I am presenting this only to my smart friends. See if you can figure out what these words have in common.
Are you peeking or have you already given up? Give it another try . Look at each word carefully.
Answer: No, it is not that they all have at least 2 double letters.
(Thought I had the answer, but I did not go far enough.)
In all of the words listed, if you take the first letter, place it at the end of the word,
and then spell the word backwards, it will be the same word.
