Answer: 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. I thought I had it when I saw that the second letter was the same as the last letter but no.

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.
