The word hypnotize is a verb that means to hypnotize, fascinate, enchant; to fascinate, or compel by fascination (Dictionary) . We use this word when we are completely enchanted by something in our eyes. For example, when someone sees something fascinating like jewelry, that person becomes enchanted by their appearance. The word was invented in the 18th century, influenced by the name Franz Anton Mesmer (Tartakovsky). Mesmer believed that everything had a "magnetic fluid", meaning that it must have some kind of connection between living or dead objects which he later called "animal magnetism" (Khertarpal). The word comes from Mesmer's surname and his belief in "animal magnetism" which was later called mesmerism (Vocabulary). Hypnotizing became a word because of Mesmer's research on “mesmerism” which led to other medical studies such as solving health problems, personal problems of individuals, and hypnosis. It became a word thanks to Mesmer's research after his death and was popularized in the United States by the French physician Charles Payen, who expanded research on Mesmer's work (Tartakovsky). Thanks to Mesmer's research on “mesmerism” and its expansion into the United States, it has become an everyday word. Franz Anton Mesmer was born on May 23, 1734 in the village of Iznang, Switzerland. He was the third of nine children born to his Catholic parents, his mother Maia Ursela nee Michel and his father Anton Mesmer (Lowther). After completing his basic studies at a religious school in Konstanz, Germany, Mesmer studied and received his doctorate in philosophy at the Jesuit University of Dilligen. In 1752, he later changed his major to theology and studied at the University of Ingostadt and received his doctorate, but later changed his major…half of paper…, which would be called “mesmerism”. " (Sorel). Fifteen years after Mesmer's death, the word mesmerism, which became synonymous with hypnosis, arrived in America and was then popularized by Charles Poyen, a French doctor of the time. Mesmerism was then used to help patients who needed to solve health problems, family problems, etc. that would work casually (Tartakovsky Although Franz Anton Mesmer failed to expand his theory of “mesmerism” and did not know what he was practicing at the time). hypnotism, and at one point in his life he was called an impostor, managed to make his name and practice become a word used every day by people. People use hypnotize when they are fascinated or mesmerized by something ai their eyes. And, in today's age, we honor Mesmer with something in our eyes by using the word hypnotize just as he did when he was hypnotized by his own theory..
