To see (κατανοέω katanoeō)

And how can you see the splinter in your brother’s eye, and not see the board in your own eye? (Mt 7:3)

τί δὲ βλέπεις τὸ κάρφος τὸ ἐν τῷ ὀφθαλμῷ τοῦ ἀδελφοῦ σου, τὴν δὲ ἐν τῷ σῷ ὀφθαλμῷ δοκὸν οὐ κατανοεῖς;

Quid autem vides festucam in oculo fratris tui: et trabem in oculo tuo non vides?
