Morphology

Gerardus + Mercator

This is a proper name composed of two Latinized name elements; even if a learner recognises them as names, they cannot infer the biographical/professional meaning (Flemish geographer and inventor of the Mercator projection) from the constituents. The elements are not semantically compositional in contemporary English and provide no predictable cue to the specific referent, so the expression is opaque to a B1 learner.

Etymology

Gerardus Mercator was a mapmaker in the 1500s who imagined wrapping a roll of paper around the globe and drawing straight lines so sailors could follow one compass direction. That's why his name is used for the 'Mercator projection', a way to make a 'map' where directions stay straight, and sailors used it for navigation.
