An anagram is a word or phrase formed by rearranging the letters of another word or phrase. For example, the word “listen” can be transformed into “silent.” Anagrams are often used in puzzles, word games, and as a form of entertainment in literature. Anagrams can also reveal hidden meanings or connections between words. They are popular in various cultures and languages, and some famous authors, like Edgar Allan Poe, have used them in their works. Additionally, anagrams can serve as a fun way to create pseudonyms or nicknames.
