Etymology
The word devolution is built on the Latin verb devolvere, meaning "to roll down." This literal sense of something moving downwards evolved into the metaphorical idea of a transfer of authority or responsibility from a higher to a lower level. The prefix de- reinforces this downward direction, while the suffix -ion nominalizes the action. Thus, the core logic of the word moves from the physical act of rolling down to the abstract process of power or quality being passed down or declining.
