Academia Teach: Grammar: Passive Voice

Introduction to Passive Voice

The passive voice is used when the focus is on the action or the object of the action rather than who or what is performing the action. It can be particularly useful for formal writing, scientific reports, or when the doer of the action is unknown or unimportant.

Forming the Passive Voice

The passive voice is formed by combining a form of the verb "to be" with the past participle of the main verb. The structure is:

Subject + form of "to be" + past participle (+ by agent)

Examples:

• Active: The chef prepares the meal.

• Passive: The meal is prepared by the chef.
