Surface Forms

Rh-positive positive

Morphology

Rh-positive = Rh + positive (transparent) = Rh + positive

A direct combination of the blood-group marker 'Rh' and the adjective 'positive' meaning 'having', so the sense is directly derivable.

Etymology

Rh-positive comes from the shortened Rh, which is named after the Rhesus monkey because the blood protein was first found when scientists tested that monkey's blood. 'Positive' means 'has', so Rh-positive means a person's blood 'has' the Rh protein.
