The WCAG Explained

Summary:
WCAG 3.1, Readable, focuses on making web content more understandable by ensuring that the language is clear and easy to read. This principle is particularly beneficial for users with cognitive disabilities, those who are not fluent in the content's language, and users with learning disabilities.

What:
It encompasses guidelines for using clear and simple language, providing definitions for unusual words, and ensuring that content can be translated or interpreted accurately.

1. 3.1.1 Language of Page: The default language of each web page should be programmatically determined.
2. 3.1.2 Language of Parts: Any change in the language of a web page's content should be clearly identified.
3. 3.1.3 Unusual Words: Provide definitions for any unusual words or phrases used.
4. 3.1.4 Abbreviations: Define abbreviations or acronyms the first time they are used.
5. 3.1.5 Reading Level: Aim for content that is easy to read or provide simplified versions if the content requires a more advanced reading level.
6. 3.1.6 Pronunciation: When the meaning of words depends on pronunciation, provide a way to understand the pronunciation.

Why:
Clear language enhances the comprehensibility of web content, making it more accessible to a wider audience, including those with cognitive or language-related disabilities.

Examples and Scenarios:

1. Simplified Language on Educational Websites: Using straightforward language to explain complex concepts.
2. Glossaries on Technical Sites: Providing a glossary for jargon or specialized terms.
3. Translation Features on Multilingual Sites: Offering content in multiple languages or providing tools for translation.

How to Comply:

• Websites: Use plain language, provide explanations for complex terms, and offer translation options.
• Mobile Apps: Incorporate simple language and include features for understanding uncommon terms.
• Software Applications: Ensure the language used in interfaces is straightforward and easy to understand.

Exceptions:

• Specialized Content: Technical, legal, or specialized content might require specific terminology.
• Literary Use: Creative or literary works where the language is an intrinsic part of the content.
