No, there aren't.  You probably mean "(pure) virtual member function".
And yes, I can assure you that's the jargon that professional and aspiring
C++ developers prefer when communicating with colleagues and compilers,
certainly not wishy-washy Javaisms.

But if you squint hard enough, everything's "definition".  In fact,
definition definition definition.  Definition?  Definition!

I'm fine with that name myself, it's specifically for xref
-find-definitions, right?  I just find it nonsensical to use that
to justify the "definitions" in your proposed xref-find-all-definitions
which potentially serves to find C declarations, C++ deduction
guides, Elisp feature-providing forms, CL macroexpansion loci,
etc, etc.  I've given plenty of alternatives.
