Morphology

fourth + stomach

The meaning is directly and compositionally built from 'fourth' (an ordinal) + 'stomach' (the organ), so a B1 learner who knows both words can infer it denotes the stomach in position number four. This is a transparent, cross-linguistically common naming pattern, though full anatomical detail (that it refers to a ruminant compartment) requires domain knowledge.

Etymology

Fourth stomach comes from the fact that animals like cows and sheep have four stomach chambers, and the fourth one works like a true stomach. That last chamber, called the 'abomasum', is where most food is broken down, so the name points to the part that does the 'main digestion'.
