Ancient Greek[edit]

Etymology[edit]

From Proto-Indo-European *wóyd-. Compare the very closely related εἴδομαι (eídomai, to see). Cognates include Old Armenian գիտեմ (gitem), Sanskrit वेद (veda), Latin vīdī, and Proto-Germanic *witaną (English wit).

Pronunciation[edit]

 

Verb[edit]

οἶδᾰ (oîda)

  1. to know
    1. (with infinitive)
    2. (with participle) to know that
    3. (the fact is often added as a separate clause)
    4. (οὐκ οἶδα εἰ) I don't know, indicating disbelief or doubt
    5. (similar ellipses are frequent with other conjunctions)
    6. (parenthetic)
    7. (a superlative is often followed by the phrase "ὧν ἴσμεν")

Usage notes[edit]

The perfect inflections function as present tense, and the pluperfect as imperfect.

Inflection[edit]

The inflection is highly variable and irregular, yet reflects a more archaic inflectional pattern.
