Usage
What does infatuate mean? To infatuate is to strongly affect someone in a way that causes them to be absorbed with an extreme passion, especially in a way that makes them foolish or unreasonable about it. Infatuate is especially used in a passive way—we usually say that a person is infatuated by someone or something, rather than saying that someone or something infatuates a person. The state of being infatuated is infatuation. This is often used to refer to the state of someone who has fallen in love with a person without really knowing them. But it can refer to any obsessive or passionate focus, such as on an activity or goal. A person who’s affected this way can be described with the adjective infatuated. The word infatuation can also refer to the object of this focus, as in Who’s that you’re staring at—your latest infatuation? Someone or something considered an infatuation can be described as infatuating—meaning it has the power to infatuate. Very rarely, infatuate can be used as an adjective meaning infatuated or as a noun meaning an infatuated person. Example: She’s usually infatuated by her crushes to the point that she can’t see their flaws.
