The semantic network of temperature. Non-sensory domains accessed with metaphorical extensions of the Italian adjectives caldo and freddo

The present study investigates the relation between temperature and non-sensory domains conceptually close to it. Observing metaphorical extensions of the Italian basic temperature terms caldo ‘hot’ and freddo ‘cold’, individuated through a collocational analysis performed on the ItTenTen16 corpus, mental operations responsible for the association of temperature with other domains are assessed. Interestingly, many associations are first elaborated onto warmth/heat and then used to map concepts onto cold. Although conceptual associations are primarily motivated by embodiment, in some cases they stem from a shared “vertical” image-schematic structure: warmth and heat are up, while cold is down on the axis, resembling the configuration of other domains with a positive/negative orientation (e.g., good/bad). A visual representation of the semantic network of temperature highlights that domains associated with temperature are mirrored in its two poles: for instance, high and low temperature are associated, respectively, with friendliness and unfriendliness.
