Passive Voice vs Active Voice

Passive Voice

Passive Voice module of essay checker
English and grammar teachers love to tell their students to use the active voice because it tends to make sentences shorter, clearer, and more impactful.

But is it a crime to write in the passive voice? Absolutely not. In many cases, the passive voice is actually preferable to the active voice. However, it does present many dangers that could make our writing wordy or unclear. Let’s define the active and passive voices, then discuss some potential problems with passive writing.

Examples of Active and Passive Voices

Whether a sentence is active or passive depends on the relationship between the verb and the subject. In the active voice, a subject performs a verb. For example:

Barry Bonds hit 762 home runs.

Barry Bonds (subject) hit (verb) 762 home runs (object).

In the passive voice, the subject is switched, so the object of the active sentence becomes the subject of the passive sentence.

762 home runs were hit by Barry Bonds.

Unlike the subject in the active voice, the subject in the passive voice does nothing. In other words, the subject, home runs, takes no action. Instead, the home runs are acted upon.

Another example of an active sentence:

My parents bought groceries for my sister’s birthday party.

The subject of the sentence, the parents, performs the action of buying groceries. The parents are the focus of the sentence.

However, in the passive voice, the subject is switched, so the object of the active sentence becomes the subject in the passive.

Groceries were bought by my parents for my sister’s birthday party.

The subject, or focus, of the sentence takes no action. Instead, the groceries are acted upon by the parents.

Problems with Passive Voice

A passive voice can create confusion; it often disrupts rhythm and makes a sentence harder to understand. In many cases, verbs and subjects become vague or ambiguous.

Evidence was presented to support the idea that homelessness is experienced by more than 600,000 people.

A couple questions: Who is presenting this evidence? And how is the number of homeless people an idea? Also, because the subject, the evidence, doesn’t perform any action, the sentence is inherently confusing.

Let’s clarify this sentence with a few simple fixes:

The U.S. Census Bureau estimated the number of homeless people at 600,000.

Here, the U.S. Census Bureau becomes the subject who drives the estimation of the number of homeless people. The focus of the sentence has shifted, creating a simple, straightforward structure. Another example:

A talk was given by the college professor; she cited a paper that said homelessness went down last year.

Again, the subject of the sentence, the “talk,” doesn’t do anything. Here, the passive voice creates a clunky break that requires a semicolon to keep the sentence grammatically correct. The subject of the first part of the sentence is the “talk,” but the talk doesn’t cite the paper, the professor does. See how confusing the subject can become in a passive sentence?

The college professor cited a paper stating homelessness decreased last year.

By changing the subject of the sentence to the doer of the action (the college professor), we get a simple, easy to read statement.

How to Identify the Passive Voice

The easiest way to identify the passive voice is to look for the following in any sentence:

passive voice = form of “to be” + past participle (verb)

A past participle is a verb that takes the past tense form. Look for it in conjunction with a form of “to be,” which usually includes words like is, are, am, was, were, has been, have been, had been, will be, will have been, and being.

Also, look for the need to attribute the perceived doer of action with the word “by.”

When the car was driven by the racer, he sped out of control and hit the guardrail.

Reasons to Use the Passive Voice

Remember, we want our writing to be clear. So when we talk about passive versus active voices, keep in mind that either voice can work, depending on the situation.

Here are a few occasions where the passive voice may be preferable to the active voice:

  1. When the agent is more important than the subject. Take the example: “My car was hit.” We want to focus on the car itself, since we care more about the car being damaged than we do about who damaged the car.
  2. When the agent of action is a secret or an authoritative figure. Take common disclaimers like “Trespassers will be prosecuted,” or “Access is denied.”
  3. When we want variety in our writing. Any kind of writing, no matter how active, tends to grow dull after awhile. Sentence rhythm and structure will feel stilted and repetitive, especially when each sentence is focused only on the drivers of action.

Effective Use of Sentence Length

The issue of sentence length leaves many writers scratching their heads. Short, long, medium length sentences - which are better? Does it make a difference? Why should we pay attention to sentence length anyway?

