Can't be something like a palindrome (exp. RaceCar > raCecaR) since there are only 3 palindromes in english and none of them would make sense (kinnikinnikdetartratedaibohphobia From WikiPedia)
there are actually more than 3 palindromes in english the issue would be finding a palindrome that fits the amount of characters and has 1 letter in the middle that isnt repeated
