A palindrome, by definition, is a word, phrase, verse, sentence, or even poem
that reads the same forward or backward. It stems from the Greek word
palindromos: palin, meaning again, and dromos, meaning a running.
Combining the two together, the Greek meaning gives us, running back again.

A palindrome poem is a mirror image of itself. A carefully planned poem is written
and then, after a good dividing word in the middle, the poem above is written
exactly backwards and must still make perfect sense.
