The idea that cultural changes happen when ideas or practices spread from one culture to another, often from more developed to less developed cultures.
Diffusionism explains how Western ideas influenced many other cultures around the world.
Diffusionism is formed from "diffusio" (from Latin, meaning spreading out) and the suffix "-ism" (meaning a doctrine or belief). The term refers to the theory that cultural phenomena spread from one society to another.
Think of 'spreading out' ('diffusio') to remember that diffusionism is about the spread of cultural ideas and practices.
