This article aims to illustrate the role that conceptual metaphor plays in the complex dynamics of interpersonal communication, with the focus being placed upon the synergistic relationship that metaphor holds with other Idealized Cognitive Models (Lakoff, 1987) in the construction of illocutionary meaning. This goal is pursued under the scope of the Cost-Benefit Cognitive Model(Baicchi & Ruiz de Mendoza, 2010), which has been elaborated to overcome the shortcomings of traditional relevance-theoretic approaches and to ground illocutionary activity within the constructionist strand of Cognitive Linguistics. The qualitative analysis of Webcorp data retrieved for the suggesting high-level situational cognitive model offers an exemplification of the interplay that metaphor holds with frames, image schemas, and metonymy.
