This is not really different from "clickable text".
Clickability is a presentational/behavioral property specific to
interactive visual media with a pointing device, but the semantics of
clickable-something is usually "hyperlink" (though sometimes e.g.
"button"). To express hyperlink semantics, we have <a>.
> glossary links: <abbr title="hypertext markup language"
For <abbr>, it's probably worth adding the href attribute if the use case
is frequent. The rationale would be that the semantic unit delimited by
<abbr> can be said to have such property as the reference URL to look up

Most cases when there are nested <a> and some other element which cover
exactly the same range (<a><other>...</other></a> or
<other><a>...</a></other>) don't deserve merging of <a> and <other>
because it just happens sometimes that the elements cover the same range,
but it could be different. For example, an <a> could cover only part of a
<li> in your example above, or <a> in a gallery item could include both a
thumbnail and a caption below that.

"Clickability" is presentational/behavioral. "Destination URI" has
different semantic meaning when applied to different elements, and no
meaning at all when applied to some (e.g. <input>).
