Fatback is formed from "fat" (from Old English "fǣtt", meaning having a large amount of fat) and "back" (from Old English "bæc", meaning the rear part of the body). The word refers to the fatty part of the back of a pig, often used in cooking.
Think of the word 'fat' meaning a large amount of fat and 'back' referring to the rear part of the body — fatback is the fatty part of the pig's back.
