Passive Voice

Passive voice meaning

In the passive voice, the subject or object is acted upon by the verb rather than the subject carrying out the verb. For example:

• Passive voice = The verb acting upon the subject/object, e.g. 'The pizza was eaten before we arrived.'
• Active voice = Subject carrying out the verb, e.g. 'They ate the pizza before we arrived.'

Another way of looking at this would be to say that in the passive voice, the subject is passive. If something is passive, it doesn't do a lot, which is certainly the case in a passive sentence.

If we take the example above, we don't get to know who ate the pizza; the pizza was just eaten. Comparing this with the active voice example, we learn that 'they' ate the pizza. In this example, the subjects 'they' actively eat the pizza as opposed to the pizza being eaten.

Fig 1. The pizza was eaten, but who by?

Don't worry if this sounds a little confusing; we'll go through it more and look at some more examples as the article goes on.

Passive voice characteristics

As we've already noted, the passive voice's standout characteristic is that the verb acts upon the subject or object rather than the subject executing the action verb. This is one of the best ways to distinguish between active and passive voices.

Some other things to look for include:

• Does the sentence contain a conjugated form of the verb -to be? (for example, 'The essay has been finished.' This sentence includes the past participle of the verb -to be, 'been'.)

• Is there a past participle verb (a.k.a verb 3) in the sentence? (Past participles can be formed in a variety of ways, often by adding the suffix '-ed/d' or '-en' or, for irregular verbs, the spelling changes completely. Some examples of past participle verbs include; eaten, given, read, walked, thought, and been.

• Is there a direct or implied '-by'? (does the sentence tell us who or what is affected by the verb?)

Types of Passive Voice

There are two types of passive voice, which we'll look at in this section. These are:

• Short passive voice

• Long passive voice

Short passive voice

Short passive voice is the more commonly used of the two types of passive voice and is often referred to as the 'agentless passive'. This other name sums up nicely what the short passive voice is all about.

Essentially, the short passive voice has no agent.

For example, in the sentence 'Sally ate the pizza.', we can tell that Sally is the one who ate the pizza. Sally is the one carrying out the action in the sentence. Sally is the agent of the sentence. This sentence is written in the active voice. If we wanted to rewrite this sentence using the short passive voice, it would look something like:

In these two examples, the agent (the person or thing that carries out the action) is absent.

Long passive voice

The long passive voice is similar to a sentence using the active voice. However, the structure of long passive sentences has some key differences from active sentences.

The long passive voice is when the object becomes the subject of the sentence. What does this mean? Aren't the subject and the object the same thing? They can often be used in similar ways, but they are distinct grammatical features.

For example, if we take the same sentence as we used in the short passive voice example, 'Sally ate the pizza.' Sally is the subject of the sentence (the one carrying out the action), 'ate' is the verb or the action, and 'the pizza' is the object, the phrase controlled by the action. The 'pizza' also completed the action by answering the question: "What did Sally eat?"

That example was an instance of the active voice, but if we were to rewrite the sentence in the long passive voice, it would look something like:

With this structure, the sentence becomes long passive because the object (the pizza) has become the subject, and the previous subject (Sally) has become the object.

Passive Voice Examples

Hopefully, those breakdowns of the different types of passive voice have helped your overall understanding of the passive voice. To give you some more context, we'll now look at some more examples of each kind of passive voice.

Before we do that, here are some active voice sentences that we'll be changing into the passive voice:

• The boys threw the ball through the window.

• The President made promises.

• The roofer has replaced the tiles.

These are active sentences because they follow the typical structure of subject - verb - object (who carries out the action? - what is the action? - what is controlled by the action?)

Short Passive Voice examples

• The ball was thrown through the window.

• Promises were made.

• The tiles have been replaced.

All of these examples include a form of the verb -to be, a past participle of the verb ('throw' and 'make' are irregular verbs), and an implied '-by'. These factors make them passive voice examples.

What makes them examples of the short passive voice is that there is no agent. We cannot tell who has completed the action of each sentence.

Fig 3. Promises were made

Long passive voice examples

• The ball was thrown through the window by the boys.

• Promises were made by the President.

• The tiles have been replaced by the roofer.

All of these examples include a form of the verb -to be, a past participle, and a direct '-by' (that is, we are told who the action is carried out by, or in other words, these sentences do have an agent). These factors make them examples of the passive voice.

What makes them long passive is that the object and the subject have switched places. If you look at the active sentences at the top of this section, for example:

• The President made promises.

The subject is the President, and the object is the promises. Alternatively, in the long passive voice:

• Promises were made by the President.

The subject of the sentence is the promises, and the object is the President.

When to Use Passive Voice

As is the case with different registers and tones when writing or speaking, it is not always appropriate to use the same grammatical voice for all purposes or interactions. The passive voice has its time and place and situations where it should be avoided.

When does it make sense to use the passive voice?

• When the performer of the action is unknown - 'The accident involved two cars.'

• When you want to be vague about who the performer is - 'Mistakes were made.'

• When you're talking about a generally accepted or cliché notion - 'Rules were made to be broken.'

• When you want to place emphasis on the topic you're discussing rather than who it involves - 'Penicillin was discovered by Alexander Fleming.'

• Academic writing often uses the passive voice, e.g. 'In a study by Peter Trudgill (1974), the research found that social class had a more significant effect on non-standard language use than gender.'

Passive Voice Misuse

Just as there are appropriate times to use the passive voice, there are also times when using the passive voice can sound clumsy or is otherwise inappropriate. Some examples of passive voice misuse include:

• When someone hasn't done enough research to back up an argument - 'Sources have shown that MSG is bad for your health.' (What sources? Who says this?)

• Using multiple passive structures in one sentence, making it wordy and overly complicated, e.g. 'The Genie case study which had been undertaken by various researchers was deemed as unethical by some parties.'

• Not stating necessary specifics, making the meaning of a sentence unclear, e.g. 'Scholarships were offered by Oxford and Cambridge and eventually a scholarship was accepted by James.' (Which scholarship did James accept?)

• Teachers often tell students not to write in the passive voice as this can lead to meaning becoming lost and writing becoming clunky. Schools usually prefer for students to use the active voice when writing.
