What is the longest (a)palindrome word and (b)palindrome sentence in the world?

Question

I would like which official language in the world has the longest palindrome (single word as well as whole sentence).

Answer 1

My favourite English palindromic sentence is: "A man, a plan, a canal - Panama!" Strictly speaking it is not a sentence because it contains no verb, but don't you go all pedantic on me.

Actually, the world's first conversation was palindromic. He said "Madam, I'm Adam", and she simply replied "Eve".

Answer 2

At 8:02 PM on the 20th of February 2002 it was 20:02 02/20 2002 (if you live in the US), or 20:02 20/02 2002 (if you live in the rest of the world). Either way, it was the best of times, it was the tseb of times, it was a palindromic time. In honor of the event, I wondered if I could create the world's longest palindrome. A search for world's longest palindrome revealed that "In 1980, Giles Selig Hales claimed to have written the world's longest palindrome, which consisted of 58,795 letters." That didn't seem too hard to beat. And in fact, in a few hours I was able to write a program to create a palindrome with 63,647 letters (and later I updated the program and got 72,046 letters).

Please don't ask me to put it here you will have to look for yourself

Answer 5

I think you'll struggle to find alot of people on here who know what a palindrome actually is.

Madam, I'm Adam

Answer 6

There is a Finnish word 'Saippuakauppias' which means a soap vendor - the Finns I work with claim that this is the longest palendromic word, that is actually used, in the world.

As for phrases, I like 'A Toyota's a Toyota'.
