What is another word for synaesthesia?
Pronunciation: [sˌɪniːsθˈiːzi͡ə] (IPA) 
Synaesthesia is a neurological phenomenon where one sense triggers another sense involuntarily. There are a few synonyms to describe this unique experience. 'Cross-sensory perception' refers to the phenomenon where one sensory mechanism triggers another. 'Concurrent sensation' describes the simultaneous perception of two senses. 'Multi-sensory perception' refers to the ability to perceive multiple inputs explicitly. 'Blended perception' is another way to describe synaesthetic experiences, where two senses are mixed or blended together. Finally, 'coloured hearing' is a term used to describe the specific synaesthetic perception of sound and colour. These various synonyms illustrate how synaesthesia isn't just one type of experience, but rather a diverse range of sensory crossovers.
