When you sit down to write an IELTS Task 2 essay or a PTE Write Essay response, the examiner is looking for consistent use of formal academic register. Register means the level of formality in your language — and in academic writing, this involves making specific grammatical choices that signal objectivity, precision, and authority.
Formal academic writing has several distinctive features. First, it favours impersonal constructions. Instead of writing 'I think pollution is a serious problem,' you would write 'It is widely acknowledged that pollution poses a serious threat.' The impersonal passive 'It is widely acknowledged' removes your personal opinion and presents the claim as a consensus view. This is not about hiding your opinion — it is about presenting it with academic weight.
Second, formal writing relies on nominalization, which you practised in Unit 2. Rather than 'The government decided to invest,' you write 'The government's decision to invest compressed information into a denser, more academic form. Nominalization is one of the clearest register markers an examiner will notice.
Third, formal prose uses hedged language. Claims like 'Technology destroys jobs' sound blunt and unsupported. A formal alternative would be 'Technology may lead to significant reductions in employment in certain sectors.' The hedging modals and phrases from Unit 3 are essential tools here.
Fourth, formal writing avoids contractions (do not instead of don't), colloquial vocabulary (a considerable number instead of a lot of), and phrasal verbs where single-word equivalents exist (increase instead of go up, discover instead of find out, establish instead of set up).
These features work together as a system. A single informal expression in an otherwise formal paragraph can undermine your score because examiners assess consistency. The goal is not to make every sentence maximally complex — it is to maintain a steady, appropriate level of formality from your first sentence to your last.
It is often argued that governments bear primary responsibility for addressing climate change. The implementation of stricter emissions regulations has been proposed as a viable solution, although the economic implications of such measures remain a subject of considerable debate.
This passage demonstrates consistent formal register through several features working in combination. The impersonal passive 'It is often argued' avoids attributing the claim to a specific person, presenting it instead as a widely held view. The nominalization 'The implementation of stricter emissions regulations' compresses what could be a full clause ('if governments implement stricter regulations') into a dense noun phrase. The hedged phrase 'has been proposed as a viable solution' avoids categorical certainty, and 'remain a subject of considerable debate' maintains academic caution. There are no contractions, colloquialisms, or personal pronouns — the entire passage reads as objective analysis.
The allocation of public funding to scientific research is widely regarded as a catalyst for economic development. Numerous studies have demonstrated that increased investment in research and development correlates strongly with long-term productivity gains.
Notice how the nominalized subject 'The allocation of public funding' performs the work of an entire clause about how public funding is allocated. The passive construction 'is widely regarded' presents the claim as academic consensus rather than personal opinion. The verb 'correlates strongly with' is precise and cautious — a less experienced writer might use 'leads to,' but the formal choice avoids overstating a causal relationship. 'Numerous studies have demonstrated' adds evidential weight without citing a specific source, which is common in exam writing where you cannot reference real studies.
While some commentators maintain that technological unemployment is inevitable, others contend that innovation consistently generates new categories of employment. The relationship between automation and labour markets is therefore considerably more nuanced than popular discourse would suggest.
This passage models balanced academic argumentation. 'Some commentators maintain' and 'others contend' attribute views without resorting to the informal 'people think' or 'some people say.' The hedged structure 'is considerably more nuanced than...would suggest' avoids a direct statement of fact, instead presenting the complexity of the issue as the key point. The logical connector 'therefore' links evidence to conclusion, and 'popular discourse' replaces the informal 'what ordinary people believe.' The overall effect is measured, authoritative, and appropriately cautious.
(Academic writing should use impersonal constructions rather than direct personal statements. Replace 'I strongly believe' with an impersonal passive or a hedged attribution to maintain formal register.)
(Replace phrasal verbs with formal single-word equivalents (found out → discovered) and replace colloquial intensifiers and quantifiers with formal alternatives (really → highly, a lot of → a considerable number of).)
(Avoid contractions in formal writing (shouldn't → cannot, it's → it is). Replace informal intensifiers (huge → significant) and use formal subordinating connectors (because → as). 'Getting worse every year' can be condensed to 'escalating' for greater formality.)

Semi-Formal and Informal Register
4 exercises · 25 min
Key structures
Semi-formal: I am writing to inquire about..., I would be grateful if...
Informal: I wanted to tell you..., Hope you're doing well..., Can you...?
