Book excerpt: This book gathers some of the latest approaches to Lexicology and Lexicography, which span from research on language for specific purposes to the study of lexical constellations and translation. It aims to present a multifaceted insight on current trends and, thus, includes papers that explore lexical processes in several areas, which comprise fields so diverse and riveting such as the language of cinema, fashion, tourism, and even comics. In addition, other papers examine the lexicon of well-established professional languages, such as the language of law, medicine and business, by revealing leading-edge perspectives on topics such as translation, word-formation, cultural clashes, or lexical selection. Key issues on learning and teaching are also considered, as part of a long tradition in the study of professional and academic languages that posits users’ learning needs as the cornerstone to the study of these languages. Therefore, this work proposes a strong emphasis on lexis and terminology, which are highlighted as the fundamental core of the definition and analysis of specialized languages. All in all, this publication intends, on the one hand, to embrace current trends in the study of specialized lexicon and terminology from the perspective of both Lexicology and Lexicography, and, on the other hand, to open new possibilities for future research.
