Various terms have been introduced to characterize the distribution of reflexives and their antecedents, on the one hand, and anaphoric pronouns and their antecedents, on the other; and it is necessary to add yet another. If one examines the specific conditions under which anaphoric pronouns and reflexives are supposedly associated with their respective antecedents, one finds additional evidence indicating that anaphoric pronouns are not in complementary distribution with reflexives. Whenever the subject of the embedded phrase can be associated with a given antecedent noun phrase, the possessive determiner derived from it can also. Rather, the examples in question show a certain correspondence between reflexives and first and second person pronouns, on the one hand, and the well-formedness or ill-formedness of certain sentences in which they occupy object position, on the other. The notion same sentential ancestry captures the same facts as the notion same simplex sentence of Lees and Klima and the notion clause mates of Postal.
