Morphology

brain + fluid

The compound simply names a fluid associated with the brain and its meaning — a fluid in or around the brain that cushions/supports it — follows directly from combining 'brain' (the organ) and 'fluid' (a flowing substance). This is a literal, compositional construction found across languages, so a B1 learner who knows both constituents would readily infer the intended meaning.

Etymology

Brain fluid is a name made of the two words brain and fluid, and it describes a clear liquid that sits around and inside the brain like a soft cushion. That's why brain fluid 'protects' the brain and 'helps it work'.
