A palindrome is a word or phrase that can be correctly (and identically) read in either direction - Dr. Doolittle's "Push-me-pull-you" was perhaps a palindromedary - or perhaps a camelemac...
Phrase palindromes come in two types - "perfect" palindromes, where spaces and punctuation form part of the palindrome text (as in "Able was I ere I saw Elba"), and "imperfect" palindromes, where punctuation and spaces must be ignored or adjusted when changing from one direction of reading to the other (as in "Madam I'm Adam").
Single-word palindromes are rare, and most are only three or four letters - we intend to find them all and include them in our "list of lists".
For now, here are just a few (we are NOT going to count single-letter words such as "I", although we might include acronyms such as AEA):
exe (a river)
hah, heh, huh
mam, mom, mum
