Question

Which form does a verb take when the speaker gives a command without stating the subject? passive indicative subjunctive imperative

Answer 1

imperative......................

Answer 2

That would be the imperative. Technically, the subject IS always stated albeit indirectly.

Ex.: Sit down.

While the implied (understood) subject is not directly stated, it IS indirectly stated. The listener or reader knows that the subject here is 'you.'
