A more thorough explanation:

Relevancy

The fact or quality of being relevant, meaning having a connection or importance to the topic or issue being discussed.

For example, in a court case, evidence that is relevant to the case is admissible, while evidence that is not relevant is not allowed. In a job interview, relevant experience and skills are important to discuss, while irrelevant information is not helpful.

These examples illustrate how relevancy is important in determining what information is useful and appropriate in a given situation. It helps to focus on what is important and avoid distractions or irrelevant details.
