A more thorough explanation:

The period of prescription is the amount of time set by local law that is sufficient for obtaining or extinguishing a right through the lapse of time. This means that if a person does not exercise their right within the prescribed period, they may lose it.

For example, let's say that the period of prescription for a property dispute in a certain state is 10 years. If someone has a claim to a piece of land but does not take any legal action to assert their claim within 10 years, they may lose their right to the land.

It's important to note that the period of prescription may be extended in certain circumstances, such as if the person with the right is a minor, mentally ill, or married. This means that the clock may not start ticking until the person is no longer in one of these circumstances.

Overall, the period of prescription is a legal concept that helps to ensure that people exercise their rights in a timely manner and that disputes are resolved in a fair and efficient manner.
