Passive voice is a grammatical construction in which the subject of a sentence receives the action of the verb, rather than performing the action.
For example in active voice we will say. “John plays football”. (In this sentence we are told what someone or something does, John is the subject of the sentence since it is performing an action)
The passive voice of the same sentence is” Football is played by John”( In this sentence we are told what is done to someone or something; the object is the subject in this sentence)
Changing the voice, like changing from Active to Passive voice or from Passive to active voice is an important question in all school grade levels. Here is a present indefinite tense active to passive voice quiz with immediate feedback.
