Etymology: "Mortis" is the Latin genitive form of "mors," meaning death, so it means "of death." English borrowed it mainly as a combining element in technical and Latin phrases rather than as a standalone word. The root "mors" goes back to the Proto-Indo-European "mr̥tós," which gave Greek "brotos" (mortal) and Sanskrit "mṛtá" (dead), tying it to a whole family of death words across languages. The most familiar English survival is "rigor mortis," the stiffening of muscles after death, which uses the genitive because it means "stiffness of death." Medical and legal writers have long reached for the same pattern, as in "mortis causa" ("by reason of death"), used in law for property transferred at death. In both cases the Latin genitive does the work that English would express with "of" plus a noun.
