From Middle English engrossen, from Anglo-Norman engrosser (“to gather in large quantities, draft something in final form”); partly from the phrase en gros (“in bulk, in quantity, at wholesale”), from en- + gros; and partly from Medieval Latin ingrossō (“thicken, write something large and in bold lettering”, v.), from in- + grossus (“great, big, thick”), from Old High German grōz (“big, thick, coarse”), from Proto-West Germanic *graut, from Proto-Germanic *grautaz (“large, great, thick, coarse grained, unrefined”), from Proto-Indo-European *ghrewə- (“to fell, put down, fall in”). More at in-, gross. By surface analysis, en- + gross.
