: a word, verse, or sentence (such as "Able was I ere I saw Elba") or a number (such as 1881) that reads the same backward or forward

Did you know?

Palindrome comes from Greek palindromos, meaning "running back again," which itself is from palin ("back," "again") and dramein ("to run"). Nowadays, we appreciate a clever palindrome—such as "Drab as a fool, aloof as a bard" or "A man, a plan, a canal: Panama"—or even a simple one like "race car," but in the past palindromes were more than just smart wordplay. Some folks thought they were magical, and they carved them on walls or amulets for protection.
