The longest known palindromic word is saippuakivikauppias (19 letters), which is Finnish for a dealer in lye (caustic soda).A palindrome is a word or phrase where the letters read backwards, give the same word or phrase, eg: the phrase 'Madam I'm Adam', with the reply 'Eve'.Some baptismal fonts in Greece and Turkey bear the circular 25-letter inscription NIYON ANOMHMATA MH MONAN OYIN, meaning wash (my) sins, not only (my) face. This appears at St Marys Church, Nottingham, at St Pauls, Woldingham, Surrey and at other churches.
