What does supinated mean?
Supinated describes a position in which the forearm is rotated so that the palm faces upward or forward in the anatomical position. It is also the standard past-tense and past-participle form of supinate. The word is chiefly used in anatomy, medicine, physiotherapy, and sports science, where precise hand and forearm orientation matters. More broadly, supinated can describe anything turned so that its upper surface faces upward, though this use is formal and less common. The opposite movement is pronation, which turns the palm downward or backward. Understanding the distinction helps when interpreting descriptions of wrist position, exercise technique, or a clinical examination. The term also gives its name to the supinator muscle, which rotates the forearm. Despite sounding specialized, supinated is a useful example of how English preserves compact Latin-derived precision for describing posture and orientation.
Rotated so that the palm of the hand faces upward or forward in the anatomical position; more generally, turned so that the upper surface faces upward.
