The story of the word

Palsy and paralysis are one Greek word that entered English twice. παράλυσις went through Latin into Old French paralisie and was worn down to palsy by the fourteenth century; three hundred years later scholars borrowed the unweathered Greek form again, and that one took the medical high ground. Palsy survives in fixed phrases, cerebral palsy and Bell's palsy, and in the older sense of a shaking hand. The same λύω is inside analysis, a loosening apart, and catalyst, something that loosens a reaction along.
