English passive voice
In English, the passive voice is marked by using be or get followed by a past participle. For example:
The recipient of a sentence's action is referred to as the patient. In sentences using the active voice, the subject is the of the action—referred to as the agent. Above, the agent is omitted entirely, but it may also be included adjunctively while maintaining the passive voice:
The initial examples rewritten in the active voice yield:
The English passive voice typically involves forms of the verbs to be or to get followed by a passive participle as the subject complement—sometimes referred to as a passive verb.
English allows a number of additional passive constructions that are not possible in many other languages with analogous passive formations to the above. A sentence's indirect object may be promoted to the subject position—e.g. Tom was given a bag. Similarly, the complement of a preposition may be promoted, leaving a stranded preposition—e.g. Sue was operated on.
The English passive voice is used less often than the active voice, but frequency varies according to the writer's style and the given field of writing. Contemporary style guides discourage excessive use of the passive voice but generally consider it to be acceptable in certain situations, such as when the patient is the topic of the sentence, when the agent is unimportant and therefore omitted, or when the agent is placed near the end of a sentence as a means of emphasis.
Identifying the English passive
The passive voice is a specific grammatical construction. The essential components, in English, are a form of the stative verb be and the past participle of the verb denoting the action. The agent may be specified using a prepositional phrase with the preposition by, but this is optional.It can be used in a number of different grammatical contexts; for instance, in declarative, interrogative, and imperative clauses:
- "Kennedy was assassinated in 1963."
- "Mistakes were made."
- "The window got broken."
- "Have you ever been kicked by an elephant?"
- "Don't get killed."
- "Being attacked by Geoffrey Howe was like being savaged by a dead sheep."
Misuse of the term
Though the passive can be used for the purpose of concealing the agent, this is not a valid way of identifying the passive, and many other grammatical constructions can be used to accomplish this. Not every expression that serves to take focus away from the performer of an action is an instance of passive voice. For instance, "There were mistakes" and "Mistakes occurred" are both in the active voice. Occasionally, authors express recommendations about use of the passive unclearly or misapply the term "passive voice" to include sentences of this type. An example of this incorrect usage can be found in the following extract from an article from The New Yorker about Bernard Madoff :The intransitive verbs would end and began are in fact ergative verbs in the active voice. Although the speaker may be using words in a manner that diverts responsibility from him, this is not being accomplished by use of passive voice.
Reasons for using the passive voice
The passive voice can be used without referring to the agent of an action; it may therefore be used when the agent is unknown or unimportant, or the speaker does not wish to mention the agent.- Three stores were robbed last night.
- A new cancer drug has been discovered.
- Mistakes have been made on this project.
Nonetheless, the passive voice can be complemented by an element that identifies the agent, usually via a by-phrase that is intended to emphasize the agent. For example:
- Don't you see? The patient was murdered by his own doctor!
- My taxi hit an old lady.
- My mother was hit by a taxi.
- The breakthrough was achieved by Burlingame and Evans, two researchers in the university's genetic engineering lab.
Style advice
Advice against the passive voice
Many language critics and language-usage manuals discourage use of the passive voice. This advice is not usually found in older guides, emerging only in the first half of the twentieth century. In 1916, the British writer Arthur Quiller-Couch criticized this grammatical voice:Two years later, in the original 1918 edition of The Elements of Style, Cornell University Professor of English Strunk, Jr.">William Strunk, Jr.">Strunk, Jr. warned against excessive use of the passive voice:
In 1926, in A Dictionary of Modern English Usage, Henry Watson Fowler recommended against transforming active voice forms into passive voice forms, because doing so "......sometimes leads to bad grammar, false idiom, or clumsiness."
In 1946, in the essay "Politics and the English Language", George Orwell recommended the active voice as an elementary principle of composition: "Never use the passive where you can use the active."
