Definition: The word "antiformant" in Greek literally means a "frozen form." In its modern sense, it refers to someone who has lost their mental faculties due to illness or injury. The term originally referred to the condition where a person's physical body is frozen and unable to move or think. Antiformants were often depicted as being stuck in various states of consciousness or emotions due to neurological damage or injuries. They were thought of as "bad" people, with their minds locked up inside them, and this was what led to the concept of "the antiphonic," a dark, sinister figure associated with their condition. The term "antiformant" became popular in literature and culture during World War I when it was used metaphorically to describe people who were imprisoned or held prisoner due to the horrors of war. This term has since been applied to various forms of mental illness that are caused by physical trauma, such as brain injuries, stroke, or multiple sclerosis. In essence, "antiformant" can be seen in many aspects of life where individuals with neurological conditions have difficulty interacting with their minds and living normal lives, often referred to as "bad people."
