An Introduction to Lexical Semantics provides a comprehensive theoretical overview of lexical semantics, analysing the major lexical categories in English: verbs, nouns, adjectives, adverbs, and prepositions. The book illustrates step-by-step how to use formal semantic tools. Divided into four parts, covering the key aspect of lexical semantics, this book: - introduces readers to the major influential theories including the syntax-lexical semantics interface theory by Levin and Rappaport and Pinker, the generative lexicon theory by Pustejovsky, and formal semantic analyses - discusses key topics in formal semantics including metonymy, metaphor, and polysemy - illustrates how to study word meaning scientifically by discussing mathematical notions applied to compositional semantics Including reflection questions, summaries, further reading, and practice exercises for each chapter, this accessible guide to lexical semantics is essential reading for advanced students and teachers of formal semantics.
