This topic has been done on Jeopardy! before. Best to explain with an example. A clue that said "bigger rodent" would be "largerbil" (larger gerbil), so you would write "largerbil" in the blank. Good luck!
As a continuation of the directions, each of two words has at least three letters overlap. I will also let you know which part comes first. From the example, bigger rodent = larger gerbil = largerbil, bigger and larger are in the same position, as are rodent and gerbil (both in the clue and the answer). I will write "switched" in the hint if they are in different spots. For instance, if the clue was "rodent that is bigger" = "larger gerbil" = "largerbil", I would write switched in the hint to let you know that the first part of the clue corresponds to the second part of the answer, and vice-versa. This should make it a little easier. All right, here we go, first question!
