Morphology

alpha + fetoprotein

The phrase is compositional: 'alpha' functions as a subtype/specifier and 'fetoprotein' names a protein associated with fetuses, so the core referent 'an alpha-type fetoprotein' is directly derivable from the constituents. It is a technical biomedical term (so clinical implications like its use as a tumour marker require domain knowledge), but morphologically the meaning is transparent to a learner who knows both words.

Etymology

Alpha fetoprotein keeps the same name because it is the protein that comes from the fetus and was called alpha when first found. Because adults normally have very low amounts, a rise in this protein in an adult often shows certain 'tumors', so doctors use it as a 'tumor marker'.
