Not completed or fulfilled, often referring to obligations or debts that have not been settled.

Undischarged → It is formed from "un-" (meaning not) and "discharged" (from Latin "dis-" meaning apart and "carrere" meaning to carry). The word "undischarged" means not having been released or carried away from an obligation or duty.
Think of 'not' ('un-') having been 'carried away' ('discharged') — that's why undischarged means something that has not been released.
