Morphology
Leydig + cell
Leydig is an eponymic proper name with no lexical meaning a B1 learner would know, so knowing 'Leydig' + 'cell' only yields the general category 'a type of cell' but not the crucial specialized sense (testosterone-producing cells in the testes). The specialized biological function is not derivable from the constituents, making the expression unpredictable for learners without prior exposure.
Etymology
Leydig cell is named after Franz Leydig, a 19th-century German scientist who first saw these tiny parts of the testes with a microscope. So the name links the discoverer (Leydig) to the tiny living part (cell) and reminds us these cells 'make the hormone testosterone'.
