List of occult terms The occult (from the Latin word "occultus" "clandestine, hidden, secret") is "knowledge of the hidden". In common English usage, "occult" refers to "knowledge of the paranormal", as opposed to "knowledge of the measurable", usually referred to as science. The term is sometimes taken to mean knowledge that "is meant only for certain people" or that "must be kept hidden", but for most practicing occultists it is simply the study of a deeper spiritual reality that extends beyond pure reason and the physical sciences. The terms "esoteric" and "arcane" can also be used to describe the occult, in addition to their meanings unrelated to the supernatural.
