Pronunciation

  • 5th-century BC Attic: /peː.rá.ɔː/[1]
  • 4th-century AD Koine: /piˈra.o/[1]
  • 10th-century Byzantine: /piˈra.o/[1]

Forms

πειρᾰ́ω (peiráō) [1] Ionic future πειρήσω and aorist ἐπείρησα, Laconian third person imperative πηρήτω in Alcman.[2]

Etymology

It is a denominative verb formed from Ancient Greek πεῖρα (peîra, “trial, attempt”) + -άω (-áō).[1][3] The noun is from Proto-Greek *περ-ι̯α (*per-ia), seen in Aeolic πέρρα (pérra), formed like στεῖρα (steîra) and μοῖρα (moîra).[3][4] Frisk grants that the noun could be a back-formation from the verb, but then the verb's own formation is hard to explain.[4]

Beekes derives the noun from Proto-Indo-European *per- (“to cross, pass”), the root of πείρω (peírō, “to pierce”) and περάω (peráō, “to pass through”), a link that Frisk too thinks very probable.[3][4] The only sure cognates, in Frisk's view, are Latin perītus (“experienced”), perīculum (“trial, danger”) and experior (“to try, test”), whose /iː/ seems connected with the Greek suffix; an Armenian word for “trial” belongs here only if its aspirated initial is expressive.[4][5]

Earliest recorded meaning

Homer uses both the active and the middle, of testing a person or a thing and of making an attempt on an enemy: the Iliad has “let no one try to cut short my word”.[6][7][8]

Semantic evolution

The middle πειράομαι (peiráomai) is commoner than the active from Homer on.[7] With the genitive it means to make trial of a person or a thing, or to try one's chance at a contest; with the infinitive, to try to do something (Herodotus, Aristophanes, Xenophon, Plato).[7] The active is used in the same senses, and absolutely of a military attempt: Thucydides has an attempt by sea.[7][2] Aristophanes, Lysias and Xenophon use the active for advances made to a woman, and Thucydides the passive of Harmodius, the object of Hipparchus' advances.[7][2] Lucian uses it with the accusative for “to experience”.[7]

The Septuagint uses it beside πειράζω (peirázō) for testing, of people who test God and of God testing people.[9] The New Testament has only the middle, “to try”, as in “the Jews tried to kill me” in Acts.[10] From the same family come πειρατής (peiratḗs), “pirate”, in Hellenistic Greek.[3]
