The term "additional charge" refers to an extra or supplementary cost that is incurred beyond what is already expected, required or customary. It can be applied in various contexts such as financial transactions, legal proceedings, and personal responsibilities. For example, if a person incurs additional expenses while traveling due to unforeseen circumstances, it would mean an extra charge over and above the original cost of the trip. In law, "additional charges" can refer to penalties or fines imposed for violations beyond those already specified by law. Similarly, in a work context, additional charges may imply taking on more responsibilities than originally assigned, leading to an increase in one's workload and potential overtime payments.
