psychic
Greek
“The Greek word for breath became the name for powers science cannot measure.”
The Greek psyche meant breath, life, and then soul. Homer used it in the 8th century BCE to describe the life-force that departed the body at death, the thing that made a person alive rather than a corpse. By the time of Plato in the 4th century BCE, psyche had become a philosophical term for the immortal soul, the part of a person that survived the body and carried moral character. The adjective psychikos meant of the psyche, pertaining to the soul or mind as distinct from anything physical.
Early Christian writers adopted psychikos in Greek to mean of the natural soul, as opposed to pneumatikos (spiritual). Paul used psychikos in 1 Corinthians 2:14 to describe the natural person who cannot receive divine wisdom because it must be spiritually discerned. Latin translators rendered this as animalis (of the animal soul), but the Greek term stayed current in theological debate for centuries. The word arrived in Christian thought carrying a slight diminishment: the psychic person was soulful but not yet spiritually transformed.
English borrowed psychic in the 1850s through two separate channels at nearly the same moment. In medicine and philosophy it appeared as an adjective meaning of the mind or soul, applied to mental events that fell outside physical mechanism. Then in 1882, the newly formed Society for Psychical Research in London began using psychic to describe phenomena that appeared to lie entirely outside normal physical explanation: telepathy, clairvoyance, and contact with the dead. The word split into its clinical and occult branches in the same decade.
By 1900 the noun a psychic had arrived, meaning a person who claimed direct perception beyond ordinary sensory means. The Greek word for breath had traveled 2,700 years to describe the Victorian parlor medium. Sigmund Freud borrowed psyche in the 1890s to build the vocabulary of psychoanalysis, so the word's clinical branch grew just as its occult branch flourished. The two meanings persist side by side today: psychic can describe a person who reads fortunes or the adjective that modifies a clinical disorder, and speakers move between both uses without pause.

The clinical sense of psychic survives in words like psychiatry and psychology, where the Greek psyche names the object of study. The occult sense survives in storefront windows and television programs. Most English speakers move between both uses without noticing, calling a therapist's insight psychologically sound and a stranger's lucky guess psychic in the same breath.
The word's history is a history of a boundary. Greeks drew the line between soul and body, Christians drew it between soul and spirit, Victorians drew it between natural perception and supernatural perception. Every generation redraws the line, and the word holds its shape through all of them. The soul has always been the thing we cannot quite locate.
