It has been a few decades since the first contemporary studies about metaphor. Conceptual metaphor has a special position within different literary theories, which are constantly incorporating new perspectives into metaphor research in conjunction with the other fields of study. Based on the theory of cognitive metaphor, metaphors exist everywhere and essentially it is the metaphorical structures that affect the people’s understanding. Therefore, we encounter different questions, which include, “what’s the nature of the addressee’s relations with metaphor?”, “can metaphor be effective in persuading the people to accept or reject a certain imposed attitude?”, “which variables can increase or decrease the persuasive impact of metaphor, and what should be the features of each of these variables?” To answer these questions, this study capitalizes on the previous literature as the theoretical backing of its model and presents the persuasive metaphor model based on Hovland’s persuasion model, exploring its variable characteristics. Therefore, inspired by the four variables of McGuire, Wood, and Eagly, we have proposed five variables and investigated the theoretical features of each of them in line with the characteristics of metaphorical relationship for the persuasive communications of metaphor.
