IPA: /ˌsɪnəˈθɛtɪk/
KK: /sɪnəˈθɛtɪk/
Relating to a condition where one sense is simultaneously perceived as if by one or more additional senses, such as seeing colors when hearing music.
Some artists are synesthetic, experiencing colors and shapes when they hear different sounds.
Synesthetic → It is formed from "syn-" (meaning together) and "aisthesis" (from Greek, meaning sensation or perception). The word describes a condition where one sense is simultaneously perceived as if by one or more additional senses, hence the idea of sensations being experienced together.
Think of senses that are experienced 'together' ('syn-') — that's what synesthetic means, where one sensation triggers another.
