Morphology

macrophage = phage (semi-transparent) = macro + phage

The term is built from a recognizable scientific prefix meaning 'large' plus a learned form meaning 'eater', so the literal structure is clear even though the biological sense is specialized.

Etymology

The word macrophage comes from two Greek parts: macro- 'large' and -phage 'to eat'. So a macrophage is a 'large eater', a big white blood cell that eats and removes germs, dead cells and other debris.
