A plagiarist is someone who takes the work of another person and passes it off as their own. The term can be broken down into three parts: TAKER (5 letters), PIRATE (6 letters), and IMITATOR (8 letters). A TAKER is someone who takes something without permission, a PIRATE is someone who steals or copies something without permission, and an IMITATOR is someone who copies the style or behavior of another. Therefore, a plagiarist is someone who takes, pirates, and imitates the work of another person without permission.
