From Greek ōsmos 'a push,' via the term osmosis coined by Graham in 1854 for solvent movement through membranes.
Relating to or involving osmosis, the passage of solvent molecules through a semipermeable membrane.
From osmosis + -ic. Osmosis was coined in 1854 by Thomas Graham from Greek ōsmos 'a push, impulse,' from ōthein 'to push, thrust.' Graham chose the word to describe how solvent is 'pushed' through a membrane from a region of low solute concentration to high. Key roots: *wedʰ- (Proto-Indo-European: "to push, strike").
