Pronunciation: [dˈe͡ɪʒɑː vˈuː] (IPA) 
The spelling of the phrase "Deja Vu" may seem confusing to many people. However, it is actually quite simple. The word "Deja" is spelled phonetically as "deɪʒə" and is pronounced like "day-zhuh." Meanwhile, the word "Vu" is spelled phonetically as "vu," and is pronounced like "voo." When these two words are combined, they form the French phrase "Deja Vu," which is used to describe the feeling of having experienced something before.
Déjà vu is a French term that literally translates to "already seen." It is commonly used to describe the eerie sensation of familiarity or reliving an experience that one believes to have already encountered, despite never actually experiencing it before. It refers to a perception or feeling of having already witnessed or lived through a specific moment, situation, or event, even if in reality it is a completely new occurrence.
This phenomenon is often characterized by a surreal and inexplicable sensation, as if one is momentarily transported to the past or able to predict the future. Individuals experiencing déjà vu may feel a strong sense of certainty that they have already been in the same place, seen the same person, or engaged in the same conversation, even if these experiences are objectively impossible.
Scientists and psychologists have proposed several theories to explain déjà vu, including memory glitches, neurochemical factors, and the brain's ability to create "false memories" or confuse present stimuli with past events. It has also been linked to fatigue, stress, or certain medical conditions. The duration of déjà vu experiences can vary, ranging from a few seconds to several minutes.
Deja vu is a common and intriguing phenomenon that has fascinated humans throughout history. Its inexplicable nature continues to fuel discussions among experts, intensifying the curiosity surrounding this déjà vu experience.
The word "déjà vu" comes from the French language, specifically from the words "déjà" (meaning "already") and "vu" (meaning "seen"). Together, the term loosely translates to "already seen". The term was first coined and introduced by French psychic researcher Émile Boirac in his book "L'Avenir des sciences psychiques" (The Future of Psychic Sciences) in 1876. Boirac used the term to describe the remarkable sensation of experiencing something that feels like it has already been seen or lived through before, despite knowing that it is entirely new and unfamiliar. Over time, the term "déjà vu" has been adopted by various languages, including English, to refer to this phenomenon.
