A more thorough explanation:

A warden is a person who is in charge of something. This can be a game warden who is in charge of protecting wildlife, a port warden who is in charge of managing a port, or a prison warden who is in charge of a prison or jail.

For example, a prison warden is responsible for overseeing the daily operations of a prison, including managing the staff, ensuring the safety of the inmates, and enforcing the rules and regulations of the facility. A game warden, on the other hand, is responsible for protecting wildlife and enforcing hunting and fishing laws.

Overall, a warden is a person who has a lot of responsibility and authority over a specific area or group of people.
