A more thorough explanation:

Definition: Irrelevance is the quality or state of being not applicable or important to a matter that is being considered.

For example, if a lawyer is presenting evidence in a court case, any information that does not relate to the case is considered irrelevant and cannot be used as evidence. Similarly, if a student is writing an essay on a specific topic, any information that does not support the main argument is irrelevant and should not be included.

Irrelevance can also refer to something that is not significant or meaningful in a particular context. For instance, if someone is discussing the latest fashion trends, a discussion about the weather would be irrelevant.
