Devolutionary → It is formed from "de-" (meaning down or away) and "volutio" (from Latin, meaning to roll or turn). The suffix "-ary" indicates relating to. Thus, the word refers to something that relates to the process of rolling down or transferring power to lower levels.
Think of 'rolling down' ('de-' means down and 'volutio' means to roll') to remember that 'devolutionary' relates to the transfer of power to lower levels.
