Writing in Plain Language

Pencil with alphabet

To write in plain language means to use the simplest, most straightforward way of expressing an idea. Doing so will ensure your audience understands it the first time they read or hear it. Materials are in plain language if your audience can:

  • Find what they are looking for
  • Understand what they find the first time they read or hear it
  • Use what they find to meet their needs

The following are resources and tools that can help you develop or assess patient materials so that they adhere to plain language principles.
