Here is a learning support on writing the imperative sentence. This type of clause, as you know, issues an imperative, i.e. “the grammatical mood that expresses the will to influence the behavior of another.”
I wrote this document myself, synthesizing a variety of sources. I tried to keep this short, while integrating all the essential elements of this kind of construction–e.g. saying “please” when using an imperative sentence in speech or prose.
If you find typos in this document, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
