  Finally, these same pronouns are also sometimes used as unbound anaphors. That is, some occurrences seem not to be used demonstratively, and not to be within the scope of prior explicit quantifier phrases or other binding linguistic expressions, and yet seem to depend for their interpretation on prior occurrences of linguistic expressions. (See the entries on   anaphora and   discourse representation theory.)  For example, ‘he’ appears to be used as an unbound anaphor in discourse (7) and ‘she’ seems to be so used in (8).
