What is the imperative mood in grammar?

The imperative mood in grammar refers to the verb form used to express commands, requests, or instructions. This mood directly addresses the listener and tells them what to do, typically omitting the subject "you." For example, in the command "Close the door," the verb "close" is in the imperative mood, clearly indicating an action that the speaker wants the listener to perform. This usage is distinct because it specifies a direction or command, unlike other moods that convey statements, actions, or narrative contexts. The other choices focus on different grammatical concepts that do not capture the unique function of the imperative mood.
