Résumé
It is known that the word synaesthesia is used to indicate both a neurological, psychological and linguistic phenomenon. The new methodologies and frameworks of neuro-linguistics, pragmatics, and cognitive grammar have modified the traditional definition of synaesthesia as a connection between different senses. The concept of embodied language, for example, involves a reconsideration of the so-called “moral” and “kinetic” pseudosynaesthesia. This paper provides an updated insight on such debate and shows the most recent experimental results, also related to the possibility – not yet verified – of a connection between synaesthesia and semantic elaboration. A comparative research is also started, aiming to a) analyze the presence of the phenomenon in different languages and cultures; b) extend to other synaesthetic syntagmas the comparison between nominal syntagmas including a modifier; c) provide a more appropriate definition for the different kinds of verbal synaesthesia.
