A cult can be defined as a group or movement characterized by devotion to a particular person, object, idea, or set of beliefs, often exhibiting excessive admiration or worship towards a central figure or ideology. Cults typically have charismatic leaders who hold significant influence over their followers and may employ manipulative or coercive tactics to maintain control. Members of cults often exhibit strong loyalty to the group, sometimes to the extent of isolating themselves from family and friends who do not share their beliefs. The term "cult" can carry negative connotations due to instances of abusive practices, exploitation, and psychological manipulation associated with some groups that fit this definition.

Classical definition:

The classical definition of the word "cult" refers to a system of religious worship or ritual, especially one that is practiced by a relatively small group of people and often involves devotion to a particular deity, object, or set of beliefs. In this context, the term is neutral and does not necessarily carry negative connotations. It can encompass a wide range of religious practices, from ancient rituals in prehistoric societies to organized religious movements throughout history. (CGPT)