The Columbia Guide to Standard American English states that:
Use of the passive is more prevalent in scientific writing, but publishers of some scientific publications, such as Nature, Science and the Institute of [Electrical and Electronics Engineers|IEEE], explicitly encourage their authors to use active voice.
The principal criticism against the passive voice is its potential for evasion of responsibility. This is because a passive clause may be used to omit the agent even where it is important:
- We had hoped to report on this problem, but the data were inadvertently deleted from our files.
Advice by style guides and grammarians on appropriate use of the passive voice
Jan Freeman, a columnist for The Boston Globe, said that the passive voice does have its uses, and that "all good writers use the passive voice."Passive writing is not necessarily slack and indirect. Many famously vigorous passages use the passive voice, as in these examples with the passive verbs italicized:
- Every valley shall be exalted, and every mountain and hill shall be made low; and the crooked shall be made straight, and the rough places plain.
- Now is the winter of our discontent / Made glorious summer by this sun of York.
- We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
- Never in the field of human conflict was so much owed by so many to so few.
- Yesterday, December 7, 1941 - a date which will live in infamy - the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.
- For of those to whom much is given, much is required.
Another advisor, Joseph M. Williams, who has written several books on style, states with greater clarity that the passive is often the better choice. According to Williams, the choice between active and passive depends on the answers to three questions:
- "Must the reader know who is responsible for the action?"
- "Would the active or passive verb help your readers move more smoothly from one sentence to the next?
- "Would the active or passive give readers a more consistent and appropriate point of view?"
- "When the actor is unimportant."
- "When the actor is unknown."
- "When you want to hide the actor's identity."
- "When you need to put the punch word at the end of the sentence."
- "When the focus of the sentence is on the thing being acted on."
- "When the passive simply sounds better."
- The child was struck by the car.
- The store was robbed last night.
- Plows should not be kept in the garage.
- Kennedy was elected president.
Despite criticism that the passive can be used to hide responsibility by omitting the agent, the passive can also be used to emphasize the agent. Writers have preferred placing the agent at the end of a clause or sentence to give it greater emphasis, as in the examples given in the previous section:
- Don't you see? The patient was murdered by his own doctor!
- The breakthrough was achieved by Burlingame and Evans, two researchers in the university's genetic engineering lab.
Actual use of the passive voice
Agentless passives were once common in scientific writing, where the agent may be irrelevant, although at least one publisher considers this a "fading practice":- The mixture was heated to 300 °C.
A statistical study of a variety of periodicals found a maximum incidence of 13 percent passive constructions. Despite Orwell's advice to avoid the passive, his Politics and the English Language employs passive voice for about 20 percent of its constructions.
The Longman Grammar of Spoken and Written English gives the following rough frequencies per million words:
In academic prose, passives make up roughly 25% of all finite clauses, 15% in news, less in fiction, and even less in conversation.
Passive constructions
Canonical passives
In the most commonly considered type of passive clause, a form of the verb be is used as an auxiliary together with the past participle of a transitive verb; that verb is missing its direct object, and the patient of the action is denoted instead by the subject of the clause. For example, the active clause:- John threw the ball.
- The ball was thrown.
- The ball was thrown by John.
- Bob was hit by the ball.
- Bob got hit by the ball.
- The food is being served.
- The stadium will have been built by next January.
- I would have got/gotten 'injured if I had stayed in my place.
- It isn't nice to be insulted.
- Having been humiliated', he left the stage.
Promotion of indirect objects
Unlike some other languages, English also allows passive clauses in which an indirect object, rather than a direct object, is promoted to the subject. For example:- John gave Mary a book. → Mary was given a book.
It is normally only the first-appearing object that can be promoted; promotion of the indirect object takes place from a construction in which it precedes the direct object, whereas promotion of the direct object in such cases takes place from a construction in which the indirect object follows the direct object. For example:
- John gave Mary a book. → Mary was given a book.
- John gave a book to Mary. → A book was given to Mary.
