Trampler → It is formed from "trample" (from Middle English "tramplen", meaning to tread heavily) and "-er" (meaning a person who). A trampler is a person who treads heavily or crushes underfoot.
Think of someone who 'treads heavily' — that's what a trampler does, and the '-er' just means a person.
