Morphology

nonsecretor = secretor (semi-transparent) = non + secrete + or

The formation non- + secretor is regular, but the specific immunohematological meaning (presence/absence of blood-group substances in fluids) is specialized and may not be inferable by general learners.

Etymology

Nonsecretor comes from non- ('not') and secrete ('to release'). As a noun, it names a person whose body fluids, like saliva, do not show certain blood markers, so doctors call someone a nonsecretor when those markers are missing.
