 (ŏz-mō′sĭs, ŏs-)
n. pl. os·mo·ses (-sēz)
a. Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal solute concentration on both sides of the membrane.
b. The tendency of fluids to diffuse in such a manner.
2. A gradual, often unconscious process of assimilation or absorption: learned French by osmosis while residing in Paris for 15 years.

[From obsolete osmose, from earlier endosmose, from French : Greek endo-, endo- + Greek ōsmos, thrust, push (from ōthein, to push).]
