When a woman says "My husband Steve is a sheepdog," she's using a metaphor. Is she talking nonsense or saying something meaningful? Does the metaphor accomplish its intent by saying or implying something? Nogales carefully answers these questions in detail by providing an account of metaphor in terms of reconceptualization, which conforms to the intuition that metaphors inflict a change in perspectigve. At the same time, she provides an illuminating critique of accepted theories of metaphor and a list of phenomena that any theory of metaphor or natural language processing must address.
