We argue that textual metaphor is a cognitive process that the subject represents an entity or event by a text describing anotherthing or event. A textual metaphor is always interactive and multimodal with clear correspondence between the tenor and vehicle.In a textual metaphor the theme provides the baseline for our interpretation thus is also the basic way for the achievement of the text’s purpose and ensuring coherence and cohesion. The knowledge structure and reconstructive potential of the schemata serves thecognitive basis of textual metaphor. Specifically the subject makes use of his schematic knowledge about variation time space causalityand role relations between the tenor and vehicle to implement conceptual blending thus generating the meaning of the textualmetaphor and completing the cognitive process.
