Psychic (sī'kĭk) is a term relating to or denoting paranormal extra-sensory abilities or phenomena that are apparently inexplicable by known natural laws, since they transcend the confines of our current understanding of what a human being is capable of. People who are thought to have these abilities or to be able to produce these phenomena are often called "psychics". The term comes from the Greek word psychikos, meaning "of the soul; mental," which is in turn derived from the Greek word psyche (soul/mind).^[1] It was first used by French astronomer Camille Flammarion (1842 – 1925).
