Word or phrase formed by rearranging the letters of a different word or phrase

An anagram is a puzzle where the player has to move all the letters in a word to make a new word. An example would be The Morse Code and Here Comes Dots. Anagrams are often used in fiction when a character wants to use a different name. For example, the Harry Potter character named Tom Marvolo Riddle made an anagram based on his name, "I Am Lord Voldemort", and began calling himself "Lord Voldermort".
