What is the term for a law or code of laws?

The term "Canon" refers to a set of rules or a body of laws that are established by a specific authority. It is often used in the context of legal systems, religious laws, or standards in various disciplines, establishing what is considered correct or acceptable within that system. The historical usage of the word can be traced back to ecclesiastical law, but its application has broadened to include secular legal frameworks.

The other terms do not carry the same meaning. "Catharsis" pertains to emotional release or cleansing, typically related to psychological processes. "Coagulate" refers to the process of a substance, typically a liquid, transforming into a solid or semi-solid state, often used in medical contexts. "Collusion" signifies a secret agreement or cooperation for deceitful purposes, especially in a legal or competitive context. Thus, "Canon" is the most appropriate term when referring to a law or code of laws, given its direct association with established regulations and guidelines.
