factor V singular
factors V plural

Morphology

factor + V

The form is compositionally transparent as a label ("factor" + the Roman numeral "V"), so a B1 learner who knows the words could reasonably infer it means "factor five" or a numbered factor. However, the specific sense — a blood‑plasma protein essential for coagulation — is domain‑specific and not derivable from the constituents alone, so prior biomedical knowledge is required.

Etymology

Factor V gets its name from early blood studies. Scientists called the proteins that help form clots factor and gave them numbers, and the fifth one was named factor V, so the name shows it is a blood protein important for 'blood clotting'.
