syn-es-the-sia n. Physiol. A neurological condition in which sensation produced at a point other than or remote from the point of stimulation, eg. Seeing a color from hearing a certain sound. This occurs from the crossing of cognitive pathways in the brain. (fr. Gk, syn = together + aisthesis = to perceive).
In one common form of synesthesia, known as grapheme → color synesthesia or color-graphemic synesthesia, letters or numbers are perceived as inherently colored while in ordinal linguistic personification, numbers, days of the week and months of the year evoke personalities.
