Impersonal Structures in English: A Complete Summary
In English, we often need to express ideas without referring to a specific person or agent. We do this using impersonal structures — grammatical patterns that allow us to make general statements, report what is commonly believed, or describe situations without identifying who is responsible for an action or opinion.
Impersonal structures are especially common in formal writing, academic English, and journalism. At C1 level, you are expected to use a wide range of these structures accurately and appropriately. This lesson brings together all the key impersonal structures, explains how they work, and shows you how to avoid common errors.
Consider these two sentences:
People say that coffee is good for you.
It is said that coffee is good for you.
Both sentences report a general belief, but the second uses an impersonal structure. No specific person is named as the source of the belief. This is the core function of impersonal structures: to remove the personal subject and create a more objective, formal, or generalised tone.
Why Use Impersonal Structures?
Before exploring the forms, it is helpful to understand why native speakers and proficient writers choose impersonal structures. There are four main reasons:
- To sound formal or academic: Impersonal structures distance the writer from the claim, which is valued in academic and professional writing.
- To report beliefs without stating who holds them: Useful in journalism and when the source is unknown or unimportant.
- To describe ongoing or timeless situations: Especially with verbs like seem, appear, and tend.
- To make polite or indirect statements: Impersonal structures soften criticism and strong claims.
Type 1: It + Passive Reporting Verb + That-Clause
This is one of the most widely used impersonal structures. It allows you to report a general belief, claim, or finding without attributing it to a named individual.
Structure
It + is/was/has been + past participle + that + subject + verb
Common Verbs Used in This Structure
| Verb | Example Sentence |
|---|---|
| say | It is said that laughter is the best medicine. |
| believe | It is believed that the universe is expanding. |
| think | It was thought that the earth was flat. |
| report | It has been reported that unemployment is rising. |
| claim | It is claimed that the new drug has no side effects. |
| suggest | It was suggested that the policy had failed. |
| know | It is well known that smoking causes cancer. |
| argue | It is argued that inequality is increasing. |
| expect | It is expected that prices will rise next year. |
| assume | It was assumed that the results were accurate. |
| fear | It is feared that the species may become extinct. |
| understand | It is understood that negotiations are ongoing. |
Changing Tense in the That-Clause
The tense of the main reporting verb and the tense of the verb inside the that-clause can be varied independently to show different time relationships.
It is believed that the economy is recovering. (present belief about the present)
It is believed that the economy was recovering. (present belief about the past)
It was believed that the economy would recover. (past belief about the future)
Type 2: Subject + Passive Reporting Verb + Infinitive
This structure is an alternative to the It + passive + that pattern. Instead of beginning with it, the subject of the that-clause becomes the main subject of the sentence, followed by a passive reporting verb and an infinitive.
Structure
Subject + is/was/has been + past participle + infinitive (to + verb)
Two Infinitive Forms
The choice of infinitive depends on the time relationship between the reporting verb and the action being reported.
| Time Relationship | Infinitive Form | Example |
|---|---|---|
| Same time or future | to + base verb | The economy is believed to be recovering. |
| Earlier than the reporting verb | to have + past participle | The suspect is said to have fled the country. |
Further Examples
The president is reported to be considering his options.
The manuscript is thought to have been written in the twelfth century.
Several employees are understood to have received compensation.
The missing aircraft is feared to have crashed into the ocean.
Comparing the Two Structures
| It + passive structure | Subject + passive + infinitive |
|---|---|
| It is believed that he is innocent. | He is believed to be innocent. |
| It is said that she left early. | She is said to have left early. |
| It was thought that the plan had failed. | The plan was thought to have failed. |
| It is reported that they are negotiating. | They are reported to be negotiating. |
Type 3: It + Linking Verb + Adjective + Infinitive or That-Clause
Another important impersonal structure uses it as a dummy subject followed by a linking verb (usually be, seem, or appear), an adjective, and either an infinitive or a that-clause. This structure is very common in formal writing and for making evaluative statements.
Structure A: It + be + adjective + to-infinitive
It + is/was + adjective + to + verb
It is essential to consider all the evidence.
It was impossible to predict the outcome.
It is unreasonable to expect immediate results.
It would be wrong to dismiss these findings.
