Most recent work on anaphora has tended to focus on cases in which a pronoun is anaphoric on what appears to be a quantifier phrase, where it cannot be understood as a variable bound by that quantifier phrase (as it is in 5 and 6 above). Two central cases of this sort, to which attention will be confined here, are as follows.
