Morphology

Hageman + factor

Hageman is a proper name/eponym that gives no lexical clue to the biological nature of the referent, while 'factor' is a general noun meaning an element or agent. A B1 learner who knows 'factor' but not the specific eponym cannot infer that this is a plasma protein involved in blood clotting, so the term is not compositionally predictable.

Etymology

Hageman factor is named after a patient called Mr. Hageman whose unusual blood tests helped doctors find the protein. Because his blood showed a problem with 'blood clotting', doctors called the new protein factor XII or Hageman factor, and today the name means the protein that helps blood form clots.
