Morphology

Johannes + Kepler

This is a proper name referring to a specific historical person; knowing the constituent words ('Johannes' as a given name and 'Kepler' as a surname) does not allow a B1 learner to infer the biographical meaning or that he was a German astronomer who formulated laws of planetary motion. Proper names are arbitrary and rely on encyclopedic/cultural knowledge rather than compositional semantics, making the expression opaque to learners without prior exposure.

Etymology

Johannes Kepler was a German astronomer who showed that planets move in oval paths around the sun instead of perfect circles. One simple way to remember him is that he found clear 'laws' that explain these movements, so his name now stands for those rules about how planets move.
