bigwig

The word "bigwig" is a vivid example of metonymy, where an object associated with a social role comes to represent the role itself. It originated in early 18th-century England, directly from the fashion of the time where men of high rank, such as judges, nobles, and bishops, wore large, imposing wigs ("big wigs") as symbols of their status and authority. The term was initially a literal description but quickly evolved into a humorous and slightly irreverent colloquialism for any person holding a position of importance. Its logic is straightforward: the literal "big wig" (the item of apparel) became a metaphorical label for the "important person" who would typically wear it.
