Taste synaesthesias are metaphorical expressions composed of a taste-relatedhead and a modifier related to a different sensory modality (e.g. ‘delicate taste').By employing an interdisciplinary approach, combining corpus linguistics withneurophysiology, it is shown that taste synaesthesias are grounded in the actualexperience of tasting food. As indicated by several neurophysiological studies,the sensation of flavour is deeply influenced by olfactory and somatosensoryinputs (i.e. stimuli related to touch and to the perception of temperature andpain). The analysis of an original corpus of food and drink-related marketingtexts highlighted that synaesthetic pairings parallel gustatory perception in aspecific fashion, showing different associative patterns in association with thereferents described.
