Book excerpt: Through the lens of cognitive science, Jokes and the Linguistic Mind investigates jokes that play on some aspect of the structure and function of language. In so doing, Debra Aarons shows that these 'linguistic jokes' can evoke our tacit knowledge of the language we use. Analyzing hilarious examples from movies, plays and books, Jokes and the Linguistic Mind demonstrates that tacit linguistic knowledge must become conscious for linguistic jokes to be understood. The book examines jokes that exploit pragmatic, semantic, morphological, phonological and semantic features of language, as well as jokes that use more than one language and jokes that are about language itself. With its use of jokes as data and its highly accessible explanations of complex linguistic concepts, this book is an engaging supplementary text for introductory courses in linguistics, psycholinguistics and cognitive science.
