Having lost people's trust or respect because of being proven false or unreliable; damaged in reputation.
From Old French 'discredit' (dis- meaning 'not' + credit from Latin 'credere' meaning 'to believe'). The word literally means 'not believed' or 'not given credit.' It entered English in the 1600s as financial and reputation vocabulary expanded.
