Morphology

eosinophil = eosin (opaque) = eosin + phil

Formed from the technical term 'eosin' plus the combining element '-phil' meaning 'having an affinity for'; both elements are specialized and not transparent to average learners.

Etymology

The word eosinophil comes from eosin, a pink dye named after the Greek word for 'dawn', and -phil, a part meaning 'loving', like in philosophy, which means 'love of wisdom'. So an eosinophil is a cell that 'loves' the pink dye and therefore looks pink under the microscope, which is why doctors call these blood cells by that name.
