This article proposes to apply Steen’s (2008) three-dimensional model of metaphor analysis in communication to a corpus of political discourse, in this case citizen discourse. Our corpus has accordingly been analysed by making a distinction between three layers of metaphor, respectively at the linguistic (direct vs. indirect metaphors), conceptual (novel vs. conventional metaphors) and communicative levels (deliberate vs. non-deliberate metaphors). Our results suggest that making the distinction between deliberate and non-deliberate metaphors leads to meaningful political insights, notably pointing to differences in saliency of the source domains in terms of which citizens make sense of Belgian federalism. In this regard, the family domain, and more especially the metaphor BELGIAN FEDERALISM IS A LOVE RELATIONSHIP appears to function as an important conceptual reference point for the citizens’ understanding of the political relations in the Belgian context.
