Frequently Asked Questions About Palindrome Checker
What is a palindrome?
A palindrome is a word, phrase, or sequence that reads the same forwards and backwards. Common examples include "racecar", "madam", and "A man, a plan, a canal: Panama".
Does it ignore spaces and punctuation?
Yes. The checker strips all spaces, punctuation, and converts to lowercase before checking. This allows you to test full sentences and phrases accurately.

The longest known English palindrome is "tattarrattat" (12 letters), coined by James Joyce in Ulysses meaning a knock on a door. There are also very long palindromic sentences constructed for wordplay.
