This compound verb means to accuse or charge beforehand, to make a prior allegation. In Romans 3:9, Paul asks whether Jews have any advantage, answering that he has already charged (accused beforehand) that both Jews and Greeks are all under sin. The 'beforehand' refers to his previous argumentation in chapters 1-2 where he established universal human sinfulness. The term emphasizes that this indictment isn't new but already demonstrated.
