Usage
What is an imperative sentence? An imperative sentence is a sentence used to give commands or instructions or make requests, as in Give me that. It usually begins with a verb or a verb phrase. Imperative sentences often don’t have an apparent subject. Instead the subject is implied, usually the person who the speaker is giving the commands or instructions to. It is possible to include subjects in imperative sentences by addressing the person separately, as in Joe, hand me that wrench. While imperative sentences often start with verbs, they can also begin with adverbs, as in Carefully move the sofa, or prepositional phrases, as in Without opening your eyes, count to ten.

Etymology
Origin of imperative
First recorded in 1520–30; from Late Latin imperātivus, equivalent to Latin imperāt(us) “imposed,” past participle of imperāre “to impose, order, command” ( im- im- 1 + -perāre, combining form of parāre “to set, get ready, produce, obtain”; see prepare) + -īvus -ive
Explanation
When something absolutely has to be done and cannot be put off, use the adjective imperative. Imperative is from Latin imperare, "to command," and its original use was for a verb form expressing a command: "Do it!" is an imperative sentence. The word is still used that way, but it's more commonly applied to something so pressing it cannot be put off: "It's imperative that we hire more workers if we want to complete the job on time." Imperative has more immediate force than pressing but less than urgent.
