Stimulate → It is formed from "stimulus" (from Latin, meaning a goad or incentive) and the suffix "-ate" (meaning to make or to cause). The word "stimulate" means to make something active or to cause an increase in activity.
Think of a 'goad' or 'incentive' ('stimulus') that makes something more active — that's why to stimulate means to encourage activity.
