ABSTRACT
The theory of conceptual metaphors is adopted in which conceptual relations are productive of linguistic metaphorical expressions. Conceptual metaphors vary in their degree of productivity according to semantic principles. Spatial-graphical expressions of non-spatial concepts are investigated providing evidence that they are instantiations of metaphors. For three cases of differing productivity it is argued that the same semantic principles which result in metaphor productivity for linguistic expressions also result in spatial-graphical expressions. 1
