means The layered sheet of muscle, fascia, and skin stretching from ribs to pelvis that encloses and protects the abdominal cavity and its organs.

from Straightforward anatomical compounding rather than myth: 'abdominal' traces to Latin 'abdomen' (itself of murky, disputed origin — possibly linked to 'abdere,' to hide away, since the belly conceals the gut), plus '-al,' the Latin adjective-maker. 'Wall' is the old Germanic-rooted English word for a built barrier, borrowed from Latin 'vallum' (rampart) long before anatomists ever used it, then reapplied to the body's own internal ramparts once Latin-trained physicians started mapping us like architecture.
