Explain the principle of understandability in web accessibility.

The principle of understandability in web accessibility emphasizes that content should be presented in a clear and straightforward manner. This principle ensures that all users, regardless of their cognitive abilities or disabilities, can effectively comprehend the information provided on a website. Features that support understandability include the use of plain language, logical organization of content, and the avoidance of unnecessary complexity. Such practices enhance user navigation and make it easier for individuals to parse and process information without encountering confusion.

By focusing on clarity, web content becomes more accessible to a broader audience, including those with learning disabilities, non-native language speakers, and other users who may struggle with more complex or convoluted information presentations. This principle aligns closely with the overall goal of making web content usable by everyone.
