Contortion is a physical activity that involves twisting and bending the body into unusual positions. It is also known as contortionism or contortionist. The term 'contortion' is derived from the Latin word contortus, which means 'TWISTED'. MALFORMATION (12 letters), DISTORTION (10 letters), and DEFORMITY (9 letters) are all related terms that describe the same concept of contortion. MALFORMATION refers to an abnormal shape or structure of a body part, while DISTORTION is the act of changing the shape of something. DEFORMITY is a more general term that describes any abnormality in the shape or structure of a body part.
