The Ancient Egyptian hieroglyphic script contains data that shed light on 3 major issues central to current metaphor studies: (a) Where is metaphor, that is, is metaphor linguistic or conceptual? (b) If metaphor is indeed conceptual, does metaphor understanding entail creation of an ad hoc category in which the vehicle is a particularly good exemplar? (c) Is metaphor processing primarily dependent on the identification and activation of the underlying "deep structure" conceptual metaphor? The script includes an elaborate system of classifiers (...) that constitute an intensely motivated, highly constrained categorization system strictly referring to conceptual, nonlinguistic configurations. The Egyptian system is a prototype-centered classification system, from which metaphor clearly emerges as a form of alternative classification. (shrink)
