The word canon is a noun that means a set of rules or principles that are accepted or followed or an authority list of books or texts. It can also mean any established rule or concept that everyone follows.

Again, canon refers to a particular member of the clergy or a contrapuntal musical composition.

Canon originated from the church where it means “church law.”

It changed its meaning to a “catalog of approved authors” in the 1800s. A comprehensive, accepted collection of work or connected writings is now known as the canon.

Original material or content is also known as canon. For example, if you write fan fiction about Harry Potter, the source material is official but not your fan fiction.
