Los relacionantes locativos en la historia del español [PDF ebook] 

There is no survey study to date that would have analyzed the history of spatial relations in Castilian Spanish, i.e. the prepositions, transitive adverbs as well as prepositional and adverbial locutions used for the spatial localization of entities. Based on an extensive corpus, this book offers a complete diasystematic characterization of these aspects and discusses new hypotheses with regard to their correlations.