Structure B: It + be + adjective + that-clause
It + is/was + adjective + that + subject + verb
It is vital that the information be verified.
It is surprising that so few studies exist.
It is clear that further research is needed.
It was inevitable that the company would struggle.
Common Adjectives Used in This Structure
| Evaluative | Epistemic (certainty/doubt) | Emotional |
|---|---|---|
| important, essential, vital | clear, obvious, evident | surprising, shocking, remarkable |
| necessary, crucial, critical | certain, likely, unlikely | disappointing, encouraging, alarming |
| advisable, reasonable, wrong | possible, impossible, conceivable | understandable, regrettable, ironic |
Type 4: There + Be Structures
There + be is one of the most fundamental impersonal structures. It introduces a subject without making any specific person the agent, and is used to state that something exists, occurs, or is the case.
Basic Structure
There + is/are/was/were/has been/have been + noun phrase
There is little evidence to support this claim.
There were several reasons for the decline.
There has been a significant increase in demand.
There appears to be a fundamental flaw in the argument.
Advanced There + Be Patterns
At C1 level, there can combine with modal verbs and other verbs to create more nuanced impersonal structures.
| Pattern | Example |
|---|---|
| There + modal + be | There must be an explanation for this. |
| There + seems/appears + to be | There seems to be a misunderstanding. |
| There + is + no + gerund | There is no denying the scale of the problem. |
| There + is + little/no + point + in + gerund | There is little point in delaying the decision. |
Type 5: Impersonal Use of It to Describe Conditions
The pronoun it is also used impersonally to describe weather, time, distance, and general environmental conditions. In these cases, it does not refer to any specific noun — it is simply a grammatical placeholder.
Common Uses
| Category | Examples |
|---|---|
| Weather | It is raining heavily. It was bitterly cold. |
| Time | It is half past three. It was late afternoon. |
| Distance | It is only five kilometres to the nearest hospital. |
| General situation | It seems unlikely that anyone will object. |
| Cleft sentences | It was the director who made the final decision. |
It-Cleft Sentences
A particularly important impersonal use of it at C1 level is the cleft sentence, which is used to give strong emphasis to one part of the sentence.
It + be + emphasised element + relative clause
It was the lack of funding that caused the project to fail.
It is the students who ultimately benefit from this approach.
It was in 1945 that the war finally ended.
Type 6: Impersonal Structures with Seem and Appear
The verbs seem and appear are frequently used in impersonal constructions to express tentative or qualified judgements. They allow the speaker or writer to avoid making direct claims.
Four Key Patterns with Seem and Appear
| Pattern | Example |
|---|---|
| It + seems/appears + that-clause | It seems that the data was misinterpreted. |
| Subject + seems/appears + to-infinitive | The results seem to contradict the hypothesis. |
| Subject + seems/appears + to have + past participle | The witness appears to have been mistaken. |
| There + seems/appears + to be | There appears to be no simple solution. |
Type 7: Impersonal One and You
Two further impersonal subjects — one and you — are used to make general statements about people without referring to any specific individual.
Impersonal One
One is used as an impersonal subject, especially in formal or academic writing. It implies "people in general" or "a person in general".
One + verb (third person singular)
One must consider the long-term consequences.
One cannot ignore the ethical implications of this research.
One tends to underestimate the difficulty of the task.
Note: When one is used as subject, the possessive form is one's and the reflexive form is oneself.
One should always consider one's own limitations.
It is important to challenge oneself regularly.
Impersonal You
In informal and semi-formal English, you is commonly used impersonally to refer to people in general, including the speaker.
You can never be too careful with your personal data.
You tend to feel more confident with practice.
You wouldn't believe how complex the system is.
One vs You: Register Comparison
| Impersonal One (formal) | Impersonal You (informal) |
|---|---|
| One cannot predict such events. | You can't predict such events. |
| One finds such behaviour unacceptable. | You find such behaviour unacceptable. |
| One tends to overlook these details. | You tend to overlook these details. |
Type 8: Passive Constructions with Need, Require, and Want
These verbs can form impersonal structures in which the agent performing the action is omitted entirely. They are particularly useful when the focus is on what needs to be done rather than who will do it.
