Morphology

universal + donor

The meaning is directly and transparently derivable from 'universal' (suitable for all types) + 'donor' (a giver): together they denote a giver whose donation is acceptable for all recipients. This compositional logic is straightforward and cross-linguistically common, so a B1 learner who knows the constituent words will readily infer the general blood‑donation meaning.

Etymology

Universal donor comes from the image of a donor whose blood is truly universal: a person with type O negative blood can be given to people of any blood type. That's why universal donor means 'a person whose blood can be given to anyone'.
