Osmotic is an adjective that means having the properties of osmosis (a gradual assimilation of knowledge).
The Greek word Omos (OSE mose) means ‘thrusting’ or ‘pushing.’ You could say that when something osmotic is taking place, it is being thrust or pushed in some sense or other. When the word is used in a medical sense, it refers to something being pushed through a membrane. But used in an everyday context, an osmotic process may simply be something effortlessly or unconsciously assimilated, for example: Cheryl never took a music lesson. But there is something osmotic about the way she learned to play the violin as a result of growing up in a musical family.
