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.

Present: εἴδομαι