Not every exam task requires formal academic register. IELTS General Training Task 1 asks you to write letters, and the register depends on who you are writing to. If you are writing to a landlord, employer, or institution, the register is semi-formal. If you are writing to a friend, it is informal. Using the wrong register will cost you marks in Task Achievement, even if your grammar is otherwise accurate.
Semi-formal register sits between academic formality and conversational ease. You still use complete sentences and polite constructions, but you may use 'I' and 'you' because you are addressing a specific person. Key grammatical features include: polite modals ('I would appreciate it if you could...'), indirect requests ('I was wondering whether it would be possible to...'), and formal openers ('I am writing to inquire about...'). You avoid contractions in semi-formal letters, but the tone is warmer and more personal than an essay.
Informal register, used for letters to friends, allows — and even encourages — features that would be errors in academic writing. Contractions are expected (I'm, don't, we've). Phrasal verbs are natural (catch up, look forward to, get in touch). Personal pronouns dominate (I, you, we). Sentence fragments are acceptable (Hope you're doing well! Sounds great!). Colloquial vocabulary is appropriate (stuff, loads of, pretty good).
The critical skill is instant recognition. When you read the task prompt, your first decision must be: who am I writing to? A friend? Use informal register. A landlord, manager, or official? Use semi-formal. An academic question? Use formal register. This decision should happen in the first fifteen seconds and should never change during your response. Mixing registers — starting a letter to a friend with 'I am writing to enquire about your recent relocation' — is a serious error that signals the examiner you cannot modulate your language.
I am writing to express my concern regarding the noise levels in the apartment building where I currently reside. Over the past several weeks, the disruption caused by late-night construction work has made it extremely difficult to sleep. I would be most grateful if you could look into this matter and inform me of any steps that are being taken to address it.
This is a textbook semi-formal letter. The opener 'I am writing to express my concern' is a standard semi-formal formula. 'I would be most grateful if you could' is an indirect, polite request — a direct command like 'Please stop the noise' would be too blunt. 'Regarding,' 'reside,' and 'address' are formal vocabulary choices, but the use of 'I' and 'my' signals that this is personal correspondence, not an academic essay. The overall tone is respectful and measured without being cold or impersonal.
I am writing to let you know that I have decided to resign from my position as Marketing Assistant, effective from 30th November. I have thoroughly enjoyed my time at the company and am grateful for the opportunities I have been given. I would appreciate it if you could confirm the final arrangements regarding my outstanding annual leave.
This semi-formal resignation letter balances professionalism with personal warmth. 'I am writing to let you know' is slightly less formal than 'I am writing to inform you,' appropriate for a letter to a direct manager. 'I would appreciate it if you could confirm' is the polite indirect request typical of semi-formal register. The sentence 'I have thoroughly enjoyed my time' adds a personal note without becoming overly casual. Notice that contractions are avoided — even though this is personal, the context (resignation) demands a degree of formality.
Hey Sarah, Just wanted to let you know that I've finally moved into the new flat! It's pretty small but I love it. The area's really nice and there are loads of cafés nearby. You should come and visit sometime — we could catch up over coffee. Hope you're doing well! Give me a shout when you're free.
This informal letter uses features that would be errors in any other register: contractions throughout (I've, it's, you're, we've implied), phrasal verbs (moved into, catch up, give me a shout), colloquial intensifiers (really nice, pretty small, loads of), sentence fragments (Hope you're doing well!), and direct personal address (Hey Sarah). The exclamation marks and casual sentence rhythm create a warm, conversational tone appropriate for writing to a friend. None of these features are mistakes here — they are the correct register choices for this context.
(This is a letter to a friend, so semi-formal register is inappropriate. The language should be casual, direct, and warm. 'I am writing to enquire' and 'at your earliest convenience' are formulas for formal or semi-formal letters, not personal correspondence.)
(A letter to a landlord or property manager requires semi-formal register. Contractions (it's), colloquial phrases (freezing, ASAP), and informal closings (Cheers) are inappropriate. Use polite indirect requests and formal vocabulary.)
(Even though this is a workplace email to a colleague, the formality level should be semi-formal when addressing someone by title. Contractions (I'm, you've) and phrasal verbs (get in touch) should be replaced with their formal equivalents to maintain consistent semi-formal register.)

