Ancient GreekEdit


From Proto-Indo-European *weyd- (to know; see), compare the very closely related οἶδα (oîda). Cognate with Latin videō, Sanskrit वेत्ति (vetti), Old Armenian գիտեմ (gitem), Old Church Slavonic вѣдѣти (věděti), and Old English witan (English wit).




εἴδομαι (eídomai) (poetic)

  1. to be seen, appear
  2. (with infinitive) to appear, seem to do
  3. (reflexive, with dative) to make oneself like
    1. (intransitive) to be like, to look like

Usage notesEdit

  • The aorist tense, εἶδον (eîdon, I saw), has a related but different meaning, and its second aorist middle form, εἰδόμην (eidómēn), contrasts with the first aorist middle of this verb, εἰσᾰ́μην (eisámēn).
  • The perfect tense, οἶδα (oîda, I know), functions as a present tense word with its own meaning.
