Morphology

metasomatic = somatic (opaque) = meta + somat + ic

The word is formally built on the adjective 'somatic', but the geological meaning is specialized and not predictable for an average learner from the parts alone.

Etymology

Metasomatic joins Greek parts meta- meaning 'change', as in metamorphosis, and -somatic from soma meaning 'body'. So, think of a rock's 'body' being changed by fluids, which is exactly what metasomatic describes in geology.
