palindrome
A palindrome is a word or sentence that reads the same forward as it does backward. The words a and I are perhaps the simplest and least interesting palindromes; the word racecar and the name Hannah are more interesting and illustrative. Neither spaces nor punctuation are usually taken into consideration when constructing sentences that are palindromes -- one of the most famous palindromes is "A man, a plan, a canal, Panama" -- but when the spaces are properly positioned as well, so much the better. An example would be the also famous palindrome "Able was I ere I saw Elba," purportedly spoken by Napoleon, referring to his first sighting of Elba, the island where the British exiled him.
