anagram

An anagram is a type of word play, the result of rearranging the letters of a word or phrase to produce a new word or phrase, using all the original letters exactly once; for example, the word anagram can be rearranged into nag-a-ram. Someone who creates anagrams may be called an "anagrammatist". The original word or phrase is known as the subject of the anagram. Anagrams are often used as a form of mnemonic device as well.
