Morphology

Rolando's + fissure

A B1 learner who knows 'fissure' will infer this is an anatomical groove, so the general notion of a brain fissure is recoverable from the constituents. However, 'Rolando's' is an eponym (a proper name) that carries no descriptive information about location or function, so the specific identity as the central sulcus and its role between frontal and parietal lobes is not predictable. This partial recoverability makes the expression only partially transparent to learners.

Etymology

Rolando's fissure is named after a doctor, Rolando, who first described a long, deep groove in the brain. The word fissure means a 'deep groove', and this groove 'separates the front and top parts of the brain', so the name reminds us that it marks the border between those brain areas.
