Writing in plain language is important because:
Plain language builds a more just society
Writing plainly means more people will be able to read and understand your message.
If our audiences cannot follow legal documents, information leaflets or letters, there is the risk of their breaking the law, or failing to do what is expected of them or receiving what is rightfully theirs.” (Tasmanian Government)
Choosing not to write plainly can introduce social disadvantage. Excluding people from being able to easily understand contracts, laws and other information limits their choices. They can’t fully participate in society.
Plain language displays clear thinking
“If you can’t explain it simply, you don’t understand it well enough.” (attributed to Albert Einstein) No matter who said it, the idea is helpful.
When you have a deep understanding of an idea, you can find words, metaphors and images that help other people understand it too. You can explain the idea simply and with precision. If you only have a superficial understanding, you are likely to express the idea vaguely. It is unlikely to be written plainly.
If people understand more of what you’re saying, they will likely feel that you make sense.(Hoa Loranger)
Plain language aids effectiveness and efficiency
Business and government documents need to be both effective (achieve purpose) and efficient (read and understood quickly). Writing in plain language helps achieve both goals.
Complex, technical or pompous writing does not convey ideas quickly – readers have to battle to make sense of what is written. Writing plainly means using words and structures that your audience can quickly understand. (Knowing your audience is vital – when writing for technical readers you may use terms that lay people would call jargon.)
Writing plainly using familiar words and simple structures is not dumbing down. It helps less able readers to understand, and helps more able readers to read faster.
