First, URs [untriggered reflexives] that are unacceptable as single NPs gain acceptability in coordi­nate NPs, as illustrated by sentences like: *Myself/several of the employees and the myself wrote to the chairman. This phenomenon is explained if we assume that NP node dominating a coordinate NP serves as a barrier to government, thereby blocking normal rules of case assignment. Thus, where we would expect to find, say, only objective case (e.g., me), we find both nominative and reflexive forms as well (e.g., I and myself). In such constructions, DRs seem to be alternative forms of personal pronouns rather than true anaphors.

Second, URs that are unacceptable in single NPs become acceptable in postgeneric NPs, as exemplified by There are groups for ?yourself/people like yourself: This phenomenon is explained if we assume that a single reflexive subject has no c-commanding argument and thus cannot be properly bound. On the other hand, the object of a postgeneric PP does have a c-commanding argument and CAN be properly bound. In such constructions, reflexives are not actually “untriggered” at all, but, rather, have the properties of true ana­phors.

Third, URs can supplant the corresponding personal pronouns even outside of coordinate structures and postgeneric PPs, as shown by sentences like: This is a photograph of me/myself. This phenomenon reflects the different discourse functions of personal and reflexive pronouns: personal pronouns have an exophoric function and identify a discourse participant, while reflexive pronouns have an anaphoric function and identify a discourse referent.

Finally, first and second person URs are relatively more acceptable than third person URs, as exemplified by sentences like: This is a photograph of myself/yourself/?himself. These judgments are explained once we recognize that only first and second person pronouns can refer to discourse partici­pants. Thus, the distinction between third person personal pronouns and URs serves no discourse function, since third person pronouns necessarily identify a discourse referent.

” Usages such as Jane and myself went to the cinema and They saw John and myself in the street are on the increase – an ancient usage, which remained alive only in a few regional varieties, notably Irish English, but which is widespread in British English now. (And outside of Britain? Comments, please.) So expect to see more examples of this in the next generation of book and film titles. We’ve already had Oscar Wilde and Myself, My Father and Myself, and a few others. If they ever remake the cult film, and feel the need to retitle, it could be Withnail and Myself. >”
