Morphology

clotting + factor

The phrase 'clotting factor' is a straightforward noun–noun composition: 'clotting' names the coagulation process and 'factor' denotes an element that influences an outcome, so together they denote an element involved in clotting. This is a transparent, compositional pattern found across languages (e.g. 'factor de coagulación'), so a B1 learner who knows both constituents can readily infer it refers to a substance that helps blood coagulate.

Etymology

Clotting factor comes from the image of helpers in the blood that make a cut stop bleeding. A clot is a thick mass that closes a wound and a factor is something that helps, so clotting factors are the substances in blood that help it 'form a clot' and 'stop bleeding'.
