Clear sentences in active voice improve readability. Keep sentences short to help people scan content.
Write plain language sentences
Standard English sentences are built on subject–verb–object order. This structure forms the basis of plain language writing.
Keep sentences to an average of 15 words and no more than 25 words, especially for digital content. Too many words, phrases and clauses affect people’s ability to scan sentences.
Sometimes it’s hard to avoid longer sentences – for example, if you have to include a long department name. Sentences over 25 words can usually be broken up using different techniques, like using lists.
Level AAA requires a lower secondary education reading level, after removal of proper names and titles (year 7 or between 12 and 14 years old).
Write in plain language. This helps all users and is essential for some.
WCAG quick reference: 3.1.5 Reading level – level AAA.
Use active voice
Use active rather than passive voice. Active voice helps users understand who is doing what. It can also help people know exactly what their responsibility is.
Eligible students can access the subsidy by completing the application. [Active voice]
The subsidy can be accessed by completing the application. [Passive voice]
The difference is clearest with action verbs:
- Active voice: the grammatical subject is performing the action in a sentence.
- Passive voice: the grammatical subject is undergoing the action.
Active voice: The student filed the application. [‘The student’ is the grammatical subject, who did the filing. ‘The application’ is the object.]
Passive voice: The application was filed by the student. [‘The application’ is the grammatical subject, but did not do the filing.]
Construct positive, unambiguous sentences
Words, phrases and sentences can have more than one meaning. Write exactly what you mean and construct your sentences so there is no ambiguity.
The graduate with a broken leg sat at the desk. [The graduate has a broken leg.]
The graduate sat at the desk with a broken leg. [Either the graduate or the desk could have a broken leg.]
Write sentences so they are positive rather than negative.
Include these documents when you apply.
can’t submit your application if you
don’t include these documents.
Avoid double negatives
Double negatives can lead to misunderstandings, so avoid them.
It was acceptable …
It was not unacceptable …
Eliminate unnecessary words
Make each word work for its place in the sentence. Sentence structure is clearer if each word plays a necessary role. Clear sentences improve readability.
It helps to test the combination to know which words are necessary.
Keep the words that play a critical function in the sentence. Remove all the words except the subject, verb and object (if applicable).
Check if the sentence is grammatically correct when you remove the other words.
Build the sentence back together, leaving out any words that aren’t absolutely necessary. Adverbs and adjectives are usually good to candidates to leave out in this kind of test.
Check if the basic meaning of the sentence remains, and if it’s grammatical. Then check if the words you’ve removed are really working to keep their place.

[This text uses unnecessary adverbs, adjectives and contains irrelevant information. It uses 52 words.]
Testing combinations as you write will also help create concise and easily understood headings, fragment lists and descriptive links.
Word combinations affect punctuation, spelling, capitalisation and formatting. For example, there are rules about the use of commas between adjectives and the use of hyphens between adverbs and verbs.
Avoid unnecessary words. Keep the words needed to make meaning clear.
Call us if you have any questions.

Avoid using ‘there is’ and ‘there are’ when they only add extra words and not meaning.

Vary sentence structure
Vary your sentence structure to suit the content.
Simple sentence structures are easier to scan. People understand meaning through the order of words in a sentence. A simple sentence construction has fewer parts to take in.
Compound and complex sentences can add variety and flow to your writing. Sentences should still be easy to scan, even using these structures.
Complex structure is harder to follow, regardless of a person’s literacy level. Complex structures take more effort to read, even if they are punctuated properly.
You can delete your application
within an hour of applying.
[‘Within an hour of applying’ modifies the main clause.]
within an hour of applying, delete your application.
[The modifier is inserted into the main clause. This structure is complex and slows down reading.]
Build simple phrases and clauses
Phrases and clauses are groups of words that work as nouns, verbs, adjectives, adverbs or prepositions in sentences.
You can build layers of meaning by combining different types of words, phrases and clauses. Layering sentences makes them more complex.
The plane arrived.
The plane arrived
The plane arrived in Darwin
The plane arrived in Darwin carrying freight
that needs inspection.
The plane arrived in Darwin carrying freight that needs inspection
for dangerous goods.
The plane arrived in Darwin carrying freight that
– before being unloaded – needs inspection for dangerous goods.
Some common constructions used in bureaucratic writing are complex and unnecessary. They add words but not meaning.
Instead of bureaucratic language, use plain language words and terms.
For example, use a verb instead of the noun that relates to the verb. If you use the noun instead, you have to change the verb into the noun and usually add other words.
Please apply. [‘Apply’ is the verb.]
Please make an application. [‘Application’ is the noun that relates to the verb ‘apply’.]
Use fewer than 3 adjectives or nouns at a time
Phrases that combine more than 3 adjectives or nouns are difficult to understand. Rephrase sentences to break up strings of adjectives or noun trains.
You can often rephrase the string of adjectives or noun train as a clause. Follow the rule to keep sentences short and their structure simple.
The goal is to analyse how we can reallocate human resources. The analysis will inform our business plan.
human resource reallocation analysis will inform our business plan.
[‘Human resource reallocation analysis’ is a noun train that is difficult to understand.]
Avoid using ‘if’ and ‘unless’ together
Don’t use words such as ‘if’ and ‘unless’ in the same sentence.
From 1 October, your partner can sign forms on your behalf.
If your partner signed the form on your behalf, we can accept it
unless they signed it before 1 October.
Use ‘other than’ carefully
When you use ‘other than’, make sure it’s clear which words are included in the exception.
A person who is younger than 60, other than a teacher ...
A person other than a teacher who is younger than 60 ...
Avoid ‘such ... as’ and ‘being’
Don’t use the ‘such ... as’ form.
Take appropriate steps.
such steps as are appropriate.
Use ‘and’ instead of ‘being’ or ‘not being’.
A person who is 70 or over
and has a driving licence ...
A person who is 70 or over,
being a person who has a driving licence ...
The digital edition has practical guidance on plain language:
- It discusses plain language sentences and relates grammatical concepts to the principles of plain language.
- It consolidates information from the sixth edition and highlights the basics about clauses. It takes a different approach to the sixth edition by breaking grammar topics into specific subject areas like ‘phrases’ and ‘types of words’.
- It provides an overview on types of words to introduce grammatical concepts about parts of speech and how they relate to sentence structure.
The sixth edition called types of words ‘word classes’. It had summary information about parts of speech on pages 68 to 70. This formed part of Chapter 5 on grammar.
The sixth edition and Content Guide referred to ‘plain English’ only. The digital edition relates plain language to writing in the English language.
The Content Guide did not have any in-depth information on grammatical concepts.
