What is an imperative sentence used for?

An imperative sentence is used to issue commands, instructions, or requests. Its primary function is to tell someone what to do, making it a direct and clear form of communication. For example, if someone says, "Close the door," they are providing a specific directive that the listener is expected to follow.

Imperative sentences can be straightforward commands, polite requests, or even suggestions, but they all share the common goal of guiding the actions of others. This distinguishes them from other types of sentences, such as those that ask questions, express desires or wishes, or state facts, which serve different communicative purposes.
