An anagram is a word or phrase made by rearranging the letters of another word or phrase. Poets and writers use anagrams as a form of wordplay, sometimes to create hidden names, playful puzzles, or extra layers of meaning.
For the result to count as an anagram, the same letters must be used, with no extras or omissions.
The transposition of letters from a word or phrase to form a new word or phrase. All schoolboys know that T.S.Eliot = toilets.
Example
Listen closely: SILENT is hidden inside the same letters,
like a secret the word has been waiting to say.
