- The resulting words (experimentationify and operationify) are not well-formed words and do not exist. In this case the two affixes that I utilized “ion” and “ify” do not work together and result in nonsense words most of the time. These two nonsense words are examples of constraints. They’re considered to be constraints because the ordering of affixes is too complex. However, there are always exceptions. For instance, the word “electionify” utilizes both the “ion” and “ify” affixes and is a valid word. To be honest, I expected all three of these words to be constraints.
