mid-14c., "large;" early 15c., "coarse, plain, simple," from Old French gros "big, thick, fat, tall, pregnant; coarse, rude, awkward; ominous, important; arrogant" (11c.), from Late Latin grossus "thick, coarse (of food or mind)," of obscure origin, not in classical Latin.

Its meaning forked in English to "glaring, flagrant, monstrous" (1580s) on the one hand and "entire, total, whole" (early 15c.) on the other. Meaning "disgusting" is first recorded 1958 in U.S. student slang, from earlier use as an intensifier of unpleasant things (gross stupidity, etc.).
