  • 4th-century AD Koine: /ˈi.ðon/[1]
  • 10th-century Byzantine: /ˈi.ðon/[1]

Forms

εἶδον (eîdon) [1] Second aorist, used as the aorist of ὁράω (horáō): infinitive ἰδεῖν (ideîn), participle ἰδών (idṓn), subjunctive ἴδω (ídō), imperative ἴδε (íde), Attic ἰδέ (idé); Epic unaugmented ἴδον (ídon), iterative ἴδεσκον (ídeskon); middle εἰδόμην (eidómēn), Epic ἰδόμην (idómēn), mostly in verse.[2][3] Koine also has mixed forms with first-aorist endings, such as εἶδα (eîda) and εἴδαμεν (eídamen), and the spelling ἴδον (ídon), often as variants in the New Testament manuscripts.[3]

Etymology

It is inherited from Proto-Indo-European *h₁é-wid-et,[4] an old thematic root aorist of Proto-Indo-European *weyd- (“to see, catch sight of”).[4][5][1] The augment ⟨ἐ-⟩ contracted with the following syllable after the loss of the digamma: ἔϝιδον (éwidon) became εἶδον.[6][7] Formally it is identical with Old Armenian եգիտ (egit, “he found”) and Sanskrit अविदत् (ávidat, “he found”).[4][5] Latin videō (“to see”) is a cognate.[4][7]

The root had no present of this kind in Greek: the present was supplied by ὁράω (horáō), and the perfect of the same root, οἶδα (oîda), means “I know”.[4][7][2] The middle present εἴδομαι (eídomai, “to appear, seem”) and the noun εἶδος (eîdos, “appearance, form”) belong to the same root.[4]

Earliest recorded meaning

It is found from Homer on, meaning to see or behold something with the eyes, to look at it, or to examine it.[2][7] Homer already has the infinitive after a noun, as in θαῦμα ἰδέσθαι “a marvel to behold”.[7]

Semantic evolution

From seeing with the eyes the verb moved to experiencing (to “see” one's homecoming or one's slavery) and to meeting someone; in Aeschylus it also means to have an eye to gain.[2] The imperative ἴδε, Attic ἰδέ, became an exclamation, “look!”, even when said to several people (Sophocles, Euripides, Theocritus, the New Testament); the middle imperative gave the interjection ἰδού (idoú).[2]

In Koine the aorist took the endings of the first aorist, as in εἶδα, and such forms are frequent among the manuscript readings of the New Testament.[3] Medieval Greek kept είδα (eída), refashioned after the other aorists in -α such as έγραψα (égrapsa).[8] In Modern Greek είδα (eída) is the aorist of βλέπω (vlépo, “to see”), with the imperative δες (des).[8][1]

Timeline

  • Homer – The Iliad uses it for seeing, looking at and examining.[2][7]
  • 6th–5th century BC – Aeschylus uses it for having an eye to gain.[2][9]
  • 5th century BC – Sophocles and Euripides use the imperative as an exclamation, “look!”.[2][9]
  • 1st century AD – The New Testament manuscripts often have mixed forms such as εἶδα and εἴδαμεν.[3]
  • Medieval Greek – It becomes είδα (eída), with the ending of the aorists in -α.[8]
  • Modern Greek – είδα (eída) serves as the aorist of βλέπω (vlépo).[8]
