A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward, ignoring spaces, punctuation, and capitalization. The term comes from the Greek words "palin" (again) and "dromos" (way, direction).
Palindromes have fascinated people for centuries and appear in literature, mathematics, and even genetic sequences. They're often used in wordplay, puzzles, and as a form of linguistic art. Some cultures even consider certain palindromic dates or times to have special significance.
