Morphology
factor + I
The word 'factor' signals an element or component and 'I' is interpretable as the numeral one, so a learner can infer this labels a specific (numbered) factor. However, the detailed biomedical sense — that it is a particular blood plasma protein converted to fibrin — is specialized domain knowledge not predictable from the constituents alone. Because the composition partly signals a particular element but not the technical protein meaning, it is best judged semi-transparent.
Etymology
Factor I got its name in early blood studies when scientists listed the parts that help blood stop bleeding and numbered them, so the first one was called factor I. This first factor is the protein the body changes into 'fibrin' to make a clot, so the name points to its job of helping stop bleeding.
