OT can you figure it out?

[PolarBear]

This is for smarties. 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.

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 Cool.

Answer: No, it is not that they all have at least 2 double letters.

Answer:
In all of the words listed, if you tak e 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?
