The word "purview" refers to the range of operation, authority, or concern that is covered by something. It typically indicates the scope or limit of what someone is responsible for, or the area within which something has influence or relevance.
The term "purview" comes from the Middle English word "purveu," which means "foreseen" or "provided for." It derives from the Old French "porveu," from the verb "porveoir," meaning "to foresee." The root can be traced back to Latin "providere," which means "to see ahead" or "to provide."
