Anagrams are words that are formed by rearranging the letters of another word. For instance, “silent” is an anagram of the word “listen” because it uses the same letters. They can be used to create commentary, synonyms, antonyms (or antigrams), puzzles, pseudonyms, or even change proper nouns into sentences. Anagrams date back to the time of the ancient Greeks, who used them to find hidden messages in names. Some examples of anagrams include evil = vile, heart = earth, a gentleman = elegant man, and dormitory = dirty room.
