Revolutionizer → It is formed from "re-" (meaning again) and "volutio" (from Latin, meaning to roll or turn) and "-izer" (a suffix indicating a person who performs an action). The word "revolutionizer" refers to a person who brings about a significant change or turns things around again in a new direction.
Think of someone who 'turns' things 'again' ('re-') to create a significant change — that's what a revolutionizer does.
