Etymology
The word 'osmotic' is built upon the Greek root ōsmos, meaning "a push" or "thrust." This root is itself derived from the verb ōthein, "to push." The scientific term 'osmosis' was coined in the mid-19th century to name the biological process where a solvent seems to be "pushed" through a membrane. The suffix -tic, of Greek origin, is used to form adjectives. Thus, 'osmotic' literally means "pertaining to a push," which elegantly captures the fundamental driving force behind the physical process of osmosis, where the differential in solute concentration acts as the impetus for solvent movement.
