According to the Guinness Book of Records, the longest palindrome in the world is saippuakivikauppias. The word is somewhat artificial but plausible and it means a dealer in lye or caustic soda. There are 19 letters in saippuakivikauppias.
Finnish works well in palindrome construction because it is a synthetic language that uses a lot of affixes attached to word stems. That makes for a lot of long words. But when it comes to the longest words found in a dictionary, German takes the cake. Take a look at the monster below:
Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz
Let that sink in for a while.
It means a law that governs the transfer of beef labeling supervision tasks.
