A more thorough explanation:

Definition: Remedial is an adjective that describes something that provides a solution or a way to fix a problem. It can also refer to something that is intended to correct a mistake or a fault.

Examples:

• A remedial action was taken to clean up the pollution in the river.
• The school offered remedial classes to help students who were struggling with math.
• The government passed a remedial statute to address the issue of discrimination in the workplace.

The first example shows how a remedial action was taken to fix a problem, in this case, pollution in the river. The second example illustrates how remedial classes were offered to help students who were struggling with math, providing a solution to their academic difficulties. The third example shows how a remedial statute was passed to correct a fault, in this case, discrimination in the workplace.
