The grid is split into four rows which represent categories. Use the given words to find groups of four that have something in common and sort them into the rows. Some cells will need to be rebuses (multiple letters in one square). Cells are sorted ALPHABETICALLY from left to right within each row - the order of the groups does not matter.
Clever idea! I got stuck for a while trying to make the letters into actual words that were all part of the same category, instead of treating each entry as an actual "thing" on its own... frustrating. LOL. Once I figured out where I was goofing up, solving was much more fun!