For one, it adds as much meaning to a text as the words you choose. Sentence length conveys a specific mood and rhythm and matches the actions being described. For example, if you were writing a tense car race, shorter sentences may help heighten the suspense of the scene. On the other hand, longer sentences may work better when writing about complex philosophical abstractions.

Let’s look at a couple examples.

“As the number one car slammed its brakes around the turn, my foot hit the gas, and I swung around him, crossing the finish line and winning the race.”

It’s not bad, but let’s see what happens when we break it up into several sentences.

“The number one car slammed its brakes around the turn. My foot hit the gas, and I swung around him. I crossed the finish line, winning the race.”

We find that shorter sentences help tighten the action, accentuating the descriptions of “slamming the brakes,” “hitting the gas” and “crossing the finish line.”

Other texts may demand longer sentences:

“Descartes stated that the mind is mental. The body is physical. Mind and body are, therefore, not identical. This is the mind-body problem.

Philosophical problems are often complex and may work better with longer sentences and more description:

“Descartes stated that since the mind is mental and the body physical, the two cannot be identical. This dilemma is known as the mind-body problem.”

See how much clearer this version reads? The longer sentence length creates a nice, flowing structure that leads logically from one idea to the next.

Let’s look at more examples in which short and long sentences can be problematic, followed by some strategies for correcting them.

Short Sentences

Short sentences are useful for supplying small bits of information. They cut to the chase and emphasize one, maybe two, points. But, their stop-and-start rhythms can make them difficult to read:

“Short sentences are hard to read. They stop and start. What happens when you read them? You feel like you’re stuttering. They break up the thought process. Sometimes they’re useful. Other times they’re not. They’re frustrating. Right?”

How do we stretch out these short sentences so they’re not so clunky? Try lengthening them with conjunctions, which are words that join two sentences, or independent clauses, together.

Specifically, let’s look at coordinating and subordinating conjunctions. Coordinating conjunctions include words like and, but, or, nor, for, yet and so. Common subordinating conjunctions include although, because, once, unless, wherever and many, many more. Read a complete list of them here.

Let’s rework our short-sentence paragraph:

“Short sentences are hard to read because they stop and start, making you feel like you’re stuttering. Although they’re useful for breaking up the thought process, they can be quite frustrating to read. What do you think?”

See how conjunctions create a simple chain of ideas to help round out the sentences’ rhythms? Try using them the next time you find yourself writing sentences that are too short or do not reflect the proper mood.

Long Sentences

Long sentences provide more detail and information than shorter sentences and are used to investigate in-depth ideas. However, they, too, can be problematic, for repeated use of long sentences can bore the reader. They may also become difficult to read, since the reader must hold several ideas in his or her head at once.

Let’s look at an example of a long, somewhat complicated sentence:

“Although I prefer to write long sentences, they are also problematic, as they quickly become boring and long-winded; in turn, their inherent difficulty can disengage the reader, causing him or her to stop reading.”

It’s not a completely terrible sentence, but it is long, complex and may be more effective if we break it up into several sentences:

“Although I prefer to write long sentences, they quickly become boring and long-winded. They’re also difficult to read and may cause the reader to stop reading.”

See how our points become sharper? Instead of five or six ideas, each sentence contains two, making them easily digestible.

Readability Indices

It’s widely known that easy and enjoyable reading helps learning and comprehension. Most people prefer reading “plain English,” and tend to turn off when a passage is too difficult to read. So when we speak of a text’s readability score, or of a readability index, what we mean is: How easy is it for readers to understand?

Measuring readability is important for a number of reasons. For one, teachers need to know if their students are capable of writing at their grade level, or whether they need more schooling in a particular area. Readability scores also help teachers and school systems grade whether a textbook is right for their students.  

Writers also need readability scores - especially those who write for children and pre-teens. They’ve definitely helped me make sure I’m writing for the correct audience; plus, they’ve taught me how to increase or decrease my usage of complex sentences depending on my readership. Never write outside your audience!

PaperRater Premium-Only Module: Readability Scores

PaperRater is proud to offer a NEW series of twelve readability scores as part of our premium service. Just sign in, visit our proofreader, enter your text, and receive a full, side-by-side comparison of the most common readability indices.

Why do you offer twelve indices? Shouldn’t I use just one?

