Morphology

Neptunism = Neptune (semi-transparent) = Neptune + ism

Derived from the name 'Neptune' (sea) plus the doctrinal suffix '-ism'; the sea connection is logical but the specific historical geological claim about rocks formed by water is specialized and not obvious to an average B1 learner.

Etymology

Neptunism comes from Neptune ('sea') and the ending -ism ('belief'). It names the old idea that many rocks were made by water, so the word links 'sea' to the belief that water formed the outer layer of the Earth.
