Discourse Function of Inversion in English [PDF ebook] 

First published in 1997. This dissertation presents a discourse-functional account of English inversion, based on an empirical study of natural language data. The central finding is that inversion is subject to a pragmatic constraint on the information status of its constituents; specifically, the information represented by the preposed constituent must be at least as familiar within the discourse as is that represented by the postposed constituent.
