On the Subject of the Imperative Mood

Many English grammarians, at home and abroad, think that there is not only the imperative with the subject of the second person, but the both one with the subject of the first and the third person. Some grammarians believe that the subject of any imperative is the addressee. The author analyzes the subject of the imperative from the semantics and thinks that the subject of any imperative is virtually in the second person.
