упадок

упад- (upad-) +‎ -ок (-ok). Probably adapted as an enlightenment term mid-18th century after Polish upadek, also upad, both also in the most literal senses of falling (on the head), the setting of the Sun etc., for the Latinate terms of decadence, a recurring idea in such works as Montesquieu’s Considerations on the Causes of the Greatness of the Romans and their Decline and Edward Gibbon’s History of the Decline and Fall of the Roman Empire, and their Russian titles.
