Text is the bread and butter of any interface, so it's essential to make it available to everyone, regardless of their disabilities or education level. Write in a manner that can be easily understood by individuals with a secondary education level. The goal is not to dumb things down but to use simple words to explain complicated concepts.

Keep your message clear and concise. Avoid long sentences. A good rule of thumb here is "one sentence, one idea." If a sentence requires a semicolon, it most likely can be split in two. Use simpler vocabulary; for example, words like "affluent" and "fortuitous" are more difficult to understand than "rich" and "lucky."

Complex content sometimes can't be simplified further. In these cases, the WCAG recommend providing additional materials that explain the same information in simpler terms. This might include summaries, glossaries, or visual explanations that complement the main content.
