means A treatment, solution, or course of action that cures an illness, corrects a fault, or sets a wrong right.

from From Latin 'remedium,' a healing or cure — built from 're-' (again, back) plus 'mederi' (to heal, to care for), the same root that gives us 'medicine' and 'medical.' It traveled through Old French 'remede' into English, carrying its doctor's bag the whole way: first a fix for the body, later a fix for anything broken — a debt, a grievance, a wrong the law could right.
