uneven.... Nefen
voodoo.... OdoIosee how the words are like mirror images when the first letter is taken off? when u get a quesiton like that, dont just think what do their definitions have in common, but their spellings also.
It's already been said, but by removing the first letter of each, you create what is called a "palindrome," which is just a fancy way of saying a word that is spelled the same backwards and forwards.
By the way, the correct spellings are "grammar" and "potato."
