The aim of this article is to apply a long held theory of cognitive linguistics, namely the inter-dependence of meaning and form, to the study of conceptual metaphors. This has yet to be done in any rigorous manner and the current study demonstrates that it is a task well overdue. Although the investigation posits important theoretical arguments for "cognitively informed" studies of metaphor, the discussion bases its analysis in two established conceptual domains, love and anger. The discussion begins by demonstrating weaknesses in the current study of conceptual metaphors based solely on the lexicon. This is done through a brief investigation of the figurative language of anger. The investigation then moves to resolve this issue by applying the study of morpho-syntax to conceptual metaphor analysis. Through the application of formal enquiry to the analysis of the domain love, the discussion demonstrates two important points. Firstly, that morpho-syntactic study helps resolve problems of domain membership and delineation in cross-reference mapping of conceptual metaphors. Secondly, the study reveals that metaphors posses a "grammatical topology." This topology, or character, is part of the conceptual makeup of the domain that is undetectable in purely lexical analyses. [D.G.]