Each readability index uses different criteria to create a score. As you’ll see, some use input based on syllables, and others based on word length. Plus, the equations used are slightly different.

So we give our users a set of twelve to eliminate bias and to provide you a wider range of input. That way you can choose for yourself which ones you want to incorporate into your work.

Here’s a quick breakdown of each index we provide:

Automated Readability Index (ARI)

The ARI grades text based on a combination of word and sentence structure. Computers find it difficult to analyze syllables, so the ARI uses a formula based on the number of characters per word, although it’s debatable whether counting characters or syllables is more helpful.

Coleman-Liau Index

Creators Meri Coleman and T. L. Liau constructed this readability score for the Office of Education to standardize textbooks in the United States. Like the ARI, it operates on the assumption that characters per word is a better indicator of readability than syllables. From Wikipedia: “L is the average number of letters per 100 words and S is the average number of sentences per 100 words.”

Dale-Chall Readability Formula

The Dale-Chall Readability Formula uses a different kind of input. Instead of using the number of characters in a word, it calculates the approximate grade level of a text by measuring “hard words.”

What exactly are hard words? The Dale-Chall list contains a list of about 3,000 words known by at least eighty percent of the children in the fifth grade. Words considered difficult are those not listed. The higher the score, the higher the text’s grade level.

Flesch Reading Ease
Unlike the first two indices, the Flesch Reading Ease calculates readability by the average sentence length and the average number of syllables per word. Text is rated on a scale from one to a hundred; the lower the score, the harder the text is to read. Plain English is set at 65, with the average word containing two syllables. The average sentence contains 15 to 20 words.

By the way, the above passage received a score of 73.7 on the Flesch Reading Ease, which means it’s slightly easier to read than plain English.

Flesch-Kincaid Grade Level

The Flesch-Kincaid Grade Level is a companion index to the Flesch Reading Ease, and uses the same inputs (average sentence length + average number of syllables per word). However, the measurements are weighted differently, and so it produces a score as an approximate grade level (e.g. 1-12, or higher).

Fry Readability Formula

Instead of taking a complete word count, the Fry Readability Formula randomly chooses three 100-word samples throughout the text. It then counts the average number of syllables and the average number of sentences per hundred words, and plots them onto a graph. The intersection of the two averages represents the appropriate reading level. It is used widely in the healthcare industries.

Gunning Fog Index

The Gunning Fog Index is calculated by the average length of a sentence and the percentage of complex words. Its inventor, Robert Gunning, complained that then-current writing was too complex (had too much fog) and needed to be simplified. Complex words in this case are described as having three or more syllables. Yet while complex words can be a good indicator of readability, it fails to account for the fact that words with three or more syllables are not necessarily difficult to comprehend.


LIX, or the Lasbarhetsindex Swedish Readability Formula, was specially designed for the readability of texts in foreign languages. Its formula uses (a) the number of words; (b) the number of periods; and (c) the number of long words (more than six letters). Multicultural teachers prefer its emphasis on long words and average sentence length to predict readability.

\text{LIX} = \frac{A}{B} + \frac{C \cdot 100}{A}

Linsear Write

Similar to the Flesch readability indices, Linsear Write helps calculate a text’s readability by sentence length and the number of “hard words” - words with three or more syllables. It was adopted by the U.S. Air Force to grade the readability of their flight manuals.

Raygor Estimate Graph

A simple readability estimate, the Raygor Estimate allows you to calculate an approximate grade level by taking 100 words from your text and counting the number of sentences. Then you count the number of words within your sample that contain six or more letters. Plot your points on the graph below, and you will receive an approximate U.S. grade level.


SMOG is a playful acronym for “Simple Measure of Gobbledygook,” and was developed as a replacement for the Gunning fog index. It is estimated by taking three 10-sentence samples from a piece of text, counting the words with three or more syllables, estimating the square root of the number of words, then adding three.

Spache Readability Formula

This formula was designed for third-grade texts or below, comparing the amount of “unfamiliar words” to the number of words per sentence. “Unfamiliar words,” in this case, are determined to be words that those in third grade or below do not understand. It is recommended to use the Space Readability Formula for those in third grade or below, and to use the Dale-Chall Readability Formula for those in fourth grade or above.
