In the 1800's when children recited the alphabet they ended with X,Y,Z, and per se, and. Per se actually means by itself, so what the children were actually saying is X,Y,Z, and by itself and. Over time, and per se and, said quickly over and over resulted in new word: ampersand.
After learning how and per se and became ampersand, I wonder if L,M,N,O,P will one day be it's own word, too.
Did you know the alphabet once had 27 letters? Are you a fan of the ampersand? Can you see LMNOP becoming an everyday word?
