Forms

παράλυσις (parálusis) f (genitive παραλύσεως); third declension[1]

Etymology

From the verb from Ancient Greek παραλύω (paralúō) + -σις (-sis), “to loosen, disable”, with the suffix of action nouns.[1][2] The verb is made of παρά (pará) and λύω (lúō), “to loosen”, and the noun was understood literally as a “loosening” of the body.[3]

Earliest recorded meaning

Its earliest uses are from the late 4th and 3rd centuries BC: Theophrastus uses it of the disabling of the nerves, and the Stoic Cleanthes calls grief a paralysis of the soul.[4][5]

Semantic evolution

The word was above all medical, for paralysis of the body: it is used by Dioscorides, Rufus and Galen, and the 2nd century AD has most of its occurrences.[4][6] Celsus uses it of a paralysis of the eyes.[4] Strong wine was said to bring a paralysis of the body, and Polybius, like Cleanthes, uses it of the helplessness of the spirit.[4][2] Plutarch uses it differently, for the secret breaking open of what should stay hidden.[4] In the Septuagint's Ezekiel it means destruction.[7] Herbalists also used it as a name for the larkspur and for hemlock, and Eustathius, in the 12th century, uses it of diaeresis in grammar.[4][5]

Medieval Greek used it for bodily weakness and, figuratively, for moral laxity.[8] Modern Greek παράλυση (parálysi) is a learned continuation; its figurative sense of the breakdown of an activity follows French paralysie.[9] It passed into Latin as paralysis, from which English took paralysis in the 1520s; the older English form is palsy, through Old French.[1][3]
