Interaction of Modality and Negation [EPUB ebook] 
A Typological Study

First Published in 1997. This book is an updated version of the author’s 1994 dissertation, submitted to the Graduate School of the University of Southern California. With updated references footnotes pointing to research published after May 1994, this study of modality showcases its long history. Yet, for many centuries it seemed to be the exclusive domain of philosophers. It was not recognized by linguists as a separate object for study until comparatively recent times. The author argues that the other component of this study, negation, has fared much better.
