Passive voice is a form of sentence that the receiver of an action is mainly focused on.
Generally, we use an active voice that focuses on the person or thing does the action.
Sometimes, we want to focus the object in a sentence or the receiver of the action of verb so we use the passive voice form in the sentence.
This is the form of passive voice
Subject + v. to be + V3 ( past participle)
This example below shows the comparison form of active voice and passive voice.
A ( stands for active voice)
P ( stands for passive voice)
Yai eats an apple. (A)
An apple is eaten by Yai (P)
You can see that apple ,the receiver of the action "eat", is changed to be the subject.
