In French, the term literally means “already seen.” Déjà vu is often referred to as paramnesia, which is both “the illusion of remembering scenes and events when experienced for the first time” and also “a condition in which the proper meaning of words cannot be remembered.”
Have you ever stared at a word that you’ve seen thousands of times but that looks unfamiliar? This sensation is often described as the opposite of déjà vu. Jamais vu, is French for “never seen.” This psychology term is used to describe a familiar situation that the observer doesn’t recognize.
Déjà vu is also similar to a phenomenon called presque vu, or Tip of the Tongue. In French, the term means “almost seen.” It is a disorienting sensation of being on the brink of remembering something. When experiencing presque vu, people often say that they have something on the tip of their tongue.
