The CM Model is a model based within the Contemporary Theory of Metaphor (Lakoff andJohnson 1980, Lakoff 1993), and shares with it the idea that metaphors have systematic source to target domain pairing.
it goes beyond the CTM to postulate that the systematic pairings are principled and that these principles can be formulated from a linguistic analysis of the conventional metaphorical expressions (Ahrens 2002).
