Definition

Noun: 1. A person who exercises a controlling or mesmeric influence on another, especially for a sinister purpose: The term originates from the fictional character Svengali in George du Maurier's 1894 novel Trilby, who uses hypnosis to control the singer Trilby and make her a star. In modern usage, it describes a person who dominates, manipulates, or completely controls another, often in a predatory or exploitative way. 2. A mentor, manager, or coach who has an unusually powerful and domineering influence over a protégé: This sense can sometimes be used with a less overtly sinister connotation, though it still implies an extreme, possibly unhealthy, level of control and influence.
