palindrome

According to the MacMillan Dictionary, a word, phrase, or sentence that reads the same forward and backward, as »Otto«, »Madam I'm Adam« and »Was it a cat I saw?«. Differs from the palimpsest, where earlier writing is erased partially or completely, and the anagram, where there is a reordering of letters with an implicit or explicit connecting idea, as in »best in prayer« for Presbyterian and »evil« for veil.
