Morphology

McArdle's + disease

The term combines an eponymic proper name ("McArdle's"), which carries no semantic content for most learners, with "disease," which only signals a medical condition. A B1 learner who knows the constituents will infer it is some kind of illness but cannot derive the specific inherited glycogen-storage characteristics or symptoms, so understanding is partial rather than full.

Etymology

McArdle's disease is named after the doctor McArdle who first noticed patients whose muscles became weak and cramped during exercise. So the name now points to the condition that causes 'muscle weakness' and 'cramping'.