Patterns
Subject + need/require/want + gerund (active meaning)
Subject + need/require + to be + past participle (passive meaning)
The report needs revising before it is submitted.
The data requires careful analysis.
Several issues need to be addressed urgently.
The contract requires to be signed by both parties.
Important Differences and Special Cases
It Is vs There Is
Both it is and there is are used impersonally, but they serve different functions.
| Structure | Function | Example |
|---|---|---|
| There is/are | Introduces existence or occurrence of something | There is a growing concern about this issue. |
| It is | Evaluates, describes, or refers to a situation | It is concerning that this issue has been ignored. |
Said To Be vs Supposed To Be
These two structures look similar but carry different meanings.
It is said to be the tallest building in the world. — This is what people generally report or believe.
It is supposed to be the tallest building in the world. — This is what should be the case, or what people expect, sometimes with doubt implied.
Avoiding Ambiguity with Seem and Appear
When using seem and appear with infinitives, it is important to choose the correct infinitive form to express the correct time relationship.
She seems to be unwell. (She is unwell now — same time as the main verb.)
She seems to have been unwell. (She was unwell earlier — before the time of the main verb.)
Subjunctive After It + Be + Adjective + That
In formal British English, a subjunctive or should + infinitive form is often used after adjectives like essential, vital, necessary, important, and imperative in that-clauses.
It is essential that every participant be informed. (subjunctive)
It is vital that the report be submitted on time. (subjunctive)
It is necessary that all staff should complete the training. (should + infinitive)
Common Mistakes
❌ It is said that he escaped the country. (incorrect tense relationship — if the escape happened before the saying, a perfect form is needed in the alternative structure)
✅ He is said to have escaped the country.
❌ It seems that she left early. used when you want to show the leaving happened before the seeming
✅ She seems to have left early.
❌ One must consider their own limitations. (mixing one with their)
✅ One must consider one's own limitations.
❌ There is no point to delay the decision.
✅ There is no point in delaying the decision.
❌ It is believed the company is making a loss. (missing that — acceptable in speech but often required in formal writing)
✅ It is believed that the company is making a loss.
❌ It seems the government has taken a wrong decision. (possible but imprecise when a more formal structure is required)
✅ It appears that the government has made an error of judgement.
❌ The project needs to revise before submission.
✅ The project needs revising before submission.
❌ It is important that he completes the form today. (simple present used instead of subjunctive in formal contexts)
✅ It is important that he complete the form today. (subjunctive)
Impersonal Structures: Quick Summary
Impersonal structures are a defining feature of formal, academic, and journalistic English. Mastering them allows you to write with greater objectivity, precision, and sophistication. Here is a concise overview of the main types covered in this lesson:
| Structure Type | Pattern | Example |
|---|---|---|
| It + passive reporting verb + that | It is believed/said/reported + that... | It is believed that the situation is improving. |
| Subject + passive reporting verb + infinitive | Subject + is said/believed/thought + to (have) + verb | The economy is expected to recover. |
| It + be + adjective + to-infinitive/that | It is essential/clear/vital + to + verb / that... | It is vital that the results be verified. |
| There + be structures | There is/seems to be/must be... | There appears to be no alternative. |
| Impersonal it (weather, time, distance) | It + be + description | It is unusually warm for November. |
| It-cleft sentences | It + be + focus element + relative clause | It was the deadline that caused the most pressure. |
| Seem and appear structures | It seems/appears + that / Subject + seems + to (have) + verb | She seems to have misunderstood the question. |
| Impersonal one | One + verb; one's; oneself | One cannot underestimate the challenge. |
| Impersonal you | You + verb (general reference) | You tend to learn faster with regular practice. |
| Need/require + gerund or passive | Subject + needs + gerund / needs to be + past participle | The system requires updating immediately. |
Key points to remember:
- Use to have + past participle when the action happened before the time of the reporting verb.
- Choose between it is believed that... and subject is believed to... depending on what you wish to focus on.
- Use one's and oneself — never their or themselves — when one is the subject.
- After adjectives like essential and vital, use the subjunctive or should + infinitive in formal written English.
- Register matters: one is formal; you is informal; passive reporting structures are formal and impersonal.
Now practise impersonal structures in the exercises below.
