Definition

Something that happens or occurs in time and space.

Usage Note

An event may be caused by nature, an agent, or a combination of nature and agent. Events have temporal and spatial boundaries. An event may actively involve some agent(s) and affect any entity. An event may be discrete, happening at a specific moment in time, or may occur over an extended period of time. Events may have events as parts, and events may precede or follow one another. Multiple agents may participate in the same event, and in different roles.
