Key takeaways
- Plain English means the reader understands your message the first time. It is measured by the reader’s comprehension, not by the writer’s satisfaction.
- It is not simplification. Complex ideas can be expressed plainly without losing precision or authority.
- Australian literacy data suggests a large share of adults find dense text hard work, which makes clarity a practical matter rather than a stylistic preference.
- In several Australian contexts plain language is effectively a regulatory expectation, not a nicety.
- The techniques are learnable: shorter sentences, active voice, familiar words, one idea per paragraph and a structure that answers the reader’s question first.
Plain English is a style of writing that lets readers find what they need, understand it the first time and act on it without rereading. It favours familiar words, short sentences, active voice and a structure built around the reader’s question rather than the writer’s process. It is a discipline of clarity, not simplification.
What is plain English?
Plain English is defined by the effect it has on the reader rather than by a list of rules, which is the point most style debates miss. A document is written in plain English if its intended audience can find what they need, understand it on a first reading and use it with confidence. The Australian Government Style Manual builds its guidance on exactly this basis, recommending short and simple sentences in active voice, everyday words in place of long ones and the removal of jargon unless the audience is certain to understand it. Notably, the Style Manual now uses the broader term plain language rather than plain English, because the principles apply to communication generally. The test remains the same either way: did the reader get it.
What plain English is not?
The most persistent objection to plain English is that it dumbs writing down, and the Australian guidance rejects that framing directly. The Government writing handbook, published alongside the Style Manual, makes the point that using plain language is not dumbing your writing down but opening it up, and that it reduces cognitive load for every reader, including highly literate people who are short of time and have a great deal to read. That last group is worth pausing on. Executives, clinicians, engineers and lawyers are not helped by dense prose. They are simply better equipped to survive it. Plain English also does not mean short documents, banned technical terms or a casual tone. A technical term is fine when the audience shares it and it is defined when they do not.
Why does plain English matter in Australian workplaces?
Clarity has a measurable audience problem in Australia, which moves the case for plain English from preference to practicality. The most recent national assessment published by the Australian Bureau of Statistics (ABS), drawn from the Programme for the International Assessment of Adult Competencies, found that around 44 per cent of Australian men and 45 per cent of Australian women had literacy skills at Level 2 or below, meaning they can handle straightforward text but struggle when a document requires inference or the combining of several pieces of information. The data is now dated and the ABS has no further release planned, but the direction is clear enough to act on. If close to half your audience finds dense text genuinely hard work, a policy written for the writer rather than the reader is not a neutral choice. It is a decision to be misunderstood.
The organisational cost shows up as rework: repeated questions, missed deadlines, incorrect form submissions and complaints that trace back to a sentence nobody could parse.
Where is plain English expected in Australia?
Plain language has moved from good practice to expressed expectation in several Australian settings, which raises the stakes for organisations that treat it as optional. Australian Government content is written to the Style Manual as the standard for all government information. In corporate disclosure, section 715A of the Corporations Act 2001 requires a prospectus to be worded and presented in a clear, concise and effective manner, and the Australian Securities and Investments Commission (ASIC) explains what that means in practice in Regulatory Guide 228 Prospectuses: Effective disclosure for retail investors, which advises issuers to avoid double negatives, prefer verbs over nouns, resist defining commonly understood terms and use layout and white space to help readers navigate. Read side by side, the government and corporate guidance describe the same craft. One calls it plain language and the other calls it clear, concise and effective disclosure.
How do you write in plain English?
The techniques are specific and learnable, which is encouraging news for anyone who has been told their writing is unclear without being told what to change. Lead with the answer rather than the background, because most readers want the conclusion before the reasoning. Keep sentences to a single idea and aim for an average around 15 to 20 words. Use active voice so the reader can see who does what, since a sentence like the reform was implemented hides the person responsible. Choose the shorter word when it carries the same meaning, so utilise becomes use and in the event that becomes if. Replace nominalisations with the verbs they came from, turning the provision of assistance into helping. Use headings and lists as signposts, and define a technical term the first time it appears if there is any doubt.
None of these techniques requires you to abandon precision. Most of them increase it, because vague writing usually hides vague thinking.
How do you know your writing is clear?
The only reliable test of plain English is another person, which is why readability scores should be treated as a rough signal rather than a verdict. Give the draft to someone in the intended audience, ask them what they think it is asking them to do and watch where they hesitate or reread. Automated readability measures can flag long sentences and unfamiliar words, but they cannot tell whether the structure matches the reader’s question or whether the key message is buried on page three. Testing with real readers takes a fraction of the time that answering their confused emails will.
If you want to build this deliberately, our program on plain English writing with clarity and confidence works through these techniques on documents people actually produce at work, which tends to be more useful than a style guide alone. It is a practical starting point if your team writes reports, briefs, policies or client communication and wants that writing to land the first time. AcademyGlobal (AG) delivers it alongside its wider leadership and management and negotiation, influence and persuasion streams, where clear written communication does much of the quiet work behind influence.
Plain English is a professional skill rather than a stylistic taste. It respects the reader’s time, reduces the cost of being misunderstood and, in a growing number of Australian contexts, meets an expectation that regulators and standards bodies have now written down. Writing that is hard to read is rarely a sign of sophistication. More often it is a sign that the thinking has not finished yet.
Frequently asked questions
What does plain English actually mean?
It means writing that the intended audience can find, understand on a first reading and act on with confidence. The measure is comprehension by the reader rather than adherence to a fixed set of rules, so the same content might be written differently for two different audiences.
Is plain English the same as plain language?
They describe the same approach. Plain language is now the preferred term, including in the Australian Government Style Manual, because the principles apply across languages and formats rather than only to written English.
Does plain English mean avoiding technical terms?
No. It means using technical terms only where the audience shares them, and defining them clearly the first time when they do not. Removing necessary precision would make writing less useful, which is the opposite of the intent.
What sentence length should I aim for?
An average of roughly 15 to 20 words per sentence works well for most workplace writing. Averages matter more than individual sentences, since varied length keeps prose readable while the average keeps it manageable.
Is plain English required by law in Australia?
In some contexts, effectively yes. Section 715A of the Corporations Act 2001 requires prospectuses to be clear, concise and effective, and ASIC Regulatory Guide 228 explains how. Australian Government content is written to the Style Manual, and many agencies apply plain language requirements to public facing material.
