I could not figure it out and had to look at the answer. See if you can
 figure out what these words have in common.
 
          Banana
          Dresser
          Grammar
          Potato
          Revive
          Uneven
          Assess
 
          Are you peeking or have you already given up?
 
          Give it another try . . .
 
        
          Go back and look at them again; think hard.
 
          OK . . . Here You Go . . . Hope You Didn't Cheat.

  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.
 
          Did you figure it out? Even if you didn't, don't worry.  Just send it to more people and stump them; then, you'll feel better, too.
