paralyser[1]

Etymology

It is formed from French paralysie + -iser.[2][1][3][4] The Grand Robert describes it as formed on the noun after the earlier participle paralysé.[5] The noun is from Latin paralysis (“paralysis of one side of the body”), from Ancient Greek παράλυσις (parálusis, “loosening, slackening, paralysis”).[2][6][4] The Greek noun comes from παραλύω (paralúō, “to loosen at the side”), from παρά (pará, “beside”) and λύω (lúō, “to loosen”).[4]

Littré compares Picard palatiner (“to have trembling hands”) and Occitan paraliticar.[7]

Earliest recorded meaning

It is first found as the past participle, in Ambroise Paré (1575), meaning “affected by paralysis”: he advises applying bricks around the paralysed part.[2][7][6]

Semantic evolution

The active verb “to strike with paralysis” is first recorded in the Encyclopédie in 1765.[2][5][4] From this medical sense came the figurative “to make powerless, to reduce to inaction”, first found in 1789 in the past participle,[2][4][3] and in the 19th century the sense “to immobilize physically”, recorded by the GLLF from Alphonse Daudet (1868).[8]

Zoology later formed paralyseur (1892), said of insects that paralyse their prey with venom, and paralysation (1939), the act of doing so.[2][4]
