Polluter → It is formed from "pollute" (from Latin "polluere", meaning to defile or make unclean) and "-er" (meaning a person who). A polluter is a person or entity that makes something unclean, particularly in the context of the environment.
Think of someone who 'defiles' or 'makes unclean' ('polluere') something, and the '-er' indicates that this person is the one doing the action. This helps you remember that a polluter is someone who makes the environment dirty.
