Still uncertain as to wherther you are a budding genius?  Try the following!

See if you can figure out what these words have in common. 
1 Banana
2 Dresser
3 Grammar
4 Potato
5 Revive
6 Uneven
7 Assess
Are you peeking or have you already given up?
Give it another try - Look at each word carefully. 
(You'll kick yourself when you discover the answer.)
This Is so Cool.

Potential Answer:   each word has only 3 or 4 letters? Well that's not the answer we are looking for. 
No, it is not that they all have at least 2 double letters, nor is it about the vowel arrangements, tempting though they were at first glance.  


Answer: 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.

next problem:  can you think of another word in this category??
