Here's how it works:
* Imperative sentences give commands or instructions. They are typically worded as if addressed directly to the listener.
* The subject of an imperative sentence is usually "you." However, "you" is often omitted for brevity and clarity.
Example:
* Explicit subject: *You* close the door.
* Understood subject: Close the door.
The understood subject, "you," is present in the second sentence, but it's not written. It's understood from the context and the imperative form of the verb ("close").
Therefore, you can't see the understood subject in an imperative sentence, but you can infer it from the sentence's structure and context.
