This headline probably makes no sense. Allow me to elaborate. A word that is plural usually ends in an S. What if you added another S to that plural? Would you loop around to get a singular word again? Absurd I know. Until I thought of the word Princes and the extra S version Princess. Plural + S = Singular. My mind is blown. Are there any other words like this is wonder..? Answers on the back of a postcardss please.
