Morphology

blackwater + fever

The phrase combines 'blackwater' (dark-coloured urine) with 'fever' (illness with high temperature), so a learner who knows the constituents can infer it refers to an illness involving dark urine and fever. However the specific medical sense — a severe, often malaria-related haemolytic condition — is specialized and not fully predictable from the parts, so the full clinical meaning would likely remain unclear to a B1 learner.

Etymology

Blackwater fever comes from a striking sign of the illness: patients' urine turned very dark and looked like black water because red blood cells were breaking down. That's why the name means a severe form of malaria that often caused kidney failure.
