Many of the vocabulary items that foreign language learners encounter involve figurative extensions of meaning. For example, "bottleneck, hard-headed" and "getting a foot in the door" all involve figurative extensions of parts of the body. To understand words and expressions such as these, language learners often need to employ figurative thinking. This book examines the nature of figurative thinking, considers its contribution to communicative language ability, and explores the implications for language teaching and learning.
