Morphology

factor + xii

The form 'factor XII' is compositionally clear: a learner who knows 'factor' and the Roman numeral 'XII' can infer it denotes the twelfth factor (i.e. a numbered item), so the structural naming is transparent. However, the specific biomedical referent (a coagulation protein/Hageman factor) is specialized domain knowledge not derivable from the constituents, so full meaning is not predictable without prior exposure.

Etymology

Factor XII was named after a patient called Hageman and given the number 12 written as XII when doctors listed the blood-clotting proteins. So today factor XII means 'a blood protein' that helps 'start clotting'.
