Plain English

Make content clear and understandable, to open the web up for users with different literacy levels and access challenges.

WCAG states that "using the clearest and simplest language appropriate is highly desirable."

The United Nations recommends plain language for communications.

1. Choose easy and short words not formal, long ones.

Use ‘buy’ instead of ‘purchase’, ‘help’ instead of ‘assist’, and ‘about’ instead of ‘approximately’.

Write for the reading comprehension of a 9 year old. This helps you reach the most users and makes your content easy to scan.

2. Jargon and buzzwords are unlikely to be clear language.

Often, these words are too general and vague and can lead to misinterpretation or empty, meaningless text. Avoid them. Instead, think about what the term actually means and describe that. Be open and specific.

Example:
"Let's touch base in 10 and do some blue sky thinking." This uses jargon.
"Let's meet in 10 minutes to think of some ideas." Conveys same meaning using clear language.

3. Write conversationally.

Picture your audience and write as if you were talking directly to them, with the authority of someone who can help and inform.

4. Test your content with users

What is 'plain' for one person may not be for someone else.

Simple sentences

1. Make your average sentence 15 words long.

The maximum sentence length for a good level of comprehension is 25 words. Split long sentences up into 2 or 3, or use bullet points.

Oxford Guide to plain English, GOV.UK and linguists agree 15 word sentences are fine but above 40 words is hard to understand.

2. Avoid complex sentence structures.

They are less easy to comprehend quickly. Understanding them requires more cognitive effort than simple sentences.

Complexity depends on:

number of clauses in a sentence, the more clauses the more complex it is
distribution of associated words across the sentence – how easily can the brain 'parse a phrase': recognise, connect and comprehend words that together convey meaning

Example:"The red fox jumped over the gate." – easier to understand
"The fox, which was red, over the gate jumped." – harder to understand

Specialist terms

Make specialist content comprehensible by non-experts.

1. Explain specialist terms: anybody can access your content.

Assuming who your audience is, and that they'll understand the technical terms you use, are common misconceptions.

2. Create content that all users can understand, whatever their expertise or background.

When you present a concept explain its parts and processes in detail.

If you need to include a technical term consider explaining it. Make sure the surrounding language in plain language.

3. Help users understand specialist terms.

You could:

link to an existing definition – this could be an external site
add a explanatory definition after using the term

Example:

"It is a Palladian style stone building, and contains a number of splendid paintings and much fine wood-carving." – original sentence (source yourdictionary.com).

"It is a Palladian style stone building, and contains a number of splendid paintings and much fine wood-carving." – with link to a definition.

"It is a Palladian style stone building and contains a number of splendid paintings and much fine wood-carving. Palladian style architecture features include columns, symmetry and decorative arches." – with explanatory definition.
