The closest parent of the 'tag' must also have the explanation for what that word means.

The <dfn> element can be particularly useful when you want to ensure that a specific term is defined or emphasized for clarity in your content. It also provides a semantic way to mark up the term for both human readers and search engines. You can apply CSS styles to <dfn> elements to change their appearance, such as font style or color, to further emphasize the defined terms in your content.
