A palindrome is a nifty little word or sentence which can be read the same way both forwards and backwards. The following is a classic example of a palindrome concerning Theodore Roosevelt referring to how the United States borrowed a strategic piece of Central America for nearly a century:
A man, a plan, a canal, Panama

A palindrome is a sequence of words whose letters are the same backward as forward. Note that this definition does not mention making sense. Few palindromes make sense, fewer still make sense and are grammatically correct sentences, and even fewer sound right to the ear. The longer a palindrome is, the less likely it is to make sense. And the longest palindromes, which run into the tens of thousands of words, make no pretense of making sense.

Bob, radar. Backwards & forwards, they’re palindromes. What may be the longest single palindromic word?
Well, my request for palindromes has been answered! Here is a summary of all the ones that were posted to the net or sent to me via mail. Many thanks to all who responded.

If you are wondering why they call me "Palindrome," well, it is because my name is BOB. Although the name "BOB" is not the most sophisticated or romantic name around, I'm here to tell you that having a name that belongs to a fine group of words and sentences that cleverly say the same thing backward as they do forward, is surely a fantastic consolation.

They're very hard to write. My only major effort in this field is the following 306-word masterpiece, Dog Sees Ada, composed in 1991. You may expect a grander effort, to be titled Seid Ada (German for "To Be Ada") in 2002. I have a rough idea for the plot of Seid Ada but I haven't yet figured out how it will end.
Writing a long palindrome requires patience and a keen eye for hidden words. If you've ever wandered the aisles of a grocery store, noticing the "lonely" in "Tylenol," the "nosy" in "Tyson," or the "soiree" in "Cheerios," there is a decent chance that you, too, could compose such a work.
This section is limited to single-word palindromes only. I appreciate contributions to this page, but I am not including sentences or phrases which are palindromes, since there are other websites which list large numbers of them. Principal contributors to this section are Dan Tilque, Stuart Kidd, Philip Bennett, and Charles Turner.
Everyone knows what a palindrome is: a word that reads the same backwards as forwards (except for spaces and punctuation). Maybe the fact that everyone knows about them is why it's taken me a year and a half to get around to writing about them.

Beginning with the decimal representation of any integer N, reverse the digits and add it to N. Iterate this operation. Typically you will soon arrive at a palindrome, i.e., a number that reads the same forwards and backwards. For example, starting with 39, we have 39 + 93 = 132. Then 132 + 231 = 363 = palindrome.
