Question

ex -- madam

Answer 1

its TATTARRATTAT and also i guess MALAYALAM.

Answer 2

You're talking about palidromes, like "racecar" and "macadam."

According to the other thousand times this question has been asked:
The longest palindromic word in the Oxford English Dictionary is tattarrattat, coined by James Joyce in Ulysses for 'a knock on the door.' The Guinness Book of Records gives detartrated, the past tense of detartrate, a somewhat contrived chemical term meaning to remove tartrates. Rotavator, a trademarked name for an agricultural machine, is often listed in dictionaries. The term redivider (i.e. someone or something that redivides) is used by some writers but appears to be an invented term - only redivide and redivision appear in the "Shorter Oxford Dictionary". Malayalam, an Indian language, is of equal length.

Saippuakauppias, Finnish for "soap vendor", is claimed to be the world's longest palindromic word in everyday use. A meaningful derivative from it is saippuakalasalakauppias (soapfish bootlegger). An even longer effort is saippuakuppinippukauppias (soapdish batch seller) Koortsmeetsysteemstrook, is probably the longest palindrome in Dutch, and Kuulilennuteetunneliluuk (bullet flightway tunnel hatch) is the longest palindrome in Estonian.

Answer 3

I think you are talking about palindrome. Here are some longest single-word palindromes, with two entries: “saippuakivikauppias,” which means “soap stone dealer”; and “solutomaattimittaamotulos,” which means “the result from a measurement laboratory for tomatoes.” Depending on who you ask, “tattarrattat,” “kinnikinnik,” or “detartrated” is the longest single-word palindrome in English, though some would say these words are not really part of the English language, since they are contrived or almost never used

Answer 4

Assuming you're talking about English words only, the answer is kinnikinnik (which is more commonly spelled kinnikinnick). It's a substitute for tobacco, formerly smoked by American Indians. For plenty of pictures of the plant they used, see http://images.google.com/images?hl=en&q=kinnikinnik&gbv=2 .

(Regarding the answer immediately above mine:
"tattarrattat” was just a creation of James Joyce, used once by him and never seen again (except in posts like this one). Neither it nor "detartrated" appear in any of the 931 dictionaries collected at onelook.com. But "kinnikinnick" and its alternate spelling are listed; see http://dictionary.reference.com/search?q=kinnikinnick&r=66 .

Answer 5

the longest word in dictionary --- " SMILES " . There is a "mile" in between first S and the last S . One word I know which can be read in both directions is " MALAYALAM " i,e, language of Kerala state.

Answer 6

MALAYALAM - KERALITE'S LANGUAGE
