The word “overconfident” does bear similarities with the word “hyperiphanos.”
More specifically their exact meanings are as follows:
“Overconfident”: Excessively or unreasonably confident.
“Hyperiphanos” (ὑπερήφανος in Greek), a compound adjective from ὑπέρ (hyper) and phaínō, "shine forth") means
“showing oneself above others” and therefore, depending on the context, it can also mean “proud, arrogant, disdainful.”

You are welcome, Cody! I would say it is a matter of context. Would you like me to have a look at the specific passage(s)?11/14/21

Actually that would be perfect. Romans 1:30 and Mark 7:22 are two really good examples of what I am talking about. Are those texts saying that it is a sin to be overconfident or a sin to be arrogant? In that context it seems like a huge difference between the two. Thanks!!11/14/21

Definitely both passages consider pride/arrogance as a sin, but furthermore the first passage (1:30) brings both adjectives “proud” and “boastful” next to each other as sins: ΠΡΟΣ ΡΩΜΑΙΟΥΣ 1:30 TGV 1.30 ψιθυριστάς, καταλάλους, θεοστυγεῖς, ὑβριστάς, ὑπερηφάνους, ἀλαζόνας, ἐφευρετὰς κακῶν, γονεῦσιν ἀπειθεῖς, [They are] slanderers, backstabbers, God-haters, insulters, proud, boastful, inventors of evil deeds, disobedient to their parents." (My translation) ----- ΚΑΤΑ ΜΑΡΚΟΝ 7:22 κλοπαί, πλεονεξίαι, πονηρίαι, δόλος, ἀσέλγεια, ὀφθαλμὸς πονηρός, βλασφημία, ὑπερηφανία, ἀφροσύνη· [from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders,] thefts, greed, wickedness, deceit, lewdness, an evil eye, blasphemy, pride, foolishness; [all these evil things come from within, and defile the man.] (My translation) I hope this is helpful!11/15/21

Thanks for the answer. Since they are related but not exactly the same would it be safe to say that the difference is a matter of degree?11/14/21
