8-Letter Palindromes
Genuine 8-letter single-word palindromes are essentially nonexistent in standard English — there is no widely recognised dictionary word exactly 8 letters long that reads the same both ways.
Where to look instead
Palindrome words tend to cluster at odd lengths. For examples near 8 letters, the richest pools are seven-letter words like racecar and deified and nine-letter words like malayalam and rotavator. For the record-breakers — including the 12-letter tattarrattat — see the longest palindromes.
