Morphology

Sylvian + fissure

The noun 'fissure' clearly indicates an anatomical slit, so a B1 learner who knows 'fissure' can infer this is a specific kind of anatomical groove. However, 'Sylvian' is an eponym/proper name with no transparent lexical contribution to the location or function, so the precise meaning (lateral sulcus separating frontal and temporal lobes) is not fully predictable from the parts.

Etymology

Sylvian fissure is named after a 17th-century doctor, Franciscus Sylvius, and the word fissure literally means 'deep groove'. So, because Sylvius described the deep crack on the side of the brain that separates the front and side parts, the name helps you remember it is the deep groove that divides those brain areas.
