The passive voice is a grammatical construction used to shift the focus from the person or thing performing an action to the object or person receiving it. You should use it in formal, scientific, or academic writing; when the doer of the action is unknown or unimportant; or to create an objective, impersonal tone.
Many English learners are told to avoid the passive voice, but this advice is incomplete. While the active voice is often more direct and energetic, mastering how and when to use the passive voice is a key skill that adds precision and sophistication to your writing. This guide will break down what it is, when it's appropriate, and how to form it correctly.
What's the Difference Between Active and Passive Voice?
Before we dive into the rules, let's clarify the fundamental difference in sentence structure. Understanding this is the first step to choosing the right voice for your purpose.
- Active Voice: The subject of the sentence performs the action. The structure is clear and direct: Subject (Doer) + Verb + Object (Receiver).
- *Example:* The team developed a new app.
- Passive Voice: The subject of the sentence receives the action. The doer is either moved to the end of the sentence or left out entirely. The structure is: Subject (Receiver) + Form of 'to be' + Past Participle (+ by + Doer).
- *Example:* A new app was developed by the team.
Notice how the focus shifts from "the team" to "a new app."
How and When to Use the Passive Voice Correctly
So, when is it actually a good idea to use the passive voice? While the active voice is the default for most writing (like emails and stories), the passive voice is a powerful tool in specific situations.
Here are the four most common and acceptable times to use it:
- When the Actor is Unknown or Unimportant
If you don't know who performed the action, or if it doesn't matter, the passive voice is your best choice. The focus is on the event itself.
- *Example:* My wallet was stolen yesterday. (We don't know who the thief is.)
- *Example:* The invitations have been sent. (Who sent them is less important than the fact they are on their way.)
- To Emphasise the Recipient of the Action
Sometimes, the thing that was acted upon is more important than the actor. The passive voice brings the most important noun to the front of the sentence.
- *Example:* The Nobel Prize in Physics was awarded to three scientists for their work on quantum mechanics. (The prize is the focus.)
- *Example:* This symphony was composed in the 18th century. (The symphony is more important than the unnamed composer in this context.)
- In Scientific, Academic, or Formal Writing
The passive voice creates an objective and impersonal tone, which is ideal for scientific reports, academic papers, and other formal documents. It focuses on the process and results rather than the person who performed the work.
- *Example:* The water samples were collected over a period of three weeks.
- *Example:* It is believed that the new policy will have a positive impact.
- To Avoid Assigning Blame or Sounding Accusatory
In professional or delicate situations, the passive voice can be a more diplomatic way to point out an issue without directly blaming an individual.
- *Example:* A mistake was made in the report. (This is softer than saying, "You made a mistake.")
How Do I Form the Passive Voice?
Forming the passive voice is a straightforward process. It always involves a form of the verb "to be" (am, is, are, was, were, been, being) followed by the past participle of the main verb (e.g., written, taken, built).
Here’s the step-by-step transformation:
- Active: The company will launch the product.
- Object becomes the new subject: *the product*
- Add the 'to be' verb (matching the original tense): *will be*
- Add the past participle of the main verb: *launched*
- (Optional) Add the original subject with 'by': *by the company*
- Passive: The product will be launched by the company.
When Should I Avoid the Passive Voice?
While useful, the passive voice can make your writing feel weak, vague, and unnecessarily wordy if overused. For most everyday writing, like blog posts, emails, and fiction, the active voice is stronger, more concise, and more engaging.
- Weak and Wordy (Passive): The reason the meeting was cancelled by the manager was that the report had not been finished.
- Strong and Direct (Active): The manager cancelled the meeting because the team hadn't finished the report.
Conclusion: A Tool, Not a Mistake
Ultimately, the passive voice isn't a grammatical error; it's a stylistic choice with a specific job. By understanding how and when to use the passive voice, you can make your English writing more precise, formal, and effective. The key is to use it deliberately, not accidentally. When you choose the passive voice, make sure you have a clear reason for shifting the focus away from the doer of the action.
Frequently Asked Questions (FAQ)
Q1: Is using the passive voice a grammar mistake? No, it is not a grammar mistake. It is a valid grammatical construction. However, overusing it or using it in the wrong context (like creative writing) can be considered poor style because it can make sentences less direct and energetic.
Q2: Can you give an example of passive voice in a news headline? Yes. News headlines often use the passive voice when the perpetrator is unknown or the event itself is the main news. For example: "Historic Downtown Building Damaged in Fire" or "New Space Telescope Launched Successfully."
Q3: Why is the passive voice used so much in academic writing? Academic and scientific writing prioritises objectivity. Using the passive voice helps remove the researcher from the narrative (e.g., "the sample was heated" instead of "I heated the sample"), placing the focus squarely on the experiment, data, or process being described.
Q4: How can I easily spot the passive voice in a sentence? The quickest way to identify the passive voice is to look for a two-part verb phrase: a form of the verb "to be" (is, are, was, were, been) immediately followed by a past participle (a verb that often, but not always, ends in -ed or -en). Examples include "was written," "is being considered," and "have been seen."
