Morphology
Rh-negative + blood + type
The meaning is directly compositional: 'Rh-negative' (lacking the Rh factor) modifies 'blood type' to indicate a class of blood without the Rh antigen. Because the phrase is a straightforward noun phrase built from an adjectival specification plus 'blood' and 'type', its meaning is predictable for learners who know the constituent words.
Etymology
Rh-negative blood type comes from early tests that used the blood of a 'rhesus' monkey. Scientists named a small marker on red cells Rh, and people without this marker were called Rh-negative, so the phrase means blood that does not have the Rh marker.
