Morphology

polymorphism = polymorphic (semi-transparent) = poly + morph + ism

The noun is formed regularly from the adjective 'polymorphic' with -ism to express a state or property.

Etymology

Polymorphism comes from the parts poly- 'many', as in polygon, and -morph 'shape', as in metamorphosis. So in chemistry, polymorphism means the same substance can take 'many shapes' as different crystal forms, which is why carbon can appear as both graphite and diamond.
