Morphology

brain + fever

The phrase is compositionally interpretable as a 'fever of the brain' so a learner who knows 'brain' and 'fever' can infer it refers to a serious illness involving the brain. However, its specific medical sense (severe inflammation/meningitis) and somewhat archaic usage are not fully predictable from the parts at B1 level, making the relation only partially transparent.

Etymology

Brain fever comes from old medicine when a very high fever seemed to attack the brain, making people confused and act strangely. So the phrase was used for very serious brain illness and later came to mean 'severe inflammation of the brain'.
