An action’s type essentially tells you how long the action takes to perform (within the framework of the 6-second combat round) and how movement is treated. There are five types of actions: standard actions, move actions, full-round actions, free actions, and swift actions. In a normal round, you can perform a standard action and a move action, or you can perform a full-round action. You can also perform one or more free actions. You can always take a move action in place of a standard action. In some situations (such as in a surprise round), you may be limited to taking only a single move action or standard action.
