When Should You Use Active vs. Passive Voice?

 One of the fundamental choices every writer faces is whether to use the active or passive voice in their sentences. Both voices serve important functions in communication, but knowing when to use each can greatly improve the clarity, tone, and effectiveness of your writing.

This article explores the differences between active and passive voice, discusses the strengths and appropriate uses of each, and provides guidance on making the best choice for your writing purpose. Whether you write academic papers, business reports, creative stories, or everyday emails, mastering voice usage will enhance your communication skills.

Understanding Active and Passive Voice

Before diving into when to use each voice, let's quickly review what they are:

• Active voice: The subject performs the action expressed by the verb.
  Example: The researcher conducted the experiment.
  (The researcher is the subject actively doing something.)

• Passive voice: The subject receives the action. The doer of the action may be omitted or mentioned after the verb using “by.”
  Example: The experiment was conducted by the researcher.
  (The experiment is the subject receiving the action.)

When to Use Active Voice

Active voice is generally preferred in writing for several reasons:

1. Clarity and Directness

Active sentences clearly identify the doer and the action, making statements straightforward and easy to understand.

• Active: The manager approved the budget.

• Passive: The budget was approved by the manager.

The active version tells you exactly who did what without ambiguity.

2. Conciseness

Active sentences tend to be shorter and less wordy, which keeps the writing tight and engaging.

3. Engagement and Energy

Active voice often sounds more dynamic and lively, making your writing more compelling.

4. Standard in Most Writing Styles

In journalism, business writing, and many academic disciplines, active voice is the norm because it promotes clarity and accountability.

When to Use Passive Voice

Despite the advantages of active voice, passive voice has important and legitimate uses:

1. When the Doer Is Unknown or Irrelevant

If who performed the action is unknown or unimportant, passive voice can focus on the action or the recipient.

• The window was broken last night.
  (We don’t know or need to specify who broke it.)

2. To Emphasize the Action or Receiver

Sometimes the emphasis should be on the result or the person/thing affected, not the actor.

• The vaccine was developed in record time.
  (The focus is on the vaccine and its development, not the developers.)

3. To Maintain Objectivity

In scientific or technical writing, passive voice is often used to maintain a neutral tone by focusing on processes and results rather than on the researchers.

• The samples were tested under controlled conditions.

4. Politeness or Formality

Passive constructions can soften statements, especially in situations requiring diplomacy or indirectness.

• Mistakes were made during the process.
  (This avoids blaming a specific individual.)

Examples Illustrating Appropriate Use of Each Voice

Situation	Active Voice Example	Passive Voice Example
Clear subject doing a clear action	The chef prepared the meal.	The meal was prepared by the chef.
Unknown doer or irrelevant actor	(Not applicable; no active form without subject)	The documents were signed yesterday.
Scientific writing or objective tone	We measured the temperature at noon.	The temperature was measured at noon.
Emphasizing the recipient of an action	The committee approved the proposal.	The proposal was approved by the committee.
Politeness or indirectness	You made an error in the report.	An error was made in the report.

Tips for Choosing Between Active and Passive Voice

• Ask what you want to emphasize: The doer (active) or the receiver/action (passive)?

• Consider your audience: Business and academic readers usually prefer active voice for clarity.

• Match the tone and style: Use passive voice for formal, objective, or diplomatic writing.

• Avoid overusing passive voice: Excessive passive voice can make writing vague and cumbersome.

How to Balance Active and Passive Voice

Good writing often involves a balance between active and passive voice. Use active voice by default, but do not hesitate to use passive voice when it serves a clear purpose, such as emphasizing the action or maintaining objectivity.

Conclusion

Knowing when to use active versus passive voice is a key skill for effective writing. Active voice promotes clarity, brevity, and engagement, making it the preferred choice in most contexts. Passive voice, on the other hand, is valuable when the actor is unknown, irrelevant, or when the focus needs to be on the action or receiver.

By understanding the strengths of each voice and the contexts where they work best, you can craft writing that is both clear and stylistically appropriate. Whether you are drafting a report, writing an essay, or composing a formal letter, making the right voice choice enhances communication and helps your message resonate with your audience.
