Negation has always been and still is a central topic in typological studies and theoretical research. Its centrality shows itself in the fact that it is not restricted to a given linguistic field but compasses the whole domain of linguistic studies. Very often, works on negation are brought about in a one-sided perspective which excludes other points of view. This book, on the contrary, puts together studies on negation based on various theoretical frameworks and aims to cover a wide range of theoretical perspectives. The book offers contributions on negation in Old Occitan, in Old Italic languages, and in several modern Romance languages (Italian, Roumanian, French, Spanish, Occitan, Catalan, among others). It covers the diachronic dimension of negation, and explores the syntactic as well as the semantico-pragmatic side of the phenomenon; aspects of negative affixation provide the morphological dimension.
