A payment that is less than what is required or expected.
The company faced legal issues due to the underpayment of its employees.
Underpayment → It is formed from "under-" (meaning below or insufficient) and "payment" (from Old French *paiment*, meaning the act of paying). The word refers to a payment that is below the required or expected amount.
Think of 'under-' meaning below, and 'payment' referring to the act of paying. This helps you remember that underpayment means a payment that is insufficient or below what is expected.
