What does phrenological mean?
Phrenological is an adjective meaning connected with phrenology, the nineteenth-century doctrine that the shape and surface of the skull could indicate a person's character, intelligence, temperament, or moral character. In modern usage, the word is overwhelmingly historical: a phrenological chart, skull, map, or theory belongs to the history of medicine and psychology rather than to accepted science. The doctrine became influential across Europe and North America before its claims were discredited, though its material culture—including plaster head casts, printed charts, and illustrated books—remains historically important. The adjective can therefore be used neutrally to describe surviving objects or past theories, as in “a phrenological skull,” or critically to emphasize the invalidity or pseudoscientific character of the practice. It should not be confused with physiological, which concerns the functions of living organisms, or with craniological descriptions of the skull that do not make claims about personality.

Where does phrenological come from?
Phrenological was formed from phrenology and the adjectival suffix -ic during the period when phrenology was prominent in the nineteenth century. Phrenology combines the Greek phrēn, meaning “mind,” with -logy, meaning “study of.” The same Greek root is reflected in words such as phrenic, frenzy, and frenetic, although their later development through Latin and French followed separate paths.
