Anagram

An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.^[1] For example, the word anagram itself can be rearranged into nag a ram; which is an Easter egg in Google when searching for the word "anagram".^[2]

The original word or phrase is known as the subject of the anagram. Any word or phrase that exactly reproduces the letters in another order is an anagram. Someone who creates anagrams may be called an "anagrammatist",^[3] and the goal of a serious or skilled anagrammatist is to produce anagrams that reflect or comment on their subject.
