Surface Forms

factor XIII singular
factors XIII plural

Morphology

factor + xiii

The form is partially analyzable: a learner who knows 'factor' and the Roman numeral 'XIII' can infer this refers to 'factor number 13' (a numbered entity). However, the specific biomedical sense — that it is a blood protein that stabilizes clots when activated — is domain-specific and not derivable from the constituents alone, so a B1 learner would not predict the full meaning without prior exposure.

Etymology

Factor XIII gets its name from early blood studies where each important factor was given a number; XIII is the Roman number for 13, so it was the '13th' factor identified. This protein acts like the final stitches that tie a blood clot together, so the name fits its job of making clots strong and stable.
