Yeah, he seems really excited, but it's not what he thinks it is.

Synonyms & Antonyms

Root Explanation

Undeceive → It is formed from "un-" (meaning not) and "deceive" (from Latin "decipere", meaning to ensnare or deceive). The word "undeceive" means to free someone from deception or to reveal the truth, thus making them not deceived.

Memory Tip

Think of 'not' ('un-') allowing someone to see the truth instead of being 'ensnared' ('decipere') by falsehoods.
