Which type of sentences provides commands or requests?

The type of sentences that provides commands or requests is imperative sentences. These sentences are designed to direct someone to perform an action, often beginning with a verb. For example, in the sentence "Please close the door," the word "close" is a verb that instructs the listener to take action.

Imperative sentences can also express requests politely, as in "Could you help me?" In these instances, the subject ("you") is usually implied rather than stated outright.

Understanding that imperative sentences focus on directing behavior is crucial for recognizing their purpose in communication, distinguishing them clearly from other sentence types that serve different functions, such as expressing statements, asking questions, or conveying strong emotions.
