Morphology

eustatic = eustasy (opaque) = eu + stasis + eustasy + ic

The adjective is formed regularly from the technical noun 'eustasy' by the productive suffix '-ic'.

Etymology

The word eustatic comes from the Greek parts eu- meaning 'well' and -static from stasis meaning 'to stand'. Think of static as 'standing' or 'not moving', so eustatic refers to the ocean's overall 'standing' level, that is, changes in global sea level rather than local changes.