Prepositional passive
It is also possible, in some cases, to promote the object of a preposition. This may be called the prepositional passive, or sometimes the pseudopassive.- They talked about the problem. → The problem was talked about.
The prepositional passive is common, especially in informal English. However some potential uses are much less acceptable than others; compare the following examples:
- Someone has slept in this bottom bunk. → This bottom bunk has been slept in.
- Someone has slept above this bottom bunk. → ??This bottom bunk has been slept above.
It is not usually possible to promote a prepositional object if the verb also has a direct object; any passive rendering of the sentence must instead promote the direct object. For example:
- Someone has put a child in this bunk. → *This bunk has been put a child in.
- Someone has put a child in this bunk. → A child has been put in this bunk.
- I feel people have taken advantage of me. → I feel I have been taken advantage of.
Stative and adjectival uses
A type of clause that is similar or identical in form to the passive clauses described above has the past participle used to denote not an action, but a state being the result of an action. For example, the sentence The window was broken may have two different meanings and might be ambiguous:- The window was broken, i.e. Someone or something broke the window.
- The window was broken, i.e. The window was not intact.
The ambiguity in such sentences arises because the verb be is used in English both as the passive auxiliary and as the ordinary copular verb for linking to predicate adjectives. When get is used to form the passive, there is no ambiguity: The window got broken cannot have a stative meaning. If a distinct adjective exists for the purpose of expressing the state, then the past participle is less likely to be used for that purpose; this is the case with the verb open and the adjective open, so the sentence The door was opened more likely refers to the action than to the state since one can simply say The door was open in the stative case.
Past participles of transitive verbs can also be used as adjectives, and the participles used in the above-mentioned "stative" constructions are often considered to be adjectival. Such constructions may then also be called adjectival passives. For example:
- She was relieved to find her car.
When the verb being put into the passive voice is a stative verb anyway, the distinctions between uses of the past participle become less clear, since the canonical passive already has a stative meaning. However it is sometimes possible to impart a dynamic meaning using get as the auxiliary, as in get known with the meaning "become known".
Passive constructions without an exactly corresponding active
Some passive constructions are not derived exactly from a corresponding active construction in the ways described above. This is particularly the case with sentences containing content clauses. Given a sentence in which the role of direct object is played by such a clause, for example- They say he cheats.
- It is said that he cheats.
- They say that he cheats. → He is said to cheat.
- They think that I am dying. → I am thought to be dying.
- They report that she came back / has come back. → She is reported to have come back.
- They say that she will resign. → e.g. She is said to be going to resign.
- He was rumored to be a war veteran. / It was rumored that he was a war veteran.
Another situation in which the passive uses a different construction than the active involves the verb make, meaning "compel". When this verb is used in the active voice it takes the bare infinitive, but in the passive voice it takes the to-infinitive. For example:
- They made Jane attend classes.
- Jane was made to attend classes.
Double passives
The construction called double passive can arise when one verb appears in the to-infinitive as the complement of another verb.If the first verb takes a direct object ahead of the infinitive complement, then the passive voice may be used independently for either or both of the verbs:
- We expect you to complete the project.
- You are expected to complete the project.
- We expect the project to be completed.
- The project is expected to be completed.
Similar constructions sometimes occur, however, when the first verb is raising-to-subject rather than raising-to-object – that is, when there is no object before the infinitive complement. For example, with attempt, the active voice construction is simply We attempted to complete the project. A double passive formed from that sentence would be:
- The project was attempted to be completed.
This latter double passive construction is criticized as questionable both grammatically and stylistically. Fowler calls it "clumsy and incorrect", suggesting that it springs from false analogy with the former type of double passive, though conceding its usefulness in some legal and quasi-legal language. Other verbs mentioned with which the construction is found include begin, desire, hope, propose, seek and threaten. Similarly, The American Heritage Book of English Usage declares this construction unacceptable. It nonetheless occurs in practice in a variety of contexts.
