Subshells aside, I have a hard time believing that "the process ID
of the shell" confuses anybody in practice.  Even POSIX doesn't
overcomplicate this:

    $
        Expands to the decimal process ID of the invoked shell.  In
        a subshell (see Shell Execution Environment), '$' shall
        expand to the same value as that of the current shell.
