Hi.
Would you help me define the following words in simplest form. Thanks.

What is Imperative sentence?
What is Passive voice?
Active voice?

[Casiopea]

What is Imperative sentence?
=> Its verb is in its base form and the sentence lacks an overt subject.

EX: Sit, please. (You) Sit, please.

What is Passive voice?
=> The verb has the form BE + ed/en (e.g., was handed), the object functions as the structural subject, and the grammatical subject is either left out or introduced with a by-phrase.

EX: The can was crushed (by the truck).
Active: The truck crushed the can.