Additional passive constructions
Certain other constructions are sometimes classed as passives. The following types are mentioned by Pullum.A bare passive clause is similar to a typical passive clause, but without the passive auxiliary verb. These can be used in such contexts as newspaper headlines:
- City hall damaged by hail
- Our work done, we made our way back home.
- That said, there are also other considerations.
- I had my car cleaned by a professional.
- Jane had her car stolen last week.
- You ought to get that lump looked at.
- This software comes pre-installed by the manufacturer.
- Your car needs washing.
- That rash needs looking at by a specialist.
- Your hair needs cutting by a professional.
- You need your hair cutting by a professional.
Syntactic components of the passive voice
The sections below discuss some generalizations that linguists have attempted to identify regarding the syntactical distinctions between the passive voice, active past tense, the passive middle voice, and other past tense formations.The passive participle
In English, the passive requires the use of the past participle of a verb, generally with an auxiliary verb be. The passive uses an auxiliary be in order to get tense because participles are non finite. The participle verb is also unable to assign Case. Case is a tool used in transformational grammar that states that Case gives grammatical relations to a noun to show how it functions in the sentence; for example, if a noun needs to be in first or second person due to the form of the verb. So, if a noun phrase in the passive needs to get Case from the participle verb, it must undergo movement to the head of the sentence CP to receive nominative Case.iiWanner argues that identification of the passive voice construction can't solely rely on the auxiliary be and the past participle as distinguishing features because the auxiliary be is also used to express the progressive aspect and the past participle can be found in multiple constructions that are not passive voice constructions. In these instances Wanner refers to, the auxiliary be is not found next to or with the past participle. If the auxiliary be is present directly in front of a past participle, it is a passive construction.
External argument, implicit argument, and theta roles
Passives always contain an external argument. An external argument is specifically referring to the theta role that is assigned to the subject of the sentence. Often, the external argument is the agent of the sentence. In passive constructions, the external argument does not need to be in subject position, as seen in active constructions. It is often found in an adjunct position instead. The passive voice also doesn't have to use the agent role. The passive allows for a variety of thematic roles in the external argument. For example, the subject could have a theta role of goal instead, as in the sentence below.- I was sent a letter by them.
When a by phrase is missing in the passive, the external argument of the verb can become an implicit argument. Implicit here refers to the fact that these arguments can be implied and are not required to be explicit when used in a passive construction.
Control and arguments
Explicit arguments can control a PRO subject within an adjunct purpose clause using thematic control. PRO can also be controlled by an internal or external argument. Specifically, explicit and implicit arguments can control PRO in purpose clauses:- Theyi sold the books .
- The books were sold IMPi .
Control abilities can also be limited with implicit arguments in the passive. An implicit subject cannot control PRO in the case of ditransitive and subject control verbs. This is related to passive movement. Due to the raising done to get nominative case, the head T is no longer in an Agree relationship with the implicit subject, which means that the implicit subject can no longer control PRO either.
- Sarah was promised
- Sarahi was persuaded .
''By'' phrases in the passive
Another feature of the passive is the optional by phrase. The by phrase is where the external argument can be explicitly expressed. This by phrase acts as an adjunct to the verb and is assigned theta roles that would normally be assigned elsewhere in the sentence, specifically it takes the theta role of the active subject.- Toni ate the last piece of baklava.
- The last piece of baklava was eaten .
Movement in the passive
In Chomsky's generative grammar, the following example of a passive with the auxiliary be and a by phrase, gives the same reading as in an active sentence.- Zenobia idolized Caesar.
- Caesar was idolized by Zenobia.
Movement does not always take place in the passive though we see it often with by-phrases. This is because movement only takes place when a NP depends on the verb to get Case. There are instances of the passive that do not use movement.
Non-passivized verbs
Not all verbs in English can be passivized.Unaccusative verbs do not form a passive in English.
* It was wilted quickly.
