Conceptual Metaphor Theory (CMT) has been little used by archaeologists.A key barrier is that current metaphor analysis relies on linguistic evidence, a resource that archaeologists rarely have. Methods for interpreting entirely "material metaphors" have yet to develop. This article explores CMT in a domain of long-standing archaeological interest: settlement structure. Anthropologists have long recognized that hunter-gatherers place their dwellings close to those they are close to socially, usually their kin. Archaeologists have assumed the same holds true for prehistory-although without direct evidence. This article explains why people consistently associate with their kin this way, and how the metaphor, "SOCIAL DISTANCE IS PHYSICAL DISTANCE," structures hunter-gatherer campsites worldwide. Archaeologists can infer the existence of this metaphor in the archaeological record without linguistic support. Furthermore, they can assume it exists in all human societies for as long as human brains have been wired up as they currently are.Over the past thirty years, conceptual metaphor theory (CMT) has expanded from it original home in linguistics, to be used across many other human sciences and the humanities: psychology, philosophy, and literary studies have been prominent contributors (Gibbs, 2008(Gibbs, , 2011. There are disciplines, however, where CMT has seen almost no use. Among these is my own: archaeology. For archaeologists, "metaphor" is often little more than a synonym for either "symbol" or "analogy" (e.g.
