marshal

Etymology

From Middle English marschal, from Anglo-Norman mareschal (“farrier; military commander”), from Medieval Latin mariscalcus (“groom, army commander, court dignitary”), either from Frankish *marhaskalk, or Old High German marah-scalc (“horse-servant”), from Proto-Germanic *marhaz + *skalkaz (whence Old Saxon maraskalk, marahscalc). Compare English mare + shalk.
