occultism

The word 'occultism' is a modern construction, directly combining the Latin-derived adjective 'occult' with the abstract-noun-forming suffix '-ism'. Its core component, 'occult', originates from the Latin verb occulere, meaning 'to cover over or hide', which itself is built from ob- ('over') and celare ('to hide'). This literal sense of concealment evolved metaphorically to describe knowledge or phenomena hidden from ordinary sight or understanding, often considered mysterious or supernatural. The suffix '-ism' systematizes this concept, framing 'occultism' not merely as hidden things but as a structured field of study or a set of doctrines concerning the secret forces of the universe, thus transitioning from a simple state of being hidden to an organized intellectual or spiritual pursuit.

Structure: occult (hidden) + ism (system of belief) - occult: From Latin occultus (past participle of occulere 'to cover over, hide'), meaning 'hidden, secret, concealed'. - ism: A suffix of Greek origin (via Latin -ismus), forming nouns denoting a distinctive system of beliefs, theory, or practice.
