osmosis
UK: ɒzˈməʊsɪs | US: ɑːzˈmoʊsɪs
n. 1. The gradual, passive diffusion of molecules (e.g., water) through a semipermeable membrane from a region of low solute concentration to high concentration.
n. 2. (Figurative) The subtle, unconscious absorption of ideas, knowledge, or culture over time.
Derived from Greek ōsmós ("push, impulse"), osmosis originally described the physical phenomenon of liquid being "pushed" through a membrane due to pressure differences. The term was coined in 1854 by British chemist Thomas Graham, who adapted the Greek root to describe this passive process. The figurative sense emerged in the early 20th century, likening intellectual absorption to molecular diffusion.
