Longest English Palindrome

Although saippuakivikauppias is the longest palindromic word, what is the longest English palindrome?

You’ll find different claims to the longest palindrome word in English depending on which source you refer to. See what I did there? Refer is also a palindrome!

  • Oxford English Dictionary: tattarrattat (12 letters) – an onomatopoeia for the sound of a knock on the door
  • Guinness World Records: detartrated (11 letters)  – of or relating to something from which tartrates have been reduced or removed through a detartration process

In addition, Rotavator (9 letters) is the name of an agricultural machine. But should we consider proper names as palindromes?

Similarly, redivider (9 letters) which is not listed in dictionaries seems to be an invented word that’s based on the word redivide. Hmm, should a made up word count as a palindrome?

Finally, Malayalam (9 letters) is a Dravidian language spoken in some southern states of Indian. Again, a proper name.

While all of these words are English palindromes, none are used by English speakers on a daily basis.

More common, but shorter English palindromes are civic, level, kayak, and radar. However, I must point out that radar is actually an acronym meaning radio detection and ranging.