Key structures
Formal markers: impersonal constructions, passive voice, nominalizations, hedging
Informal markers: contractions, phrasal verbs, personal pronouns, direct address
By this point in the course, you understand what formal, semi-formal, and informal register look like individually. The real challenge — and the skill that will protect your score in the exam — is maintaining consistent register throughout an entire response. Inconsistent register is one of the most common reasons students underperform in Grammatical Range and Accuracy, because a single informal slip in a formal essay is immediately noticeable.
Register inconsistency typically takes three forms. The first is the 'opening slip': a student writes a strong formal paragraph but starts with 'I reckon' or 'I think that.' The second is the 'mid-paragraph intrusion': an otherwise formal text suddenly includes a phrasal verb ('the government set up new rules'), a contraction ('it's clear that'), or an informal intensifier ('a really big problem'). The third is the 'conclusion collapse': the student runs out of time and reverts to simpler, more casual language in the final sentence.
To diagnose register problems, you need to develop a mental checklist of formal markers and informal markers. Formal markers include: impersonal passives, nominalizations, hedged modals, formal connectors (furthermore, nevertheless, consequently), and formal vocabulary. Informal markers include: contractions, personal pronouns (especially 'I' and 'you'), phrasal verbs, colloquial vocabulary (stuff, things, a lot of), direct questions, and exclamation marks.
The self-editing process is straightforward. After writing, scan your text from beginning to end. For each sentence, ask: 'Does this sentence contain any informal markers?' If it does, replace them. Then scan again for formal markers: does every paragraph contain at least one impersonal construction or nominalization? If not, consider adding one. This two-pass approach takes only two to three minutes but can significantly improve your consistency score.
I think that the environment is a really important issue and the government should do more about it. It is widely acknowledged that industrial emissions constitute a primary driver of atmospheric pollution. Moreover, the implementation of renewable energy policies has been shown to mitigate carbon output significantly. But at the end of the day, people need to change their behaviour too.
This paragraph demonstrates a classic register inconsistency problem. The first sentence uses personal opinion ('I think'), an informal intensifier ('really important'), and a vague expression ('do more about it'). The second and third sentences shift abruptly to formal register with impersonal passives ('It is widely acknowledged'), nominalization ('the implementation of'), and formal connectors ('Moreover'). The final sentence collapses back into informality with the colloquial phrase 'at the end of the day' and the vague 'people need to change.' An examiner would note three distinct register levels within a single paragraph, which undermines Grammatical Range and Coherence scores.
It is widely acknowledged that the environment represents one of the most pressing challenges facing contemporary society. The accumulation of industrial emissions constitutes a primary driver of atmospheric pollution, and the implementation of renewable energy policies has been shown to mitigate carbon output considerably. Nevertheless, meaningful progress also requires a shift in individual behaviour, as systemic change alone may prove insufficient to address the scale of the crisis.
This revised version achieves consistent formal register throughout. 'It is widely acknowledged' replaces 'I think.' 'One of the most pressing challenges facing contemporary society' replaces 'a really important issue.' The nominalization 'the accumulation of industrial emissions' and the formal verb 'constitutes' replace the informal causal link. 'At the end of the day, people need to change' becomes the hedged 'meaningful progress also requires a shift in individual behaviour, as systemic change alone may prove insufficient.' Every sentence uses at least one formal marker, and no informal markers appear anywhere.
(The phrasal verb 'sort out' and the contraction 'it's' break the formal register established in the first sentence. Replace 'sort out' with 'address' and expand the contraction. 'Getting worse every year' is replaced with the more formal 'continues to deteriorate.')
(Multiple informal markers intrude: 'a lot of' (→ numerous), 'helps countries grow' (→ facilitates economic growth), 'people can get access to' (→ broadens consumer access), 'some people reckon' (→ others contend), 'big problems' (→ significant threats). Each informal expression pulls the register downward and creates inconsistency with the formal opening.)
(The contraction 'It's' and the conversational interjection 'honestly' are informal markers that clash with the formal opening. 'Something that affects everyone' is vague and casual — 'its effects are far-reaching' is precise and formal. 'Not enough is being done about it' becomes 'the global response has thus far been insufficient.')
Exercises
I reckon that technology has totally changed the way we learn. It's now possible for students to access loads of information online, which is pretty amazing. However, some people say that too much screen time is bad for kids. Studies have shown that it can lead to problems with concentration and sleep. At the end of the day, I think schools need to find a balance between using technology and making sure students don't overdo it.
Some people think that the best way to reduce crime is to give longer prison sentences. Others believe there are better alternative methods of reducing crime. Discuss both views and give your opinion.
