A palindrome is a word, phrase, number, or sequence that reads the same backward as forward. Common examples include words like “level,” “radar,” and “civic.” Phrases can also be palindromic, such as “A man, a plan, a canal, Panama!” which ignores spaces and punctuation. Palindromes can be found in various languages and are often used in puzzles and word games. They are not only limited to text; numbers can also be palindromic, such as 121 or 12321. The study of palindromes can be a fun way to explore language and symmetry.
