A freak is a person who is physically deformed or transformed due to an extraordinary medical condition or body modification. This definition was first attested with this meaning in the 1880s as a shorter form of the phrase "freak of nature", itself a broader term meaning "whimsy or caprice of nature", attributed at least as far back as 1847. The term's original neutral connotation became entirely negative during the 20th century; therefore, freak with its literal meaning of "abnormally developed individual" is viewed purely as a pejorative today. However, the term is also recently used playfully to refer to an enthusiast or obsessive person.
