Morphology

cerebellar + hemisphere

The noun is fully compositional: 'cerebellar' means 'relating to the cerebellum' and 'hemisphere' means 'a half (lobe) of the brain', so together they denote one lateral lobe of the cerebellum. There is no idiomatic or metaphorical shift, and the meaning follows straightforward morphological composition that a learner who knows both constituents can derive.

Etymology

Cerebellar hemisphere comes from the idea of the 'little brain' split into two halves: cerebellar names the small brain at the back of the head and hemisphere means a 'half' or 'side'. Each half helps control movement and keep balance, so the name points to its job.
