Legilimency

Legilimency is, in the fictional realm of J.K. Rowling's Harry Potter series, a branch of magic involving the practice of extracting emotions and memories from another person's mind, in a manner akin to "mind reading."

Someone who practices Legilimency is known as a Legilimens. A skilled Legilimens would be easily able to detect truth or deception and would also be able to tell what a person was thinking or remembering.

In Harry Potter and the Order of the Phoenix, former Death Eater and Hogwarts Potions Master Severus Snape uses his talent in Legilimency to teach student Harry Potter to stop mental intrusion by Lord Voldemort.

This nonexistent word was created by joining forms of the Latin words Legens (reader) and Mens (mind) with "-mancy" (which means divination).
