Plain language

Plain language is writing designed to ensure the reader understands as quickly, easily, and completely as possible. Plain language strives to be easy to read, understand, and use. It avoids verbose, convoluted language and jargon. In many countries, laws mandate that public agencies use plain language to increase access to programs and services. The United Nations Convention on the Rights of Persons with Disabilities includes plain language as one of the "modes, means and formats of communication."

Most literacy and communications scholars agree that plain language means:

Plain language focuses on ways of writing a text so that it is clear, concise, pertinent, efficient, and flows well for the reader. The Center for plain language states that: “[a] document, web site or other information is in plain language if the target audience can read it, understand what they read, and confidently act on it.” Writing in plain language does not mean oversimplifying the concepts, but presenting the information in a way that makes it easier to understand and use by a wider audience. Texts written in plain language are still formal, but are easier to read and inspire confidence for the reader.

Using plain language in communications ultimately improves efficiency, because there is less ambiguity for the readers, and less time is taken for clarifications and explanations. Clear communication improves the user’s experience with the organization, ultimately creating trust in the company.

Writers who wish to write in plain language must first and foremost consider their target audience. This should have an influence on what information is included in the text and on how it is written. Different audiences have different needs, and require different information. When writing, it is important to consider what the target audience needs to accomplish, and what and how much information they need to complete it. The target audience will also affect the chosen vocabulary: writing for someone in the same field as the author is different than writing for someone for whom English is his or her second language.

The text must be organized logically: the most important information should be mentioned first, in the text as a whole and in every individual paragraph. Headings help the reader skim the text more rapidly to find what he or she is looking for. Sentences should be kept short, and only include the necessary information. A long, verbose sentence tends to present too much information at once, and blurs its main point. The text should be direct and concise, and have an easy flow to it.
