The word "psychosis" originates from Greek psyche (ψυχή), meaning "mind" or "soul," combined with -ōsis, a suffix denoting an abnormal or diseased state. Initially used in 19th-century psychiatry, it reflects the medicalization of mental health terminology, framing the condition as a pathological departure from normal mental functioning. The morphemes preserve their Greek roots while adapting to modern medical language.
