Ensure that there is a way to identify specific definition words such as jargon and idiom.

Official Requirements

Success Criterion 3.1.3 Unusual Words (Level AAA): A mechanism is available for identifying specific definitions of words or phrases used in an unusual or restricted way, including idioms and jargon.

Why is it required?

People with cognitive, learning and language disabilities may find it difficult to decode complex words, phrases, and understand the context. Therefore, providing a way to identify definitions of such words will help these users easily consume content. 

How do we fix it?

  • Provide a description list in alphabetical within the same page or link it to a separate glossary page
  • Provide a mechanism to access an online dictionary to the web page
  • Ensure that the words having different meanings on the same page are also defined