- TP[VP was wilted quickly[DP it
. - [CP[TP Iti [VP was wilted quickly[DP ti
.
One argument using the lens of [cognitive grammar">TP[VP was wilted quickly[DP it
One argument using the lens of [cognitive grammar claims that this is due to how auxiliary be functions in the passive. ii With the auxiliary be, the passive needs to have a patient argument. Unergative verbs that would form an impersonal passive do not have a patient argument, so the passive can't be formed. In Dutch, the be verb functions differently, so that the agent is always present. Therefore, in Dutch, the passive doesn't require a patient argument.
Another view is that it has to do with Case. Specifically, the inability of intransitive verbs to assign Case. Since intransitive verbs do not have objects, they don't assign Case. If the verb can't assign Case, then Case cannot be obtained by the passive; so they can't be passivized. This view claims that in German and Dutch, the verbs are structural case assigners which is why they are able to passivized in those languages.
Another Case-related argument varies slightly, still agreeing that no passive can be formed since the verb has no object, meaning no case can be assigned. However, the difference in this argument is in the analysis of how the impersonal passive works in Dutch and German. In this Case-related argument, Roberts claims that German and Dutch use dative case, argued to be an inherent Case on their verbs, meaning these verbs can be put in the passive.
The reasons certain verbs cannot be passivized is not just based on syntax; there are semantic reasons behind their inability to passivize as well.
''Get'' passive
Originally the get passive was viewed as another variation of the be passive in English. It was assumed to function the exact same as the be passive, just using the verb get in place of auxiliary be. Today this is a topic of discussion among linguists who have noted that there are key differences between the behavior of a be passive and a get passive.Control and agent behavior in ''get'' passives
Some claim that the get passive is considered a subject control verb, a construction where the unstated subject is forced to refer back to the subject of the main clause by the verb.Above, PRO has to refer to Elle, making it a subject control verb. The be passive does not allow for subject control. The patient in the get passive is often seen as being to blame for the event or action occurring, more so than in the be passive. The get passive patient seems to take on more responsibility in relation to the event of the sentence.
Mary got arrested.
Mary was arrested.
In the get passive version, there is some implied amount of accountability for being arrested, as if Mary did something to cause her being arrested, making it more closely related to the event of being arrested, compared to the stative be passive which doesn't connect back to the event, but is stative. This is because in get passives there is a belief that the surface subject can be identified as a secondary agent, but this is not an available reading in the be passive.
Arguments as an adjectival passive
Some linguists argue that the get passive is actually an adjectival passive, making it not a true passive and different from be.Evidence for the get passive as an adjectival passive comes from examples where get passives are not allowed to appear and do not behave as be passives, which are demonstrated below:
Agent-Oriented Manner Adverbials
*The book got torn on purpose.
Rationale Clauses
*The ship got sunk .
Predication Structures
*The food got served .
Reflexive Pronouns
*Food should never get served only for oneself.
However, there are instances where the above examples have a get passive that is allowed in the types of constructions above, and a be passive that is not. Furthermore, get passives allow the use of the by-phrase in the same conditions as the be passive.
The criminal got arrested by Mary'.
This is something that usually isn't seen with true adjectival passives. These notions put the idea that the get'' passive may be an adjectival passive under question.
Middle voice and passival
The term middle voice is sometimes used to refer to verbs used without a passive construction, but in a meaning where the grammatical subject is understood as undergoing the action. The meaning may be reflexive:- Fred shaved, i.e. Fred shaved himself
- These cakes sell well, i.e. sell these cakes
- The clothes are soaking, i.e. is soaking the clothes
Another construction sometimes referred to as passival involves a wider class of verbs, and was used in English until the nineteenth century. Sentences having this construction feature progressive aspect and resemble the active voice, but with meaning like the passive. Examples of this would be:
- The house is building.
- The meal is eating.
- The drums are beating, i.e. the drums are being beaten
