The Lexicon provides an introduction to the study of words, their main properties, and how we use them to create meaning. It offers a detailed description of the organizing principles of the lexicon, and of the categories used to classify a wide range of lexical phenomena, including polysemy, meaning variation in composition, and the interplay with ontology, syntax, and pragmatics. Elisabetta Jezek uses empirical data from digitalized corpora and speakers' judgements, combined with the formalisms developed in the field of general and theoretical linguistics, to propose representations for each of these phenomena. The key feature of the book is that it merges theoretical accounts with lexicographic approaches and computational insights. Its clear structure and accessible approach make The Lexicon an ideal textbook for all students of linguisticsatheoretical, applied, and computationalaand a valuable resource for scholars and students of language in the fields of cognitive science and philosophy.
