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)

  1. (aorist)
    1. to see, behold, perceive
      1. (strengthened) to look at, observe
      2. to see a person, to meet, speak with them
      3. to see, experience, become acquainted with
    2. to look at or towards
      1. to look, appear, seem
    3. to see mentally, to perceive
      1. to examine, investigate
  2. (present middle/passive)
    1. to be seen, appear
    2. (with infinitive) to appear, seem
    3. (in a strict middle sense, with dative) to make oneself like
      1. (intransitive) to be like

Usage notesEdit

  • The verb's active present tense is not in use and it is replaced by ὁράω (horáō).
  • οἶδα (oîda), while an apparent inflection of εἴδομαι (eídomai), functions as a present tense word with its own meaning.
