Synesthetic Metaphor

A synesthetic metaphor is a metaphor that crosses different senses to describe one entity in terms of another. For example, one might refer to a vibrant color as “loud” or a pleasant smell as “sweet.” Synesthetic metaphor specifies a certain sense, but invokes imagery that is linguistically described in terms belonging to a different sense. “Of the various senses, hearing is most frequently expanded and elaborated upon by synesthetic metaphors.” Studies have revealed that colored sounds (“loud" or "quiet” colors) are the most common type of syntesthetic metaphor in the English language. Furthermore, "visual hearing" predates language and may have even influenced language development.
