HTML Element <dfn>

HTML is getting more and more semantic it seems. I am seriously wondering what this means for building things like a blog, like this one here. It becomes more and more reasonable to write pure HTML, instead of markdown, doesn't it? Maybe I am just late and just learned about some HTML elements now. What a shame.

On MDN it is described like this:

The HTML Definition element (<dfn>) is used to indicate the term being defined within the context of a definition phrase or sentence.

The example code shown there is:

<p>
  A <dfn>validator</dfn> 
  is a program that checks for syntax errors in code or documents.
</p>

Which renders like you see below:

A validator is a program that checks for syntax errors in code or documents.

If you are curious and want to get a (quick) overview of all HTML elements and where and how to use them, the "HTML elements reference" on MDN is a great place to start reading and dive deeper. It has sections such as "Document metadata", "Content sectioning" and "Text content", to name a few interesting ones.
