What These Words Have in Common? (Puzzle)
This Is Cool. Answer: No, it is not that they all have at least 2 double letters.
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? No? Then send it to more people and stump them as well. Then, you'll feel better too
