mech·a·nism (m k  -n z m)n. 1. a. A machine or mechanical appliance. b. The arrangement of connected parts in a machine. 2. A system of parts that operate or interact like those of a machine: the mechanism of the solar system. 3. An instrument or a process, physical or mental, by which something is done or comes into being: "The mechanism of oral learning is largely that of continuous repetition" (T.G.E. Powell). 4. A habitual manner of acting to achieve an end. 5. Biology The involuntary and consistent response of an organism to a given stimulus. 6. Psychology A usually unconscious mental and emotional pattern that shapes behavior in a given situation or environment: a defense mechanism. 7. The sequence of steps in a chemical reaction. 8.
