This book is a collection of selected papers dealing with the interplay between language and mind, with an emphasis on the role of the lexicon in this relationship. The lexicon is a very important part of any contemporary linguistic model nowadays, and can be studied from different perspectives. However, the focus here will be on the lexicon as an interface between mind activity and the linguistic message in terms of meaning, both denotative and connotative, because the lexicon is perhaps the most important conceptual descriptive structure that can show how mind interacts with language.
