Morphology

nonequilibrium = equilibrium (transparent) = non + equilibrium

The prefix 'non-' straightforwardly negates the noun 'equilibrium' to give the meaning 'not in equilibrium' in scientific contexts.

Etymology

Nonequilibrium is formed from non- meaning 'not' and equilibrium meaning 'balance' or 'a steady state'. So, to call something nonequilibrium (as an adjective) is to say it is 'not in balance' and often changing, a term used a lot in science.
