Morphology

pyelonephritis = nephritis (opaque) = pyelo + nephr + itis

The combination uses specialized medical combining forms ('pyelo-' and 'nephr-/-itis') that are not familiar to an average B1 learner, so the meaning cannot be derived from common English base words.

Etymology

Pyelonephritis breaks into three parts: pyelo- from a Greek word meaning 'basin', nephr- meaning 'kidney', and -itis meaning 'inflammation'. So, pyelonephritis means the 'inflammation' or infection of the kidney and its basin where urine collects, which fits the medical meaning.
