A more thorough explanation:

Definition: A layman is someone who is not a member of the clergy.

Example: John is a layman and does not have any religious training or authority to perform religious ceremonies.

Explanation: The example illustrates that John is not a member of the clergy, meaning he is not a priest, minister, or any other religious leader who has been trained and authorized to perform religious ceremonies. As a layman, John does not have the same religious authority or responsibilities as a member of the clergy.
