impetīgō, with taberna through metathesis, or with πετάννυμι (petánnumi, “to spread out”).[4][3][5]

Earliest recorded meaning

In Homer it is a stone that warriors pick up and throw in battle; the word is found only in the Iliad, never in the Odyssey.[6][7]

Semantic evolution

Pindar and the tragedians use it of stones thrown or used for stoning, and also of stone objects: a discus, a grave column, a person turned to stone.[8][6] In Sophocles and Euripides it is the image of a hard heart or of insensibility.[8][9] Euripides and Plato have the proverb “to move every stone”, meaning to leave nothing untried.[6][8] It remained a poetic word; the usual prose word for a stone is λίθος (líthos).[6][4] Later poets sometimes make it feminine, under the influence of λίθος.[6][3]

The name Πέτρος (Pétros), given to the apostle Simon, is the Greek counterpart of the Aramaic name Κηφᾶς (Kēphâs),[10] and Chantraine derives it from πέτρα.[3] BDAG notes that it can hardly be shown as a name before Christianity.[10]

Timeline

  • Homer – The Iliad uses it of stones thrown by warriors.[7][6]
  • 6th–5th century BC – Pindar uses it of a thrown stone and of a grave column, and Aeschylus of stones thrown in battle.[6][8][11]
  • 5th century BC – Sophocles uses it of stoning and as an image of insensibility, and Euripides has the proverb “to move every stone”.[6][8][11]
  • 5th–4th century BC – Xenophon uses it of stones rolled down on attackers.[6][11]
  • 1st century AD – The Gospels give the name Peter to the apostle Simon, as the counterpart of Aramaic Kephas.[10][3]

Meanings

Noun

  1. A stone, a detached piece of rock or a boulder, especially one thrown as a missile or used in stoning.[6][8]
  2. An object made of stone: a discus, a grave column, a petrified person.[8]
  3. (figurative) An image of hard-heartedness or insensibility.[8][6]
  4. (proverb) πάντα κινῆσαι πέτρον, “to move every stone”: to leave nothing untried.[6][8]
  5. A kind of reed.[6]

Usage notes

LSJ distinguishes it from πέτρα (pétra), a rock or cliff, and Chantraine explains πέτρα as the collective beside it; in late Greek πέτρα itself came to mean a stone.[6][3][4]
