The following array of "*'s" 'masks' four three letter words which are to be read in the usual practice of left to right, and top down.

* * * * * * * *

Now here are some considerations.
1. Letter frequency is not restricted.
2. When all places are filled, all letters are rotated one place (direction is immaterial) around the square. At that point you must still have four three letter words.
3. Common English words are preferred.

(Words borrowed from other languages are acceptable, but try to limit words rarely found in English.)

Restricting all four words of each grid to be distinct, is there such a set of grids that -- in addition to being a valid solution to the given problem -- where one can place a letter in the center of the grid and have the middle row and middle column of each spell valid English words?
