Proofreader → It is formed from "proof" (from Old French *proef*, meaning a test or trial) and "reader" (from Old English *rædere*, meaning one who reads). A proofreader is someone who reads a text to check for errors or to test its correctness.
Think of someone who is testing a text for errors ('proof') and is a person who reads ('reader'). This helps you remember that a proofreader checks written material for mistakes.
