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.
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.
