Delusory → It is formed from "de-" (meaning down or away) and "ludere" (meaning to play). The word describes something that plays down or away from reality, leading to a false impression or illusion.
Think of something that 'plays away' from reality — 'de-' means down or away, and 'ludere' means to play, which helps you remember that 'delusory' refers to something that creates an illusion.
