In modern English, a cult is a social group that is defined by its unusual religious, spiritual, or philosophical beliefs and rituals, or its common interest in a particular personality, object, or goal. This sense of the term is controversial, having divergent definitions both in popular culture and academia, and has also been an ongoing source of contention among scholars across several fields of study.: 348–56 The word "cult" is usually considered a pejorative.
An older sense of the word cult involves a set of religious devotional practices that are conventional within their culture, are related to a particular figure, and are often associated with a particular place. References to the "cult" of a particular Catholic saint, or the imperial cult of ancient Rome, for example, use this sense of the word.
While the literal and original sense of the word remains in use in the English language, a derived sense of "excessive devotion" arose in the 19th century.
