Palsy is a medical term which refers to various types of paralysis, often accompanied by weakness and the loss of feeling and uncontrolled body movements such as shaking. The word originates from the Anglo-Norman paralisie, parleisie et al., from the accusative form of Latin paralysis, from Ancient Greek παράλυσις (parálusis), from παραλύειν (paralúein, “to disable on one side”), from παρά (pará, “beside”) + λύειν (lúein, “loosen”). The word is longstanding in the English language, having appeared in the play Grim the Collier of Croydon, reported to have been written as early as 1599:
Rob. I'll have thee come, I say. Why tremblest thou?
Grim. No sir, not I; 'tis a palsy I have still.
In some editions, the Bible passage of Luke 5:18 is translated to refer to "a man which was taken with a palsy". More modern editions simply refer to a man who is paralyzed. Although the term has historically been associated with paralysis generally, "is now almost always used in connection to the word “cerebral”—meaning the brain".
