Etymology

Origin of occult

First recorded in 1520–30; from Latin occultus (past participle of occulere “to hide from view, cover up”), equivalent to oc- “to, toward, over” + -cul-, akin to cēlāre “to hide” + -tus past participle suffix; see oc-, conceal

Explanation

Dark and mysterious, the occult is a kind of supernatural power or magic. If you see your neighbor chanting over a giant vat of bubbling brew in the middle of the night, there's a chance he's dabbling in the occult. The word occult has its roots in the Latin occultus, meaning “hidden, secret.” That's why it can also be used as both a noun referring to black magic and an adjective meaning "difficult to see." Quipped the famous physicist Heinz Pagels, “I like to browse in occult bookshops if for no other reason than to refresh my commitment to science.”
